A video footage of Washington DC Navy Yard gunman Aaron Alexis prowling the corridors of the complex as he hunts for victims has been released by the FBI.
During a press conference, an FBI spokeswoman said Aaron Alexis, 34, believed he was being controlled by extremely low frequency radio waves.
Aaron Alexis killed 12 people in the rampage on September 16 before he was shot by police in a running gun battle.
Officials say they believe he did not target any specific individuals.
Clear video footage taken from the Navy Yard’s gate and at locations on site shows Aaron Alexis calmly entering the complex.
Later clips show him stalking a corridor armed with a shotgun and checking if a room is empty, before running down a flight of stairs.
The agency also released images of a weapon Aaron Alexis used during the shooting.
He had written “my ELF weapon” – apparently referring to extremely low frequency waves – and “Better off this way!” on a Remington 870 shotgun.

A photo of his backpack, which he used to bring the weapon into the building and then left in a men’s toilet, was also published by the FBI.
Valerie Parlave, head of the FBI’s field office in Washington, said in Wednesday’s news conference that they were still investigating Aaron Alexis’ background and motivations.
But she noted the former Navy reservist had a well-documented history of mental health issues.
Valerie Parlave said: “At this point I can confirm that there are multiple indicators that Alexis held a delusional belief that he was being controlled or influenced by extremely low frequency, or ELF, electromagnetic waves.
“The etching… is believed to reference these electromagnetic waves.
“In addition, a document retrieved from the electronic media stated <<ELF attack is what I’ve been subject to for the last three months, and to be perfectly honest that is what has driven me to this>>.”
Valerie Parlave added: “ELF technology was a legitimate programme for naval subtonal submarine communications.
“However, conspiracy theories exist which misinterpret its application as the weaponisation of remote neural frequencies for government monitoring and manipulation of unsuspecting citizens.”
As an IT subcontractor, Aaron Alexis had an entry pass to the Navy Yard complex.
Investigators say he acted alone and died on the third floor of Naval Sea Systems Command headquarters after about an hour of exchanging gunfire with officials.
The shooting has led to questions about how Aaron Alexis received the security clearance necessary to be a contractor and enter the installation and prompted calls to review the government vetting process.
Also on Wednesday, Washington Police Chief Cathy Lanier told local media a Washington DC police officer was shot in the chest while responding the shootings but was saved by protective gear.
Another police officer was shot in the leg and is currently recovering in hospital.
Ex-US Navy reservist Aaron Alexis, who killed 12 people and wounded eight at a Washington DC Navy base, had received treatment for mental health issues, US media have reported.
Aaron Alexis, 34, was treated for paranoia, trouble sleeping and hearing voices, the Associated Press reported.
A contractor for the Navy, Aaron Alexis had a valid pass for the secure site at the Washington Navy Yard, authorities said.
Aaron Alexis was shot and killed by police during the attack.
On Tuesday, the US capital remained in a state of shock and mourning.
Defense Secretary Chuck Hagel laid a wreath at US Navy Memorial Plaza in honor of the Navy Yard victims.
A Washington Nationals baseball game originally scheduled for Monday night was rescheduled to Tuesday afternoon – the baseball stadium is just blocks from the Navy Yard.
The flag flew at half-mast over the White House, where hours after the attack President Barack Obama mourned “yet another mass shooting”.
Secretary of the Navy Ray Mabus has ordered a physical security review of all Navy and Marine Corps installations.
White House spokesman Jay Carney said President Barack Obama would continue to push for tighter gun control laws in the wake of Monday’s shooting.
The shooting began about 8:20 local time on Monday, when a gunman apparently shot his way into the heavily guarded Building 197, headquarters for Naval Sea Systems Command, which builds and maintains ships and submarines for the Navy.

Witnesses said the gunman sprayed bullets in a hallway and fired from a balcony down on to workers in an atrium at the heavily secured installation in the US capital.
Aaron Alexis was armed with a shotgun legally purchased in Virginia, as well as one handgun authorities say may have been obtained inside the naval installation.
The attack only ended when police stormed the building and shot him dead, police said.
“There is no question he would have kept shooting,” Washington Police Chief Cathy Lanier told reporters on Monday.
On Tuesday, authorities said they believed Aaron Alexis had acted alone and that all victims – ranging in age from 46 to 73 – had been identified.
Authorities have revealed no motive for the attack, and have begun combing the US for hints about Aaron Alexis’ past.
As an employee of an IT contractor, Aaron Alexis apparently had a card granting him access to the building – even though he had had several run-ins with the law and had been discharged from the Navy under a cloud, authorities said.
“It really is hard to believe that someone with a record as chequered as this man could conceivably get, you know, clearance to get… credentials to be able to get on the base,” Washington DC Mayor Vincent Gray told CNN.
Aaron Alexis left the Navy as a petty officer 3rd class, after serving full-time in the naval reserve from 2007-11.
He received two routine medals for his service in the Navy: the National Defense Service Medal and the Global War on Terrorism Service Medal.
Aaron Alexis separated from the Navy reserves under what is called a general discharge, a status that suggests misconduct.
He had been cited for misconduct – including insubordination, disorderly conduct and excessive absences from work – at least eight times during his Navy career, the Washington Post reported on Tuesday.
According to media reports, Aaron Alexis was a Buddhist convert who had had two previous gun-related brushes with the law.
In 2004 he was arrested in Seattle for shooting a construction worker’s car tyres, in what he described as an enraged “black-out”.
Aaron Alexis was questioned by Fort Worth police in 2010 after firing his gun through the floor of an upstairs apartment. He said it was an accidental discharge.
Also, in August 2008, Aaron Alexis was arrested for disorderly conduct in the state of Georgia, according to the Smoking Gun, a website that collects police and court documents. Details on the incident were not available.
On Tuesday, Aaron Alexis’ employer said the military should have made his record known.
“Anything that suggests criminal problems or mental health issues, that would be a flag. We would not have hired him,” Thomas Hoshko, chief executive officer of The Experts, told the Washington Post.
The IT contractor confirmed Aaron Alexis had worked since July at six different military installations and had only been at the Navy Yard for a few days before the shooting.
A government audit has found that budget cuts may have been the cause for lax security at the Washington D.C. Navy Yards where 12 people were shot dead and eight others were injured on Monday morning.
According to a yet-to-be-released government audit, federal oversight investigators concluded that the reduced security measures at the base left security risks unaddressed.
A report by the Department of Defense Inspector General’s office shows that they were concerned about the access that would be granted to outside contractors – like that of Aaron Alexis, the suspect who was killed by police during the Monday morning shooting.
The report states that the Navy “did not effectively mitigate access control risks associated with contractor installation access” to the Navy Yards.
Time Magazine published excerpts from the report after having been read portions by an unidentified federal official who had access to the Inspector General’s findings.
The security risks are placed squarely on the Navy administrators who were trying “to reduce access control costs”.
The process of gaining access to the administrative facility- where about 3,000 people work- is under severe scrutiny.
In a Monday night press conference, FBI assistant D.C. director in charge Valerie Parlave said that they concluded Aaron Alexis had legitimately accessed the building as his status as a contractor would have given him sufficient credentials to enter unquestioned.

“He utilized a valid pass,” Valerie Parlave said during the press conference.
Aaron Alexis, 34, became a full-time Navy reservist in 2007 but was dismissed in 2011 following a series of ‘misconduct’ violations.
As a contractor for a group working for a subcontractor used by Hewlett-Packard, Aaron Alexis had the proper identification to be allowed into Navy Yard’s Building 179 where he began shooting.
“He did have a secret clearance. And he did have a CAC [common access card],” said Thomas Hoshko, CEO of subcontracting group The Experts Inc who employed Aaron Alexis.
Asked when Aaron Alexis was supposed to start work, Thomas Hoshko told Reuters that it was unclear when Alexis was supposed to start his latest stint in the government facility: “That’s what I got to find out, if he was supposed to start today … It’s not clear to me.”
“We had just recently re-hired him. Another background investigation was re-run and cleared through the defense security service in July 2013.”
Another problem with Aaron Alexis that should have been flagged up by the security access system is that he had two prior arrests- one in 2004 for shooting someone’s tires in an anger-fueled “blackout” and another in 2010 when he said that he accidentally fired into a neighbor’s apartment while cleaning his gun.
The security assessment report cites the fact that a number of people with criminal histories were able to bypass the Navy Yard’s security without any alarm.
Time reports that the audit cited 52 instances where “convicted felons received routine unauthorized installation access, placing military personnel, attendants, civilians in installations at an increased security risk”.
The research into the security inefficiencies at Navy Yard began in September 2012 and carried on through August of this year. The final report will be published within the next 30 days.
Aaron Alexis’ family is “distraught” to learn that he carried the massacre, relatives said today.
A family member said that the mother and sister of the Washington Navy Yard shooter were also “shocked” that he could have done this.
While some neighbors and acquaintances described Aaron Alexis as “nice”, his father once told detectives in Seattle that his son had anger management problems related to post-traumatic stress brought on by the terrorist attacks of September 11, 2001.
He also complained about the Navy and being a victim of discrimination during his time as a Navy reservist from 2007 to 2011.
At the time of the shootings, Aaron Alexis worked for The Experts, a subcontractor on a Hewlett Packard contract to refresh equipment used on the Navy Marine Corps Intranet network.
After leaving the reserves, Aaron Alexis worked as a waiter and delivery driver at the Happy Bowl Thai restaurant in White Settlement, a suburb of Fort Worth, according to Afton Bradley, a former co-worker. The two overlapped for about eight months before Aaron Alexis left in May, Bradley said.
Having traveled to Thailand, Aaron Alexis learned some Thai and could speak to Thai customers in their native language.
A former acquaintance, Oui Suthametewakul, said Aaron Alexis lived with him and his wife from August 2012 to May 2013 in Fort Worth, but that they had to part ways because he wasn’t paying his bills.
Aaron Alexis was a “nice guy”, Oui Suthametewakul said, though he sometimes carried a gun and would frequently complain about being the victim of discrimination.
Oui Suthametewakul said Alexis had converted to Buddhism and prayed at a local Buddhist temple.
Aaron Alexis’ family is distraught to learn that he carried the Navy Yard massacre
The shooter’s family lives in a run-down area of Brooklyn called Bedford-Stuyvesant, which was known in the 1980s for being at the center of New York’s crack epidemic.
His mother Cathleen, 60, lives in a fourth floor walk up apartment worth $130,000 with other relatives.
The street was then sealed off by police and FBI agents who stood guard outside and refused to let anybody onto the side of the street where the house is.
Later the gunman’s brother-in-law Anthony Little, who is married to Aaron Alexis’ sister Naomi, 31, arrived and said: “The family are distraught…They’re shocked.”
Anthony Little said it had been several years since had Aaron Alexis spoken with his family in Brooklyn.
He added: “He is not as close as the normal person with his family.”
Monday at around 5 p.m. two FBI agents arrived and questioned neighbors and workmen who were inside the apartment doing renovations but left after 15 minutes and refused to answer questions.
Aaron Alexis, a 34-year-old civilian contractor from Fort Worth, Texas, was confirmed dead on Monday after the mass shooting which also left at least 15 people injured in the nation’s capital.

He shot dead 12 people at the Navy Yard in Washington DC today, but was described by friends as a fan of meditation and Buddhism “who didn’t seem aggressive”.
Two different portraits of Aaron Alexis have emerged, as his criminal record runs in contrast to the reports of friends and family.
He was arrested for gun-related incidents in 2004 and 2010, while he was also kept in jail in Georgia for two nights in 2008 for disorderly conduct.
Aaron Alexis had joined the Navy in 2007 but was kicked out in 2011, the year after the second gun arrest. In both gun cases, charges were never filed
He was a Petty Officer Third Class in the Navy prior to his dismissal.

No motive is known for the attack, whose dozen victims ranged in age from 46 to 73, said the authorities.
Police initially responded to reports of two other armed suspects, but after exhaustive searches Washington Police Chief Cathy Lanier said on Monday night they were all but certain that Aaron Alexis was the only gunman.
Witnesses said suspect Aaron Alexis sprayed bullets in a hallway and fired from a balcony down on to workers in an atrium at the heavily secured installation in the US capital.
Aaron Alexis was reportedly armed with an AR-15 semi-automatic rifle, a shotgun and a handgun that he took from a police officer at the scene.
Chief Cathy Lanier told reporters that the attacker “was engaged in shooting with police officers” when he died.

Aaron Alexis was formerly a petty officer 3rd class who served full-time in the naval reserve from 2007-11, said the US Navy.
It was not immediately clear why he left the military, but unnamed military officers told US media there had been a series of misconduct issues during his service.

Monday’s mass shooting occurred at a building that serves as the headquarters for the Naval Sea Systems Command, which builds and maintains ships and submarines for the Navy.
Washington Navy Yard is the US Navy’s oldest shore installation, first opened in the early 19th Century, according to the Navy.
At least one heavily armed gunman opened fire inside a building at the Washington Navy Yard killing at least 11 people and injuring at least 12.
Named as 34-year-old civilian contractor Aaron Alexis, the Fort Worth resident entered the cafeteria in the Washington military base brandishing an AR-15 rifle, shotgun and handgun and began shooting.
The FBI have said that Aaron Alexis died after launching his rampage, during which witnesses said he appeared to fire at selected targets and not randomly, but they have not disclosed how he perished.
Washington D.C.’s FBI field office reportedly said that they have “all assets out” as they search for one other possible shooter they described as a black man in his 40s or his 50s.
Washington D.C. police Chief Cathy Lanier said the other potential gunman were wearing a military-style uniform and has greying sideburns.
“It appears that we have at least 12 fatalities … it doesn’t get much more serious than that, obviously,” said Washington D.C. Mayor Vincent Gray.
“We have no known motive at this stage. We will continue the investigation to try and figure out what that motive is.”
Previously, Cathy Lanier said that law enforcement were searching for two individuals, one white and one black.
However, police have said they have identified the white individual and he’s not a suspect or person of interest.
“The big concern for us right now is that we have potentially two other shooters that we have not located at this point,” Cathy Lanier saidearlier this afternoon.
