Police in Washington have released the names of seven of the 12 victims killed in Monday's shooting rampage at Washington Navy Yard.

- 59-year-old Michael Arnold

- 53-year-old Sylvia Frasier

- 62-year-old Kathy Gaarde

- 73-year-old John Roger Johnson

- 50-year-old Frank Kohler

- 46-year-old Kenneth Bernard Proctor

At the time of the rampage, suspected shooter Aaron Alexis was an information technology employee with The Experts, a company that was a Defense Department subcontractor on a Marine computer project, authorities said.

Valerie Parlave, head of the FBI's field office in Washington, said he had legitimate access to the base as a defense contractor and used a valid pass.

Alexis had been a full-time Navy reservist from 2007 to early 2011, leaving as a petty officer third class, the Navy said. It did not say why he left. He had been an aviation electrician's mate with a unit in Fort Worth.

FBI officials have released the first photos of Aaron Alexis, deceased, who they say is the shooter that went on a rampage killing 12 individuals at the Navy Yard in Washington, D.C., early Monday morning. Authorities said they believe the shooter acted alone.

Alexis served in the U.S. Navy Reserves as an Aviations Electrician for four years, enlisting in New York in May 2007 and being discharged in January 2011, according to the U.S. Navy.

Watch the press conference where the FBI identified the shooter as Aaron Alexis:

Chris Childs, director of TheBlaze TV's "The Pat & Stu Show," told us he frequently visited the Thai restaurant Alexis worked at in Fort Worth, and got to know him over time.

"The thing that really struck me was the fact that he was really big into the shooter video games," Childs told TheBlaze. "We would talk about all kinds of stuff... I know the family that owns the Thai restaurant is devastated because they can't imagine that he would do this. I can't imagine it."

Childs also said Alexis seemed like an "extremely normal guy." He said the deceased shooter also spoke about his "out of the blue" visit to Thailand.

Further, Seattle Police said Alexis was arrested in 2004  for "shooting out the tires of another man's vehicle in what Alexis later described to detectives as an anger-fueled blackout.'" He was booked in the King County Jail for malicious mischief.

On May 6, 2004, two construction workers saw Alexis "pull a gun from his waistband and fire three shots into the two rear tires of their Honda," according to Seattle Police. The workers apparently told police he had been upset over the parking situation nearby and had "stared" construction workers down every day over the past month.

Alexis told police he had been "mocked" by the workers and had an anger-fueld "blackout." Seattle Police also say he told them he was present during the 9/11 terrorist attacks and explained "how those events had disturbed him."

Seattle detectives talked to Alexis' father, who said he suffered from anger management problems associated with PTSD.

Alexis was also arrested in September 2010 for accidentally discharging a firearm, according to a police report obtained by KXAS-TV. However, the documents reportedly indicate he was never officially charged.

The police report reveals that a woman called police in September 2010 after she heard a "loud pop" and saw a "hole in her floor."

Police then interviewed Alexis who said that "he did have a gun" and claimed to be "cleaning it when it went off." A gun cleaning kit was found near the firearm.

"After investigating the situation, Aaron was taken to 350 W. Belknap and booked," the police report concludes.

Alexis' roommate until about four months ago was Texas man Nutpisit Suthamtewakul who told KDFW-TV he lived with Alexis for three years.

Suthamtewakul described Alexis as a great guy and reportedly said he was stunned to learn his ex-roommate may have committed such a heinous act.

The ex-roommate added that Alexis had a concealed handgun license, worked as a computer technician and spoke Thai.

Moreover, Suthamtewakul said Alexis spent his free time at a local Buddhist temple.

Alexis was born in Queens, New York in 1979, according to KDFW-TV.
