Gunman: Accprding to NBC Washington, this man Aaron Alexis, 34, from Fort Worth, Texas is the Navy Yard shooter

The Washington Navy Yard gunman who killed 12 today has previously claimed to be suffering from PTSD after helping rescue efforts in New York following the 9/11 terrorist attacks.

Gunman Aaron Alexis was shot dead by responding officers after he opened fire inside a Navy facility around 8am on Monday morning.

Since he was identified as the shooter, reports have come out revealing that it was not the first time that he was involved in a shooting.

In 2004, he was arrested in Seattle for shooting the tires of someone’s car during an anger-fueled ‘blackout’.

‘He said that he didn’t remember pulling the trigger of his firearm until about one hour later,’ according to the Seattle police report.

Later he said that he felt the intended victim ‘disrespected him’.

The report states that his father said his anger issues stemmed back to his time in New York where he helped the rescue efforts following the September 11 terrorist attacks.

The shooter’s father told police ‘that his son had experienced anger management problems that the family believed associated [sic] with PTSD.’

He was arrested in relation to this instance but never charged, and the same outcome occurred in Fort Worth, Texas where Alexis was living in 2010.

He was arrested for discharging a firearm when his neighbor reported that Alexis fired a shot into their apartment. At the time, Alexis claimed that his hand slipped when he was cleaning his gun, accidentally shooting the weapon.

Today Alexis- who had three different types of guns on him when he was shot- killed at least 12 people in cold blood this morning at the Washington Navy Yard. The motive has not been revealed, speculation is growing his dismissal from the U.S. Navy for ‘misconduct’ in January 2011 may have inspired him to commit a deadly revenge.

It has also been revealed he was awarded the Global War on Terrorism Service Medal and the National Defense Service Medal prior to his discharge in January 2011.

The family of the Washington shooter are ‘distraught’ to learn that he carried the massacre, relatives told MailOnline today.

Despite the lack of acknowledged motive, one U.S. official has been quoted as saying Alexis was kicked out of the Navy in 2011 for a series of incidents of ‘misconduct’.

Law enforcement said that Alexis’ identity was confirmed by fingerprints and that he served in the U.S. Navy between May 5th, 2007 and January 31st, 2011, the date he was dismissed from the service.

A U.S. Navy spokesman said that Alexis was an ‘aviation electrician’s mate’ – ranked as a third class petty officer and served at the Naval Air Station in Fort Worth, Texas.

 

He is reported to have enlisted in New York and the Brooklyn native graduated from boot camp at Great Lakes, Illinois as an Airman Recruit.

Throughout the late 1990s to 2002, he was listed as living in Manhattan and Queens in New York City – and he still maintains his New York social security number and is registered as a voter in New York City.

Alexis, who worked as a civilian I.T. contractor at the military base in the nation’s capital, entered the cafeteria of Building 197 just before 8.15 a.m. brandishing an AR-15 semi-automatic rifle, shotgun and handgun and began shooting.

It is thought that he used another employee of the base’s identification card to gain entry to the heavily secured Building 197, where he carried out his deadly attack.

After SWAT teams swarmed the headquarters of the Naval Sea Systems Command the FBI said that Alexis was shot dead by officers.

During his rampage witnesses said he appeared to fire at selected targets and not randomly.

Washington D.C.’s FBI field office also 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.

According to a deleted Linked In profile, he attended Embry-Riddle Aeronautical University and worked for a tech firm.

A former roommate from Ft. Worth, the owner of Happy Bowl Thai restaurant, told NBC News he had not seen Alexis in three months.

Police records reveal that Alexis was arrested for accidently discharging a firearm at his Ft. Worth home in September 2010.

A witness who lived in a neighboring apartment told police that she heard a pop and then to her horror a hole appeared in her floor and ceiling.

Alexis told police he was cleaning his gun when while cooking and that his hands were slippery.
All charges against him were dropped.

Washington D.C. Metropolitan Police Department chief Cathy Lanier said the other potential gunman was wearing a military-style uniform and has greying sideburns.

 

‘It appears that we have at least 13 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.’

‘We don’t have any reason to suspect terrorism, but certainly it has not been ruled out.’

Previously, Washington D.C. police chief 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,’ Lanier said earlier this afternoon.

Witnesses reported one man described as an African-American male  dressed in military fatigues and armed with an AR-15 assault rifle opening fire upon entering the base at the Naval Sea System Command HQ.

Police are investigating whether the ID of a former Navy petty officer called Rollie Chance was used by Alexis to gain entrance to the the Navy Yard compound.

FBI investigators visited Chance’s home Monday but have not revealed how Alexis obtained the identification.

Todd Brundidge, an executive assistant with Navy Sea Systems Command, said he and other co-workers encountered a gunman in a long hallway of their building on the third floor. The gunman was wearing all blue, he said.

‘He just turned and started firing,’ Brundidge said.

Patricia Ward, who works at the Navy Yard, described how she was in the cafeteria when she heard ‘three gunshots, pow-pow-pow, straight in a row.’

‘All of the people that were in the cafeteria, we all panicked, and we were trying to decide which way we were going to run out,” she said to NBC News. “I just ran.’

 

Tim Hogan, a spokesman for Rep. Steven Horsford of Nevada, posted photos to his Twitter account of people helping someone who had been hit by gunfire.

The attacks came three days after al-Qaeda used the 12th anniversary of 9/11 to call for strikes on America.

The mass shooting was the deadliest in the United States since the massacre at Sandy Hook Elementary School in Newtown Connecticut last December, and the worst at a military base since 13 people were killed at Fort Hood, Texas, in 2009.

‘We don’t even know, most of us, ourselves, the identities of the victims at this stage,‘ said Washington D.C. Mayor Vincent Gray.

Three people, including a Washington D.C. police officer, were admitted to MedStar Washington Hospital Center with gunshot wounds.

They are expected to survive, chief medical officer Janis Orlowski told reporters this afternoon during an emotional press conference.

Hundreds of SWAT and FBI rapid response units descended on the nation’s capital to deal with the situation which unfolded just before 8.30 a.m. this morning.
