Those killed in the rampage were: Michael Arnold, 59; Martin Bodrog, 54; Arthur Daniels, 51; Sylvia Frasier, 53; Kathleen Gaarde, 62; John Roger Johnson, 73; Mary Knight, 51; Frank Kohler, 50; Vishnu Pandit, 61; Kenneth Bernard Proctor, 46; Gerald L. Read, 58; and Richard Michael Ridgell, 52.
Alexis left Texas about a year ago. Authorities made a public appeal Monday for help in tracing his movements since then.
Parlave said he had been in the Washington area since about Aug. 25 and had stayed most recently at a Residence Inn in Southwest Washington. That stay began on Sept. 7.
“We don’t know what the motive is,” said D.C. Mayor Vincent C. Gray (D), who added that there was no reason to suspect terrorism.
Navy officials said that they did not have information about Alexis’s medical history or whether he was ever treated for mental illness. In both the House and Senate, committees have asked the Department of Veterans Affairs for any information on mental health treatment provided to Alexis. That department has not confirmed that Alexis received any treatment for mental health problems.
But, according to a police report, Alexis told Seattle police that he had experienced a “black-out” fueled by anger in 2004, when he allegedly shot out the tires of a construction worker’s car. Alexis also said he had been at the site of the Sept. 11, 2001, terrorist attacks, and that “those events had disturbed him,” according to the police report.
The Navy on Tuesday corrected its initial account of the circumstances under which Alexis left the service. He received an honorable discharge, effective Jan. 31, 2011, a Navy official said. On Monday, the Navy mistakenly said that Alexis had received a general discharge, a less-desirable category that would have indicated to future employers that there was something amiss with his performance.
The official clarified that the service had originally sought to kick out Alexis with a general discharge because of his pattern of misconduct while in uniform, in addition to his arrest by Texas authorities in 2010 for shooting a gun into his neighbor’s apartment. But those proceedings were moving slowly, and it was unclear whether the Navy had sufficient cause to approve a general discharge, the official said.
As a result, when Alexis applied on his own to leave the Navy in early 2011 with an honorable discharge, the service granted his request, the official said.
