More information is emerging about Alexis' mental state prior to the Navy Yard shooting.
Federal investigators are learning more about the man who shot and killed 12 people at the Washington Navy Yard and his state of mind just weeks before Monday's shooting.
A month before he entered Building 197, Aaron Alexis told police in Rhode Island that people were talking to him through the walls and ceilings of his hotel rooms, according to the Associated Press. He also said they were sending microwave transmissions to deprive him of sleep.
While the account, contained in an August 7 report from police in Newport, R.I., gives further insight into Alexis’ mental state before this week’s shooting, it provides investigators no clue about motive.
“We continue to conduct interviews, exploit digital media, and rundown every lead we can to piece together his recent movements,and determine the motive behind his attack," said FBI Assistant Director Valerie Parlave.
Newport police alerted the Rhode Island naval station where he worked about the August incident and sent a copy of the statement. A spokesperson for the station had no comment on the report.
Alexis had various run-ins with police in recent years, including two gun-related incidents—one in 2004 in Seattle, Wa. and one in 2010 in Ft. Worth, Tex.
