WASHINGTON - The FBI has released video of Navy Yard shooter Aaron Alexis. The chilling 30 second video shows him entering a building, producing a shotgun and making his way down several hallways. (Watch the video below)
Valerie Parlave, head of the FBI's field office in Washington, says there is no indication that the Navy Yard shooter targeted any specific individuals when he opened fire inside a building, killing 12 people.
Parlave said during a Wednesday news conference that investigators are continuing to explore the background and motivations of 34-year-old Aaron Alexis. However, she says Alexis had a well-documented history of mental health issues.
Parlave says Alexis held a delusional belief that he was being controlled by extremely low frequency waves, or ELF waves. Alexis had written "my ELF weapon" on a shotgun he used in the rampage.
Alexis, a former Navy reservist and IT contractor, was killed in a shootout with police.
