FBI says Navy Yard shooter thought he was controlled by radio waves

Washington: Navy Yard shooter Aaron Alexis believed he was being controlled by electromagnetic waves in the months before he killed 12 people at a Washington base on September 16, an FBI official said on Wednesday.There are no indications that Alexis, 34, was targeting anybody in the rampage at the Navy Yard in southeast Washington, said Valerie Parlave, the FBI assistant director in charge of the Washington field office.[caption id="attachment_1134237" align="alignleft" width="380"] Alexis, a government technology contractor, acted alone and was killed by police on the third floor of the Yard's Naval Sea Systems Command headquarters.
