(CBS News) WASHINGTON — Sources say Aaron Alexis left behind two short phrases on the side of the shotgun used in the Washington Navy Yard massacre.
One of the messages scratched into the gun’s metal reads, “Better off this way.” The other is more cryptic: “My ELF weapon.”
Investigators don’t know what the etchings mean. “ELF” might be a reference to “extremely low frequency” radio waves used by the Navy to communicate with submarines.
It also may relate to a strange incident which happened six weeks ago in Newport, R.I.
Alexis complained to police that stalkers were using a microwave-type machine to send “vibrations into his body.” Newport investigators took a report and gave it to local Navy police. It apparently was never passed up the chain of command.
After the Newport episode, Alexis sought help at two hospitals operated by the Department of Veterans Affairs.
Government records show that on Aug. 23, Alexis visited a VA emergency room in Providence, complaining of insomnia. He received medication to help him sleep. Then five days later, on Aug. 28, he refilled the sleep aid prescription at a VA medical center in Washington.
