Neglecting mental instability report of Navy Yard shooter may have led to ghastly incident

A Rhode Island cop had reported to the naval station police about the mental instability of Navy Yard shooter Aaron Alexis in August, but the federal agency's negligence towards his behavior may have led to Monday's incident.

The Newport officer, whose name was not disclosed, said he was sent to a local hotel on August 7 to check Alexis's claim that three suspicious people were following him from the airport and were sending vibrations into his body to keep him awake, which made the officer believe that he was mentally unstable, Fox News reports.

According to the police report, Alexis said to the cops that he was a naval contractor and was doubtful that two black males and one black female were allegedly using a microwave machine to keep him awake as he heard voices through a wall of his hotel room.

The officer said that when he contacted on-duty Naval Station Police official, he said that they would follow up on the issue and determine if Alexis was a naval base contractor or not.

Alexis was working as an IT subcontractor with Hewlett Packard and required a secret federal security clearance when he was re-hired in July.

According to the report, Alexis had his clearance renewed just two months before Monday's shooting at the Navy Yard that killed 12 and injured a dozen people, before he was killed in the shootout.
