This news at the U.S. Capitol comes just weeks after a mass shooting occurred in Maine. Robert Card is the primary suspect in the mass shooting that took place in Lewiston last month. He was found dead 48 hours later after a massive manhunt took place. He was found from a self-inflicted gunshot wound, police confirmed.

Prior to discovering Mr. Card’s body, the FBI located a note in a home, which was believed to be owned by Mr. Card.

Maine Department of Public Safety Commissioner Mike Sauschuck gave more details regarding the note found in Mr. Card’s home, explaining that it was a paper-style note addressed to a loved one. The note reportedly stated, “This is the passcode for my phone; this is the bank account number.”

Although Sauschuck did not describe it as an explicit suicide note, he did state that the note indicated that Mr. Card would not be around for much longer

Robert Card was committed to a mental hospital involuntarily just months before the tragic events.

It was previously reported that the 40-year-old army veteran stated he was hearing voices, and had allegedly threatened to shoot up the National Guard base in Saco. Reports also stated he was then committed to a mental health facility for two weeks this summer.

However, Mr. Card was still able to legally purchase firearms just days before the Maine mass shootings occurred.

“We must protect our freedom," he added.
