The New York Times – The gunman who killed a police officer and three other people at a Midtown Manhattan office building on Monday bought his AR-15-style rifle for $1,400 from the man who supervised him at his job at the Horseshoe Casino in Las Vegas, New York police officials said on Wednesday.
The police did not say during their briefing whether the sale of the weapon to the gunman, Shane Devon Tamura, 27, was illegal, but said the seller had been cooperating with investigators and was not being charged in New York.
Mr. Tamura left a suicide note in his Las Vegas studio apartment, where investigators also found anti-psychotic prescription medication, the police told reporters at the briefing.
“Back in his Las Vegas apartment, investigators found various pills prescribed to Mr. Tamura, including anti-epileptic and anti-inflammatory medications.”
Mr. Tamura’s note, which was read to reporters, was addressed to his parents.
“When I look into you and Dad’s eyes, all I see is disappointment,” he wrote. “I love you Mama. I’m sorry.”
The new details released on Wednesday emerged as New York Police Department investigators remained in Las Vegas, talking to Mr. Tamura’s co-workers, friends and family members. They also planned to search Mr. Tamura’s locker at the Horseshoe Casino.
The officers were seeking to learn more about Mr. Tamura’s mental health and what had led him to New York City on Monday afternoon, when he strode into the office building and began shooting.
Mr. Tamura’s boss also sold him the black BMW that he drove from Las Vegas to New York before the attack.
Police Commissioner Jessica Tisch said that Mr. Tamura had been scheduled to work on Sunday, but never showed up. By that time, he had already driven through Colorado and was on his way to New York City …
