Killer of New York Police officer leaves suicide note

The Park Avenue gunman, Shane Tamura, who killed a New York Police Department (NYPD) officer and three others before taking his own life, left behind a suicide note.

NYPD officials Tuesday revealed that Shane left a note saying he suffered from CTE, a brain injury often linked to playing football and was targeting the NFL — but took the wrong elevator.

Shane, 27, who played high school football, took issue with the NFL in the note. He never played for the NFL.

“You can’t go against the NFL,” he wrote, police sources said. “They’ll squash you.”

New York Daily News quoted a police source as revealing that Shane’s father was a Los Angeles police officer who served between 1990 and 2008.

The suicide note, scribbled on three pages from different daily planner inserts and to-do lists, was folded neatly in his wallet as he carried out the shooting rampage Monday, cops said.

The pages had pre-printed messages on them reading “My daily affirmation” on the corner of one page and “Plan, Pause, Reflect, and Flourish” in the center of another page, which had white and pink lines.

The note was handwritten in both pen and marker, an NYPD spokesman said.

In the note, he says he wants his brain to be studied to see if he has CTE — something that will now happen as the city’s Medical Examiner prepares to conduct an autopsy.
