Cops find note in NYC shooter Shane Tamura’s Las Vegas apartment revealing he felt like a ‘disappointment’ to his parents

Investigators found a note left by Midtown mass shooter Shane Tamura at his Nevada apartment saying he felt like a “disappointment” to his parents — including his father, a retired cop, sources told The Post.

The missive read something like: “When I look into you and dad’s eyes, I see complete disappointment,” the sources said.

Tamura, 27, lived in Las Vegas and was most recently employed as a casino security guard.

His dad was an 18-year veteran of the Los Angeles Police Department, sources said.

Tamura drove cross country, getting to Manhattan just before he stormed into the Park Avenue skyscraper Monday evening with an AR-style rifle.

He double-parked his BMW in front of the building, which houses the headquarters of the NFL, his intended target for the rampage.

Tamura shot and killed two civilians and an NYPD officer in the lobby, and wounded another, before riding the elevator to the 33rd floor where he killed another office worker before turning the gun on himself.

Upon searching his body, cops found a rambling note in his wallet blaming the NFL for his apparent CTE — a degenerative brain disease brought on by repeated blows to the head — despite never actually playing in the league.
