The brain of depraved shooter Shane Tamura could possibly be tested for chronic traumatic encephalopathy during an examination of his body, Mayor Eric Adams said Tuesday.

Shane Tamura — who fatally shot four people at a Midtown East office building — said in a suicide note he believed he suffered from CTE and requested his brain be studied.

New York City police detectives searched a studio apartment in Las Vegas that belonged to the suspected gunman in Monday's mass shooting at a Midtown Manhattan.
