The gunman in Monday’s mass shooting in Midtown had bottles of antipsychotic medication in his Las Vegas studio apartment, police said after executing a search warrant.

Police said Shane Tamura, 27, killed four people Monday, including an NYPD officer, and critically wounded a fifth. The shooting took place at a Park Avenue office tower that housed the National Football League's headquarters. Police say Tamura shot himself afterward.

Officials said a suicide note found in Tamura’s wallet blamed his mental health struggles on chronic traumatic encephalopathy, or CTE, a brain disease linked to repeated head trauma and often associated with professional football players.

Authorities said they found a second suicide note, numerous rounds of ammunition and a tripod for the rifle used in the shooting inside Tamura's apartment.

Investigators also found several prescription drug bottles, including an anti-inflammatory, an anti-epileptic drug and an antipsychotic medication. Police did not identify the specific drugs.

Police said the rifle used in the shooting was sold to Tamura by his supervisor at the Horseshoe Casino in Las Vegas.

Officials had previously said Tamura assembled the rifle himself from various parts. On Wednesday, they clarified that Tamura purchased the rifle fully assembled. They said the supervisor bought the weapon legally, but did not confirm whether the sale to Tamura complied with the law.

Police said the supervisor also sold the BMW to Tamura, which he used to drive across the country. The supervisor has not been charged with a crime. Police also recovered a revolver from the crime scene.

Police said investigators with the NYPD’s Joint Firearms Task Force also searched Tamura's work locker at the Horseshoe Casino and are awaiting a judge’s permission to search his phone and computer.

Officials also found a note in Tamura’s apartment written to his mother, which read, “ When I look into you and dad's eyes, all I see is disappointment. I love you, mama. I'm sorry.”
