Detectives from the New York Police Department (NYPD) reported finding a second suicide note and antipsychotic medications belonging to Shane Tamura, the Manhattan gunman, in his home in Las Vegas.
The note found in Tamura’s studio apartment was revealed by investigators on Wednesday to be directed to his parents, containing a message, “I love you, mama. I’m sorry.”
Several prescription bottles for antipsychotic, antiepileptic, and anti-inflammatory drugs were found, PIX11 reported.
Also found in the home were a rifle tripod used in the shooting that killed four people and critically injured another, 100 rounds of 9mm ammunition, and an empty revolver box. The revolver was located in his car in New York.
Shane Tamura’s father, Terence Tamura, served nearly 30 years with the Los Angeles Police Department (LAPD), officials said.
“The LAPD can confirm that Police Officer III Terence Tamura retired in good standing on August 5, 2017,” an LAPD representative informed NBC 4 Los Angeles.
Shane Tamura, who succumbed to self-inflicted gunshot wounds after the attack at the building housing Blackstone and the NFL headquarters, also carried a three-page suicide note on him.
The 27-year-old attributed his mental health struggles to Chronic Traumatic Encephalopathy (CTE), a brain condition often associated with repeated head injuries seen in football players after concussions.
The note referenced the NFL and reportedly “asked for his brain to be studied,” according to ABC News.
“He appeared to have blamed the NFL for his injury,” New York City Mayor Eric Adams said.
An NFL employee was badly injured in the shooting but is expected to survive, ESPN reported.
Tamura played high school football in California while his father worked for LAPD, with his former coach wondering if he could have done anything to prevent the tragedy a decade ago.
“Total shock, total shock,” former football coach Walter Roby told NBC 4. “Just to see someone you’re affiliated with or someone that you know or coach, it’s tough. It’s really tough to see in that light.”
“It reminds you of the word, 99 sheep and 1 gets away, you try to really look at yourself,” he said. “Could there have been more than I could have done to help him?”
Tamura also mentioned his supervisor at the security guard job he worked at a Las Vegas casino in the note found at the scene.
“I’m sorry, Rick,” the paper found in the shooter’s wallet stated.
Rick, whose last name is being withheld, sold Tamura the AR-15 used in the shooting as well as the BMW he drove from Nevada to New York in, police confirmed.
He has not been charged with any crime as of Friday.
