Manhattan Gunman's Motive Linked to CTE, Concealed Carry Permit

Investigation into Manhattan Shooting

• 🎯 The gunman, Shane Tamura from Las Vegas, entered a Manhattan office building armed with a high-powered rifle and died by suicide at the scene.
• 💔 One of the four victims was an NYPD officer who was killed while protecting New Yorkers.

Suspect's Note and Potential Motive

• 📝 A note found at the scene indicated the suspect believed he had CTE (Chronic Traumatic Encephalopathy) and blamed the NFL for concealing its dangers for profit.
• 🏢 The suspect's intended target may have been the NFL headquarters, located in the building, but he mistakenly went to the wrong floor, leading to shootings at Ruden Management and other offices.
• ✈️ Tamura traveled from Las Vegas over three days, with stops in Colorado, Arkansas, and Iowa, before arriving in New Jersey two hours before the shooting.

Concealed Carry Permit and Mental Health History

• 🔑 Tamura obtained a concealed firearms permit in 2022 with a clean record prior to any police interaction.
