**Manhattan Massacre: Gunman’s Mental Health History and Private Gun Sale Under Scrutiny After Deadly Shooting**

**NEW YORK, NY -** A mass shooting in a Midtown Manhattan office building on Monday has left four people dead and one injured, marking the deadliest such event in New York City in a quarter-century. The shooter, identified as Shane Devon Tamura, 27, of Las Vegas, took his own life after the attack.

Authorities are now investigating how Tamura, who had a documented history of mental health issues, was able to legally possess firearms and transport them across state lines undetected. Tamura possessed a concealed carry permit from Nevada and had been placed on psychiatric hold twice in recent years, raising questions about the effectiveness of background checks and the sharing of mental health information with the federal government.

The AR-15 style rifle used in the shooting was legally purchased by Tamura’s supervisor at his job in Vegas, who then sold it to him in a private sale. Authorities are investigating if the private sale followed Nevada state law which requires background checks.

The shooting has reignited the debate over gun control, particularly concerning private sales and the “gun show loophole.” Governor Kathy Hochul has called for a national ban on assault weapons and criticized Nevada’s gun laws as being too lax.

Victims included an NYPD officer, a security guard, a Blackstone executive and a Cornell grad. Authorities are working to piece together a motive and timeline of events.
