Shane Tamura, the man responsible for a New York City shooting that left four dead, left a second suicide note behind in his Las Vegas home, police sources said Wednesday.

The man who stormed a Manhattan office tower with a gun worked in the surveillance department of a Las Vegas casino.

In 2022, Nevada enacted a ban on ghost guns, which are firearms without serial numbers that are sold as kits that users assemble on their own. It is one of 15 states that created legislation regulating those weapons, which law enforcement has flagged as untraceable.
