How'd He Get the Carry Permit: Manhattan Shooter Had Documented Mental Health Issues

A lone gunman walked into a midtown Manhattan office building Monday afternoon and opened fire, killing four people – including an NYPD officer – before turning the gun on himself. 

Speaking at a press conference later Monday, NYC Police Commissioner Jessica Tisch identified the shooter as Shane Tamura, a 27-year-old Las Vegas resident with a history of mental health issues. 

Tisch said Tamura had driven across state lines, with his vehicle having been seen as recently as 4:24 p.m. Monday in Columbia, New Jersey, not long before he unleashed a barrage of gunfire. 

Officers found a rifle case with rounds, a loaded revolver, ammunition and magazines, a backpack, and medication prescribed to Tamura, Tisch said.
