Las Vegas Officer's Tragic Death After Shocking Gun Battle

The slain officer was also a Marine veteran.

A 30-year-old police officer died after Las Vegas law enforcement had a gun battle with an "erratic" person waving a gun, authorities said.

Just before 4 p.m. Tuesday, authorities received multiple reports of a person walking near an intersection who was "acting erratically while waving a gun in the air," Las Vegas Metropolitan Police Capt. Adam Seely told reporters.
