LAS CRUCES, N.M. (AP) — A Las Cruces police officer is on standard administrative leave following a standoff that ended with the death of a 52-year-old man.

Authorities say the officer fired multiple times at Ernesto Sedillo on Monday after the man pointed a gun at him. The officer retreated and called for backup, not knowing if Sedillo was hit.

Authorities are still investigating the circumstances. A handgun and knife were found inside the sedan where Sedillo had barricaded himself.

Police Spokesman Dan Trujillo says officers had received reports of suspicious activity and a person who was possibly armed with a knife before the shooting.

Police say a flash-bang device was detonated at the scene, but there was no response from Sedillo.

Officers then approached the vehicle and found Sedillo unresponsive with at least one gunshot wound.
