A July 8 shooting outside an apartment complex in Lake Havasu City is under investigation. Lake Havasu Police sergeant Kirk Cesena said officers responded to the incident in the 2100 block of Industrial Boulevard at about 10:00 p.m.

Cesena said it is not clear what triggered the altercation that escalated into a shooting. And he said the combatants apparently did not know one another.

Wounded and transported to Havasu Regional Medical center for treatment and surgery was Christopher Monsouir, 32. The gunman was identified as Christopher Irons, 25.

Irons was not arrested and the county attorney’s office will review the case investigation before charging decisions are made.
