MESA, Ariz. — Mesa homicide detectives are investigating a shooting incident that killed two people and injured one on Saturday night.
Officers responded to a residence near Main Street and Gilbert Road, where they found one gunshot victim.
The injured person was transported to the hospital.
Upon further investigation, officers found two deceased victims inside the residence, police said.
