Four people have died after a shooting in Casa Grande, Arizona.

Police are investigating the homicide, but say there is no active shooter as the person of interest is in custody.

Neighbours told ABC15 they heard multiple gunshots and a woman screaming after two men went into an apartment complex. They then called 911 after the men fled from the building.

Schools in the area were placed on lockdown as part of precautions.
