MESA, Ariz. — A murder-suicide investigation is underway after three people were found dead inside a Mesa apartment on Monday, the Mesa Police Department said. 

The bodies were found just after 7:30 p.m. near Broadway and Alma School roads after police received a call about a possible shooting. Officers arrived at the scene to find 46-year-old Aide Popoca, her 21-year-old son and her 14-year-old daughter all dead. The bodies were each found in different rooms of the house.

Early evidence suggests the woman's son, identified as Rafael Popoca, killed her and his sister, Ashley Popoca, before shooting himself, detectives said.

"It is very early in the investigation and details may change as the investigation continues," police said.

This is a developing story; additional detail will be added as they become available.
