Two men were found dead in their home Saturday, and Phoenix police said they suspect murder-suicide.

They spoke to a caller who stated her boyfriend was found shot inside the home and possibly heard another shot also coming from inside the home.

After securing the area, officers entered the home, finding 44-year-old Ryan Liming dead from a gunshot wound and James Quinn, 55, dead from a self-inflicted gunshot wound.

Detectives investigated and “believe there was a dispute between Liming and Quinn earlier in the evening. Quinn later shot and killed Liming then turned the gun on himself sometime after,” according to a Phoenix Police Department release.

 Detectives continue to process the evidence as the case remains active.
