GLENDALE, Ariz. (AP) — Authorities have released the names of three men who were found dead in a Glendale house from apparent drug overdoses.

Glendale police say 36-year-old Michael Smith rented the house and 44-year-old Heath Spencer and 37-year-old Angel Cruz were his acquaintances.

Police say officers were called to the house 6:30 a.m. Sunday and drugs were found near the bodies.

Detectives have confirmed that the three men ingested drugs prior to their deaths and a quantity of fentanyl and methamphetamine was found in the home.

The substances have been sent to a lab for analysis.

Authorities say the cause and manner of death for the three men will be determined by the Maricopa County medical examiner after toxicology tests are completed.
