West Valley police are investigating a possible homicide after a woman was found dead in her apartment Sunday morning.

Eamiana Castillo, 57, was found at about 10 a.m. when her son went to visit her at her home near 4000 S. Redwood Road. The woman likely died Saturday or early Sunday, police said.

"We're investigating it as a homicide," said West Valley Police Lt. Lamonte Cox. "There are some things that are very suspicious."

Police declined to discuss specifics of the death or the investigation Sunday night.

Investigators do not have any suspects, Cox said. Anyone with information about Castillo or her death is urged to contact police.
