A woman was found dead in a Santa Ana apartment on early Monday, and a man who was with her at the time has been detained for questioning, police said.
About 3 a.m. Santa Ana police responded to a call of a woman who was hurt in the 200 block of South Birch Street.
Responding officers saw the woman bleeding on the floor of the apartment from the outside window and a man was next to her. Officers had to force their way into the home to check on the woman, Cpl. Anthony Bertagna told KTLA.
The woman was declared dead at the scene, but it is unclear how she died.
She has not been identified, but police described her as being in her 50s.
The man, described as being in his late 30s, was detained for questioning. It is unclear if he was the person who called police.
A second man was also detained and interviewed shortly after, but Bertagna said both were being treated as persons of interest at this point, not suspects.
Investigators at the scene Monday afternoon were waiting for a search warrant to go inside the house and gather evidence, Bertagna said.
He added that police are familiar with the apartment and have visited on a "regular basis" for narcotic activity and disturbances.
A hazardous materials team was also called to the scene after police discovered something that caused them concern, described as being some sort of lab. The building was later deemed safe to enter, but authorities did not disclose what had been found.
