An anonymous call early Monday led police to a possible murder scene at a Santa Ana apartment, authorities said.
Police responded around 3 a.m. to the 200 block of South Birch Street and saw a woman through the window bleeding. Officers forced their way inside the apartment, and the woman was pronounced dead at the scene.
A man was also home at the time and detained for questioning.
The woman was not immediately identified. It was unclear how she died.
