PHOENIX (AP) -- Authorities say a Phoenix woman has been fatally shot and her common-law husband is in custody.
Phoenix police say 33-year-old Carlos Tino Villareal has been booked into the Maricopa County Jail on suspicion of second-degree murder.
Officers responded to a shooting call at a west Phoenix apartment complex about noon Tuesday and found 32-year-old Christina Alvarez wounded.
Villareal told police it was an accident that occurred while the two were in a bedroom. The couple's three children were in another room of the apartment at the time.
Alvarez was transported to a Phoenix hospital, where she later died from injuries.
Police say Villareal was detained for questioning and detectives learned Alvarez was shot after she and Villareal got into an argument. It's unclear whether he has a lawyer yet.
