Wichita police say a 41-year-old man is being held in the shooting deaths of his girlfriend, her adult daughter and her son-in-law at the family’s home.

Police on Tuesday identified the victims as 45-year-old Tuyet T. Huynh, her 20-year-old daughter, Trinh Pham, and Pham’s husband, 21-year-old Sean Pham. Police say the Phams’ 5-month-old child was in the basement where Trinh Pham was killed, but the baby was unharmed.

The three victims were found shot to death early Tuesday after police received an emergency call from one of the victims. Another child who lives at the home was out of town at the time.

Police say there hadn’t been any previous domestic violence cases at the residence.

The suspect is being held on capital murder charges, but hasn’t been identified.
