Killeen police are investigating an apparent murder-suicide that left three people dead Sunday afternoon.

According to a Killeen Police Department press release, officers responded to a home in the 5900 block of Cobalt Lane around 4:51 p.m. and found a 24-year-old woman lying in the driveway with a gunshot wound. The woman was transported to the Carl R. Darnall Army Medical Center, where she was later pronounced dead.

Upon entering the house, police found a man and woman, both 28, dead of apparent gunshot wounds.

According to our news partner KWTX, the incident appears to have been a murder-suicide stemming from a domestic dispute between a man and his wife. During the dispute, the man pulled a gun and shot his wife. Her sister (the woman found in the driveway) was shot while attempting to flee to safety. The man then reportedly turned the gun on himself.
