In a case of murder-suicide in Houston, a man fatally shot his pregnant ex-girlfriend, wounded her family before killing himself.

Houston Police Department Chief Art Acevedo said the suspect, identified as Kendrick Thomas, first forced his way into a home in the 6900 block of Landor Street near Tipton Street on Wednesday (May 20) morning and shot his ex-girlfriend, who was seven months pregnant. He also shot her sister and mother. Thomas then drove to his ex-girlfriend’s current boyfriend’s home and shot him twice.

The suspect was then found hiding in a truck Wednesday afternoon. Following a 10-minute standoff between the suspect and the police, Thomas killed himself.

Police called it a case of "domestic violence turned deadly." The pregnant woman, identified as 24-year-old Cody John, did not survive. The woman’s mother and sister were being treated at a hospital. They were both serious but in stable condition. The pregnant woman’s boyfriend, James Bass, was also in a stable condition.

Meanwhile, speaking to local daily KPRC 2, Tarnika Wiser, a neighbor, said the mother, who was in her 40s, and her daughters lived in the house.

“She is very excited. That’ll be her first baby. Her mom was real excited because that was about to be her first grandbaby,” Wiser said, adding that the deceased woman, who was living with her boyfriend, had recently moved back in with her family.

“She wasn’t hiding, she was basically coming here because she was done with it and she needed to be around her loving parent, you know, in a safe house, period,” Wiser said.

Investigation into the incident was ongoing.

The incident comes days after a woman fatally shot her 8-year-old daughter before killing herself at their southern Oak Cliff home in Dallas. The woman and her husband got into an argument during which she opened fire on him. The husband ran out of the home and called 911. When the officers entered the home, they found the woman and the girl dead. A 12-year-old boy, who was inside the home when the shooting took place, escaped unhurt.
