According to Executive Chief Matt Slinkard with the Houston Police Department, the shooting occurred on at the Shell gas station, located on the 14000 block of U.S. Highway 59.
Authorities said the whole incident was believed to have begun the day prior as a potential domestic violence incident where Melvin Porter held an ex-girlfriend at gunpoint. The ex-girlfriend was able to separate from him the same day.
The incident continued into Tuesday where Porter tried to make contact with the ex-girlfriend again, but she refused, officials said.
That's when, authorities said, Porter went to the ex-girlfriend's place of business in the 400 block of Benmar Drive in Houston, and kidnapped one of the ex-girlfriend's co-workers at gunpoint in an effort to get in contact with the ex-girlfriend.
Porter later made contact with the ex-girlfriend saying he had one of her co-workers and she was being held hostage.
Slinkard said they believe the ex-girlfriend convinced Porter to stop and let her go to the bathroom, and he agreed.
After they exited the inside of the store, the ex-girlfriend was sitting in the driver's side of the vehicle, while Porter was sitting in the passenger side, officers blocked the suspect vehicle from leaving the area.
SWAT officers, who were arriving at the scene, were giving verbal commands to get the ex-girlfriend out of the vehicle safely, Slinkard said.
As that was occurring, officers who were watching Porter, saw he was reaching for what they believe was a weapon. That's when, Slinkard said, four officers, one Houston Police Department Sergeant and three Houston Police Officers, fired their weapons at Porter when he ignored verbal commands.
Officials stated Porter was rendered first aid, but was pronounced dead at the scene.
The officers involved in the incident were uninjured and later identified as Sergeant S. Duvall and Officers D. Inocencio, J. Luna, and A. Lopez, with the North Belt Division and were sworn in on March 2009, July 2018, May 2017, and March 2017, respectively.
Officials said the ex-girlfriend was unharmed in the incident. No other injuries were reported.
