DALLAS (WFAA) -- Dallas police are investigating after an off-duty officer shot and killed a suspect in the murder of another person at the intersection of North Central Expressway and Midpark Road early Wednesday morning.
According to police and witnesses, the officer was working a security job at a Walmart store when there was a commotion at the gas station in the parking lot just before 1 a.m. between people in two vehicles.
One shot was fired, police say, and one of the vehicles crashed into parked cars. A man was discovered dead inside.
The suspect took off and the officer chased him into the parking lot of a Denny's restaurant across the street.
The officer says he spotted a gun and told the suspect to put it down, but he didn't listen and took off again, eventually crashing into cars at the Denny's restaurant.
Police say the officer opened fire when he felt his safety was at risk. The gunman was pronounced dead.
Dallas PD spokesman Kevin Wetherington tweeted confirmation that police were "investigating an officer-involved shooting."
Department spokeswoman Monica Cordova added that no officers were injured and "one suspect deceased" at 13700 North Central Expressway.
Additional details were not immediately available.
Dallas police have now been involved in at least six deadly shooting incidents this month.
