A 54-year-old man was shot and killed while driving on Central Expressway during a road-rage incident Monday.

That happened less than 48 hours after two people died in a five-car pileup in which three people were arrested for drunk driving.

In the Monday incident, Dallas police were called at about 10 p.m. to a major accident on northbound Central Expressway near the Woodall Rogers ramp. They found Carl Edmiston with a gunshot wound inside his vehicle; he was taken to a hospital and pronounced dead. Edmiston’s 17-year-old son was injured in the leg and taken to the hospital with non life threatening injuries.

Police say the shooter was involved in a road-rage incident with the victim prior to killing him. The shooter continued northbound on Central in a dark-colored vehicle.

Anyone with information on that crime is asked to call Detective Chad Murphy at 214.671.3679 or chad.murphy@dallascityhall.com.

The drunk-driving pileup happened just after bars closed, at about 2:20 a.m. Sunday, in southbound lanes near the Fitzhugh exit.

The passenger and driver of one car, 27-year-old Melissa Aguilar and 31-year-old Sergio Moriel, were killed.

Marsalis Brown, 31, was arrested and charged with two counts of intoxication manslaughter in their deaths. Two other drivers — 28-year-old Jose Salazar-Reza and 24-year-old Grayson Tsai Meu Chong — were arrested and charged with DWI.
