Matthew Tynes, 23, of Grand Prairie was driving his Chevrolet Camaro the wrong way on Garland Avenue when he hit Dale Anderson, 22, of Garland head-on.
Anderson was taken to Presbyterian Hospital of Dallas, where he later died.
"One of those crashes that's very preventable," said Joe Harn of the Garland Police Department. "Number one -- don't drink and drive."
Tynes has been charged with intoxication manslaughter. It's unknown what his blood alcohol level was at the time of the crash.
Tynes has no criminal history.
Anderson's loved ones want to know why Tynes chose to get behind the wheel.
"You could've slept in your car; you could've had somebody get you," said Anderson's former girlfriend, Nashanda Washington-Green. "You decided to drive and hit him head on."
Washington-Green met Anderson at a skating rink, and they dated for three years. Their daughter, Jordyn, turns 2 next month.
Anderson worked security in downtown Dallas. He graduated from Garland High School, where he played football. Many friends tweeted they would miss his smile and dry wit.
"He wasn't in the streets, he wasn't into drugs; he was happy," said Washington-Green. "We had fun."
She says Anderson enjoyed riding motorcycles and the one he drove Monday night was new.
"I hope justice will be served," said Washington-Green. "You spend time. You rot in there. You took somebody's life and I hope you feel bad about it."
