Surveillance video captured the suspect getting out of his car and approaching the driver of a white pickup truck.
"It appears that when he backed up that he came too close to this guy's vehicle," said Harris County Precinct 4 Constable Mark Hermann when asked what may have triggered the altercation during a press conference on Tuesday.
Deputies say the aggressor then got into his car, caught up to the victim and shot him.
The incident was one of two road rage shootings in the greater Houston area on Monday, both of which were a trigger for Suzie Woodard, who lost her daughter in a road rage shooting in February.
In the early morning hours of Feb. 6, police said 35-year old Stacey Berghoff was parked on Rannie Road in northwest Houston when a man confronted her about where she was parked. Things escalated to a physical fight and Woodard said her daughter was punched in the face.
According to police, Berghoff pulled a knife and stabbed the man before getting in her car with a friend and leaving.
The man followed the two friends and shot through the car, killing Berghoff.
"She was 35," said the grieving mother. "I expected her to live as old as I, if not longer."
Investigators have since released a sketch of the suspected shooter in Berghoff's case in hopes that someone from the public can help them identify him.
