Police said it happened at about 11 p.m. when there were three people inside a car driving down South Post Oak and 610.
At some point, police said the front and backseat passengers got into an argument and shots were fired.
"It was entirely within the car. It was the passengers, there was an argument between them that lead to the shooting," said Cmdr. Isaac Duplechain with the Houston Police Department.
A woman who was driving was not hurt.
Police said they are speaking with her to learn more about what led up to the shooting. Officers also said they recovered several weapons.
