A man shot a woman in the back as she was trying to escape his car, Houston police say.

The shooting occurred under the Eastex Freeway on Homestead at around midnight Sunday.

Police told Local 2 the woman decided she no longer wanted to be with the man in his car and tried to leave.

At that point, the duo started arguing inside the car. As the woman tried to jump out of the door, the man pulled out a gun and shot her in the back, police said.

The man then took off in his car.

Investigators said the woman called a friend and waited in the friend's car for paramedics to arrive.

She was taken to the hospital in serious condition.
