Police were searching for three suspects in their late teens to early 20s who were spotted driving a silver or white four-door car, Fox 26 reported.

Two men tried to carjack Pedro Aguilar, 47, outside of his north Harris County apartment on Saturday night as Aguilar was trying to park his car. Aguilar’s wife and 10-year-old daughter were standing nearby helping him park.

Police said one of the suspects ordered Aguilar out of the car and pistol-whipped him when they believed he was taking too much time. The two carjackers then got in the car but found they were unable to operate stick shift.

Before escaping, one of the men shot Aguilar in the chest, killing him.

A third person was driving the sedan the suspects used to escape.

Son Kevin Aguilar told Click2Houston his dad was “The best person, my inspiration, my everything.”

He added, “He was always happy. He’d say, ‘I want the best for you.’ It’s difficult.”
