"We don't have any eyewitnesses that saw the shooting, but we'll be talking to some businesses that hopefully got it on camera," said Sgt. Robert Torres with the Houston Police Department.
Investigators say the victim, who's been identified as Inocencio Martinez-Solis, was known to carry large amounts of cash. They say Martinez-Solis, 36, just been to a check cashing business and he may have been followed by the suspect or suspects to the car wash. His wallet was missing when police found him.
Investigators say Martinez-Solis' wife is pregnant and the couple had a one-year-old child as well.
