Kevin Champion was shot at point-blank range on Aug. 15, 2010 after closing one of his liquor stores in Gary, Ind.
The family of Kevin Champion says they still have no idea who, nor why, someone would shoot their loved one at point-blank range.
"It's cold-blooded. You don't do this to another human being," said the 41-year old's brother, Andre Champion.
The family owns two liquor stores in Gary, Ind., both named Champ's Liquors. They've been in business in Gary for about 35 years.
Kevin Champion had finished closing one store at 2:45 a.m. Sunday, and was in the parking lot of the second store -- preparing to close-up there -- when a man runs up to the open window of the SUV and starts firing.
The gunman then reaches in and grabs something from the vehicle before running away.
The entire incident was captured on the store's surveillance camera.
Andre Champion is hoping the public will help catch his brothers killer.
"We just want who ever may know something to call police," he said. "Because it could've been anybody."
Detective James Bond said the suspect is a black male between 5-foot, 9 and 11 inches tall with a medium build. The video released by police shows the gunman in a light-colored shirt and short hair.
