It's said that revenge is a dish best served cold.

Well, we're not sure about the revenge part, but someone served up a body Tuesday night outside of Danny's Food Mart on Collingsworth in northeast Houston. This was the second murder outside of a convenience store in a week.

Police got a call about a shooting at 3814 Collingsworth a little before 8 p.m. But by the time they arrived, the damage had been done. Witnesses told police that someone wearing a mask walked up to a man just outside the grocery store and shot him in the head, authorities say. The masked man then ran away.

The 43-year-old victim, whose name is being withheld, was rushed to Ben Taub General Hospital, where doctors declared the man brain dead, police say. Investigators do not have a good description of the shooter and the motive remains unclear.

Anyone with information about this case can call Crime Stoppers at 713-222-TIPS.
