TULSA, Oklahoma - Police are looking for a gunman who opened fire on a security guard and a man at a Tulsa QuikTrip early Monday.

It happened at the store in the 2700 block of East Admiral Place just before 1 a.m.

Police say the two people who were fired at had to duck behind a trash can for cover.

Officers got the call that four to five rounds had been fired in front of the QT and the shooter was on the run.  The shooter was identified as Robert Hogard, and the victim says his son's mother has been abused by Hogard.

Police were at the QuikTrip earlier overnight and after they left, they say that is when Hogard showed up, got into an argument with the victim, and they say he opened fire on the victim and a security guard.

Bullets hit the building and shattered glass, but missed hitting any people.

Police say Hogard ran off.  

They ask if you know where Robert Hogard is to call Crime Stoppers at 918-596-COPS.
