Police say they were called a little after 2:15 a.m. to a bar in the 13700 block of Westheimer where they found a man shot to death. Preliminary information is that a patron at the bar got into an argument with an armed security guard. 

It's unclear what the argument was about, however, police say the patron went to his car, grabbed a gun, and went back to the security guard. That's when the guard opened fire on the man, killing him. 

The victim's identity was not released but was said to be 33-years-old.
