Man shot, killed by ex-girlfriend's new boyfriend outside Denny's in SE Houston

Police say an argument between two exes resulted in a woman's new beau allegedly killing her former boyfriend outside a Denny's parking lot in southeast Houston.

It happened around 1:30 a.m. at the Denny's off of Woodridge Drive near the Gulf Freeway when authorities were called for reports of a shooting. Based on preliminary findings, police say a man and woman, believed to be exes, met at the Denny's when they got into an argument.

It's unclear what the argument was, but officials say the surveillance camera from the restaurant shows the ex-boyfriend seeming irate and just yelling. At some point, the woman's new boyfriend showed up, and an argument escalated in the parking lot. That's when police say the new beau shot the ex-boyfriend one time, killing him. 

All three individuals were not identified by authorities, but we're told the shooter was detained as a result.
