Video released Wednesday by the Edinburg Police Department shows the moments before a fatal shooting at Jaguars — leaving a 29-year-old McAllen man dead and six others injured.

Investigators released surveillance footage from Jaguars, the all-nude strip club on State Highway 107. Police have said they believe a gang-related dispute prompted the shooting Sunday morning.

As CBS 4 News previously reported:

At 4:40 a.m., police responded to Jaguars, according to new information released Monday by the Edinburg Police Department.
Investigators believe club management ejected two men from the building. They returned with a weapon and started firing at patrons.
The shooting killed 29-year-old Jaxmany Jazan Montes of McAllen and left six other men injured.
The two men — described only as Hispanic males — fled in a light-colored sedan.

The video shows bouncers frisking four men as they enter the strip club with three women. Later, the video shows bouncers asking several men to leave the premises.

Investigators want to speak with all four men shown in the video.

Police ask anyone with information about the shooting to call (956) 383-TIPS.
