San Jose police released graphic surveillance video of a triple homicide at the Mexicalo Club earlier this year.
Police said they are hoping someone will help them identify the man seen in the video wearing a bullet-proof vest.
Police said the men who busted into the club on Jan. 8 intended to kidnap the owner because of a drug debt. He survived, but three others died.
Warning: the video, which is separated into three parts, is graphic in nature.
