The security video is stark, but authorities in Springfield, Missouri, are hoping there are enough details for someone to provide the names of members of a black gang who attacked and bludgeoned two victims recently.
Although the gang members caused serious injuries, they didn't leave anything that has identified them.
The video shows the six gang members coming up from behind and taking down a man who was walking along with a woman. She's attacked, too, but not in the initial slugfest.
For half a minute, the beating continues. First one attacker bails, then a second and then two more.
After a final round of kicking and slugging, the last two gang members flee.
The Springfield Police Department and the local Crime Stoppers program released the video of the violent assault in the city's downtown to help identify suspects.
The attack occurred just after 12 a.m., Friday, Aug. 22, at 318 S. South Ave.
"The victims sustained serious injuries after they were assaulted by multiple black males, including the one dressed in black clothing and red shoes," the video said.
Anyone with information is asked to contact city officials.
Colin Flaherty, author of "'White Girl Bleed A Lot': The Return of Racial Violence to America and How the Media Ignore It,"Â documents a surging number of black mob attacks on white victims across the nation.
The mob attacks have include random targeting of attacking visitors to their neighborhoods, people walking down streets near their own homes, and people at public events such as festivals and fairs. Among the attacks are the "Knockout Game," in which an attacker aims to hit someone in the head hard enough to knock him out.
The attacks have resulted in multiple fatalities.
