Vehicle strikes, kills ex-fighter Ryan Jimmo after parking-lot conflict

EDMONTON, Alberta -- Former UFC fighter Ryan Jimmo was fatally injured early Sunday morning following an altercation in a parking lot in Edmonton, police said.

They believe Jimmo, 34, had approached the driver of a vehicle and was walking back to his own car when he was struck by a vehicle, which then fled the scene.

Jimmo, a Canadian, was pronounced dead in hospital. Police were still looking for the suspect vehicle, described as a dark-colored, customized, older-model pickup truck.

Known as "The Big Deal," Jimmo went 19-5 in his mixed martial arts career, with a 3-4 record in seven UFC fights.

Fighting as a light heavyweight in his July 2012 debut, he tied the record for the organization's fastest knockout when he dispatched Anthony Perosh in just seven seconds. Jimmo celebrated by doing a robot dance, followed by the splits in the middle of the cage.

His death prompted a social media outpouring from the MMA community. UFC president Dana White tweeted a photo of Jimmo flexing on stage at an unspecified event with the caption "RIP Ryan Jimmo."
