The Dakota County Sheriff's Office is offering a $1,000 reward for information that may help identify the hit-and-run driver who fled the scene after critically injuring a seasoned cyclist on Tuesday.

Bryan W. Joas, 45, of Eagan, was run over from behind while bicycling east on 250th Street W. at Highview Avenue in Eureka Township around 5:45 p.m. Tuesday, authorities said. Joas was flown by helicopter to North Memorial Medical Center in Robbinsdale, where he was in critical but stable condition, said Sheriff Tim Leslie.

Leslie said Joas was making a meandering ride home from his job in Burnsville, which he occasionally does. Sometimes these rides run 50 to 75 miles, his wife Shauna told the sheriff.

Joas suffered several internal injuries, a broken back, hip and ribs. But a helmet spared him from any head injuries.

Authorities initially requested the public's help in finding a white pickup truck but they no longer suspect that type of vehicle was involved. The driver of another make and model may be responsible and have front-end damage.

Anyone with information is asked to call 651-438-4721.
