The Minnesota State Patrol is asking the public for help in finding the driver of a vehicle involved in a hit-and-run crash late Saturday in Oak Park Heights that killed one bicyclist and left another critically injured.

Mai Yang, 35, died Monday from injuries she received when she and her husband, E. Xiong, 37, both of St. Paul, were struck head-on as they were riding west along a frontage road, 60th Street N., west of the intersection of Hwy. 36 and County Road 24.

Xiong remains hospitalized at Regions Hospital in St. Paul with extensive leg injuries.

“I wish we had more information about what type of vehicle may have been involved, or anything,” said Lt. Eric Roeske of the State Patrol. “But at this point, we have nothing to go on.”

It’s also unclear how much the vehicle may have been damaged, Roeske said. The crash left no debris behind to offer clues.

The couple was riding single file on the roadway about 11:50 p.m. Saturday when the vehicle, traveling east, struck both of them. Xiong has no memory of the crash, Roeske said.

“To be honest, even a minor impact with a bicyclist can result in a fatal injury,” he said.

Surveillance camera footage in the area is being studied.

Anyone who saw what happened or has additional information is asked to call authorities. The State Patrol’s east metro office number is 651-539-1151, and the Oak Park Heights Police Department can be reached at 651-439-4723.
