Bloomington doctor Mark Dayton, 70, died Monday after being hit by a car while riding his bicycle in Lawrence County.

Bloomington doctor Mark Dayton, 70, died Monday after being hit by a car while riding his bicycle in Lawrence County, according to the Sheriff’s office.

Police said Dayton was hit by Jimmy Arthur, 26, of Mitchell, who ran a red light at the intersection of Old State Road 37 and State Road 37 in Judah. Dayton was declared dead at the scene and Arthur was uninjured.

Arthur told police the collision occurred immediately after he sneezed. Arthur said after he sneezed, he saw Dayton, hit his brakes, but was unable to stop in time, according to an accident report from the sheriff’s office.

Arthur also told police that he could not remember if the signal light was red or green.

Dayton was a cancer treatment physician who specialized in hematology and oncology at IU Health.

Police are continuing to look at evidence gathered in the investigation.

Results of a blood draw on Arthur are pending.

WFIU/WTIU News is an independent newsroom rooted in public service.

“Act Independently” is one of the basic creeds of journalism ethics, and we claim it proudly. The WFIU/WTIU News facilities are located on the campus of Indiana University, which does hold our broadcast license and contribute funding to our organization. However, our journalists and senior news leaders have full authority over journalistic decisions — what we decide to cover and how we tell our stories. We observe a clear boundary: Indiana University and RTVS administrators focus on running a strong and secure organization; WFIU/WTIU journalists focus on bringing you independent news you can trust.
