Deputies with the Raleigh County Sheriff’s Department confirmed the body of Mark Andrew Lilly, 50, of Fayetteville, was located on Grandview Road after 9 a.m. Saturday.

A medical issue may have caused his death, investigators said.

Lilly, described as an “avid road bicyclist,” was out on a ride at the time of his death after parking his vehicle at Raleigh County Memorial Airport where it was discovered Friday.

Surveillance video showed Lilly removing his bike from his vehicle.

The initial missing person report for Lilly was made to the Fayette County Sheriff’s Department on Monday, Oct. 22 when Lilly did not show up for work as scheduled at Oak Hill High School.

He was a teacher there.

Along with the Raleigh County Sheriff’s Department and the Fayette County Sheriff’s Department, the search for Lilly included a number of different police and fire agencies, the National Park Service, JanCare and citizen volunteers.
