One motorcyclist was killed in a wreck, and three others were arrested Friday night after all four refused to pull over for a traffic stop in West Ashley, Charleston County sheriff’s deputies said.

While trying to evade a traffic stop, three of them wrecked in two separate incidents, and one died. Another was treated for injuries.

S.C. Highway Patrol is investigating the wrecks, which happened about 8:30 p.m. on Wappoo Road, according to an incident report filed by the sheriff’s office.

The report states that a sheriff’s deputy spotted seven motorcycles speeding west on Wappoo Road at Savannah Highway and tried to pull the group over.

Three of the motorcyclists pulled into a nearby BP gas station and were issued warnings for speeding. The other four, however, sped toward Edgewater Drive and refused to stop for blue lights, deputies said.

In the first collision, deputies caught up with two of the four motorcyclists when they wrecked on a wooded stretch of Wappoo Road. Both of those riders were wearing helmets, said Lance Cpl. Judd Jones of the S.C. Highway Patrol.

The driver of a 2013 Yamaha, was taken to Medical University Hospital where he died from injuries sustained in the wreck, Jones said.

The Charleston County Coroner’s Office identified the dead man as Beaumont Williams, 20, of Ohio.

The driver of the second motorcycle, 19-year-old Alexander Mock of Goose Creek, lost control of his 2006 Suzuki and fell off, Jones said. He was not injured.

Another motorcyclist identified as 20-year-old Matthew Kapp of Goose Creek walked up to the wreckage saying he was a volunteer firefighter and asked deputies if he could help.

Deputies determined that Kapp was one of the motorcyclists who had refused to pull over, according to the report. Kapp reported that he didn’t stop because he didn’t see the deputy’s blue lights.

Authorities found the last of the seven motorcyclists, 19-year-old Tanner Yearick of Goose Creek, after he wrecked in a ditch, the report states.

Yearick was treated at Roper Northwoods for injuries sustained in the wreck.

Deputies charged Mock, Kapp and Yearick with failure to stop for blue lights. All three motorcyclists were held at the Charleston County jail on the charge.
