Law enforcement officials and rescue crew members stand around the crash scene where a bicyclist was killed Thursday. Earlier in the day a skateboarder was struck and injured in a separate incident.

A woman who was visiting Virginia Tech for a religious conference was killed while riding a bicycle on campus Thursday.

In a separate incident earlier in the day, a man who was attending the same conference was critically injured while skateboarding, also on campus.

Tech spokesman Larry Hincker said the woman was struck by a dump truck about 4:30 p.m. near the intersection of West Campus and Drillfield drives.

Bonnie Tinker, 61, of Portland, Ore., died at the scene, Hincker said.

Hincker said Tinker was on campus with the Religious Society of Friends, who are using university facilities for the Friends General Conference this week. About 1,300 people are attending that event.

The dump truck, owned by William G. Simmons Co. of Narrows, was contracted by the university, Hincker said. It was hauling fill dirt from an area near Lane Stadium to a site close to Schultz Dining Hall. Police closed the streets at the intersection where the accident occurred. The identity of the truck driver has not been released.

Virginia Tech police are investigating the incident, and a regional crash team also at the scene included investigators from Montgomery County, Christiansburg and Blacksburg. State police officials are investigating as well because of the involvement of a commercial vehicle in a fatal accident.

Conference coordinator Traci Hjelt Sullivan said Tinker, an activist who focused on gay and lesbian family issues, was the executive director of an organization called Love Makes a Family.

Earlier in the day, about 9:20 a.m., a man was critically hurt on campus while skateboarding between Dietrick and Payne halls, according to Tech police Capt. Joey Albert. Albert said the injured man is not a student and was flown to Carilion Roanoke Memorial Hospital.

Bruce Birchard, general secretary for the conference, said the man was listed in critical condition Thursday night. He declined to release the man's name but said the man is from Pennsylvania.

The Friends General Conference includes workshops on spirituality and activism, and is due to end Saturday. Sullivan said events Thursday evening were cancelled.

In December, a freshman died on campus after he fell from a skateboard near Aggie Quad Lane.

In early 2008, a car struck a group of five pedestrians on campus. One student was killed and three others injured.
