Authorities said it happened around 3:30 p.m. along Cincinnati Pike, about three miles north of Sadieville.
Investigators said five cyclists, riding cross country raising money and awareness for young adult cancer victims, had stopped off on the side of the road to do some bike maintenance, when a pickup hit two of the cyclists.
Investigators said one of the cyclists wasn’t seriously injured, but the other, identified as Jamie Peters, 24, of Baltimore, Maryland, was killed. She was pronounced dead at the scene.
Investigators said the road was popular among cyclists because of its beauty, but that it could also be dangerous.
"This is a very rural road, not much in the way of shoulders, a lot of curves and hills which again, makes it dangerous for both people, bicyclists and the vehicles involved. It is a very troubling situation," said Scott County Sheriff’s Deputy Jearl Porter.
Investigators said the driver of the pickup truck was devastated by what had happened.
Authorities said he was fully cooperative with the investigation.
The driver was taken in for questioning and submitted to medical tests to determine if drugs or alcohol played any part in the accident.
The results were not immediately known.
A collision reconstruction specialist from the Georgetown Police Department was brought in to reconstruct the accident to try to determine exactly what happened and how.
Investigators said Friday night that it was too early to determine if the pickup driver would be charged criminally or cited in the case.
The investigation was ongoing.
The cyclists were riding the 4K for Cancer, which is a program of the Ulman Cancer Fund for Young Adults.
It is a non-profit organization that is dedicated to enhancing lives by supporting, educating and connecting young adults, and their loved ones, affected by cancer.
In 2013, 127 4K for Cancer participants traveled across America and raised nearly $775,000 to support young adults with cancer, according to the organization.
