Two elderly siblings were injured and a third was charged with attempted murder after a high-speed chase Monday in Rockcastle County.

Clyde White, 78, of Corbin drove a white van that hit a blue van multiple times during the chase, which reached more than 100 mph, state police said. White's brother and sister were in the blue van.

An off-duty state trooper reported seeing a high-speed chase as the vans traveled south on Interstate 75 at 9:21 a.m.

The vans exited onto Ky. 461, and after White hit his siblings' vehicle multiple times, police said, he forced their van off the road, and it hit a DirecTV van that was parked on the shoulder near U.S. 150.

Lawrence White, 82, of Lexington, who was driving, and his sister, Dorothy Whitaker, 83, of Richmond, were flown to the University of Kentucky Chandler Hospital. White was released Monday, but Whitaker was listed in critical condition Monday afternoon.

The driver of the DirecTV van wasn't hurt. Clyde White fled after the crash, but his van collided with a tractor trailer.

White is charged with two counts of attempted murder and two counts of wanton endangerment. He was taken to the Rockcastle County Detention Center, where he was being held on $500,000 bond.

State police said they're still investigating.
