A deadly crash closed all southbound lanes of I-75 in Rockcastle County Tuesday evening.

The crash happened near the 72-mile marker, between Berea and Mt. Vernon.

Kentucky State Police say 69-year-old Jack McIntosh of Richmond was driving a wrecker towing a disabled semi.

McIntosh merged onto I-75 when 70-year-old Samuel G. Thomas of Candor, NC struck the rear of the semi being towed.

The Rockcastle County Coroners pronounced Thomas dead at the scene.

No one else was injured.
