The Jefferson County Sheriff's Department has corrected the names of three sisters involved in a wreck Friday on Michigan Road that left two young girls critically injured.

Micha Willoughby, 3, and Ruby Willoughby, 5, were riding in a sedan when it collided with a truck on Michigan Road at Virginia Avenue.

Both girls were flown to Kosair Children's Hospital in Louisville and were listed in critical condition Friday night. A condition update was unavailable today.

The vehicle, driven by the girls' sister, Jennifer Huff, was southbound on Michigan Road and collided with the pickup truck while attempting to turn east onto Virginia Avenue.

The truck struck the back passenger's side of the sedan, knocking both vehicles off the road.

The Willoughby sisters were wearing seat belts but neither was in a car seat, according to the Jefferson County Sheriff John Wallace, adding that Ruby Willoughby was sitting closest to the impact.

Wallace said blood tests revealed alcohol was not a factor in the accident.

The accident occurred at about 6 p.m. when a heavy rain system was moving across the county. Wallace said the Indiana State Police Accident Reconstruction Team was at the accident scene Friday evening and will investigate all possible factors such as speed, visibility and weather.
