INDIANAPOLIS -- Indiana State Police need your help to find the driver of a truck who may be responsible for a chain reaction accident that killed one woman and critically hurt two others.
75-year-old Martha Southwick of Terre Haute was driving a van west on I-70 near the airport on December 19.
Troopers say a truck made contact with the rear of her van, causing her to overcorrect, cross the median and hit another car head-on.
Authorities say the truck driver didn't stop.
"Not only is it the law but it's the humane thing to do. These people were critically injured in this crash whether it's the fault of the driver of the commercial motor vehicle or not. By law, you need to stop and render first aid if it's a personal injury accident," said Sgt. Rich Myers, Indiana State Police.
Troopers also don't know if Southwick's van first made contact with a semi or box truck, or whether the truck driver is to blame.
None of the witnesses who came forward saw the truck and no INDOT cameras captured the accident.
State police say if you saw that truck prior to or after the accident, contact the Indianapolis state police post.
