PIKE COUNTY, Ind. (WDRB) -- Indiana State Police say three people were killed in a crash that happened Friday night in Pike County, and drugs may have been a factor.

A news release from Indiana State Police says a trooper witnessed a head-on collision involving three vehicles on I-69 near the 49-mile marker. Officials say the crash happened around 9:45 p.m.

A trooper was parked on the southbound side of I-69 at the 42 mile marker around 9:30 p.m. when a driver stopped and said the driver of a Chevrolet Tahoe was going north in the southbound lanes.

Officials say the trooper then headed north and located the Tahoe traveling north in the southbound lanes around the 48.5 mile marker.

The trooper drove into the median and tried to get the wrong way driver's attention. Authorities say the driver then entered the median and made a U-turn and proceeded south in the northbound lanes.

The trooper then entered the southbound lanes still trying to get the driver's attention. Police say the Tahoe hit two other vehicles minutes later near the 49 mile marker.

The other two vehicles involved in the accident were a 2011 GMC Terrain and a 2014 Ford Focus.

State Police say the driver of the Focus was 22-year-old Stephanie Molinet. She was taken to the hospital, where she later died from her injuries. Authorities say a passenger in the Ford Focus, 21-year-old Autumn Kapperman, was also killed in the crash. Investigators also say Kapperman was five months pregnant.

Jason Lowe, 44, also died at the scene. Samantha Lowe, 46, is being treated for her injuries at Deaconess Hospital.

Police say the driver of the Tahoe was taken to the hospital to be treated for non-life threatening injuries.

The northbound lanes of I-69 were closed for about three hours as officers worked the scene.

Authorities are continuing to investigate the crash.
