An accident on Interstate 65 in Bowling Green has claimed the lives of six people.
The accident involved two passenger vehicles and two commercial vehicles, and happened around 10:30 p.m. Thursday night.

Two of the deceased have not yet been identified.
KSP troopers are helping lead the investigation into the cause of the accident.
A KSP news release says a preliminary investigation has revealed the accident happened at a particular portion of Interstate 65 where road construction was being conducted, and where the roadway merges from three lanes of travel into two lanes. Traffic was congested due to the construction.
A commercial vehicle was stopped in traffic, in the right lane of Interstate 65, with two passenger vehicles stopped immediately behind it. A second commercial vehicle approached in the right lane, failing to stop for traffic, striking the trailing passenger vehicle, causing a chain reaction collision.
