(KNZA)--A multi-vehicle chain-reaction wreck in St. Joseph, Missouri Thursday morning claimed two lives and left another person seriously injured.

KQ-2 TV reports the wreck happened shortly after 9:00 on the northbound I-229 offramp to U.S. 36 Highway.

The St. Joseph Police Department said a fully loaded semi-truck struck the rear of a pickup truck. The crash forced the pickup into the back of a fully load dump truck, causing it to rear-end a commercial boom truck.

Two passengers in the pickup were killed. Police identified the victims as Diana Ptomey and Joyce Ptomey. Joyce Ptomey is a former lifelong Troy, Kansas resident.

The driver of the pickup had to be extricated. He was transported to Mosaic Life Care, in St. Joseph, with suspected serious injuries.
