A 25-year-old woman died after a two-vehicle crash early Saturday in northwest Indiana.

The crash happened about 1:30 a.m. at 109th and Maple Lane in St. John, according to St. John police and the Lake County coroner’s office.

Caitlyn Claire Amptmeyer was driving a 2008 Cadillac STS west when she rear-ended a 2016 GMC pickup truck, then struck a utility pole, St. John Police Chief James Kveton said.

Amptmeyer was extricated from the car and taken to Franciscan Health in Crown Point, where she was pronounced dead at 2:19 a.m., authorities said. She was a St. John resident.

“Based on the damage to the vehicle, speed was likely a contributing factor to the severity and fatality of the collision,” Kveton said.

Kveton said he did not believe the driver of the pickup was injured in the crash.

The Lake County sheriff’s office reconstruction team assisted with the investigation.
