PLYMOUTH — Strapped in a child restraint seat, 6-month-old Kristoffer Springman of Plymouth, died after the car he was riding in was hit by another vehicle.

The collision occurred before 2 p.m. Monday at U.S. 31 and 7B Road.

Jeremy Orbik, 35, of Plymouth, crossed U.S. 31 from westbound 7B Road when he was hit by a vehicle traveling south on U.S. 31, according to a Marshall County Sheriff’s Department report.

Orbik’s car slid off the road into a ditch.

According to a report from John Grolich, Marshall County deputy coroner, when Plymouth EMS arrived, Kristoffer was found in cardiac arrest and CPR was performed by bystanders.

Kristoffer was taken to St. Joseph Regional Medical Center in Plymouth, where he was pronounced dead at 2:26 p.m. after attempts to revive him were unsuccessful.
