Authorities say good Samaritans saved the lives of two seriously injured occupants after rescuing them from a truck that crashed into a building and caught on fire in Beach Park.

The Lake County Sheriff’s Office, Waukegan Fire Department and Beach Park Fire Department responded around 3 a.m. Sunday to the CubeSmart Self Storage, 37021 North Sheridan Road in Beach Park, for a vehicle crash.

Sheriff’s deputies arrived and located a Chevrolet Silverado engulfed in flames, according to Lake County Sheriff’s Office Deputy Chief Christopher Covelli.

Deputies learned that good Samaritans had pulled the driver and a passenger of the Chevrolet from the vehicle.

Covelli said the actions of the bystanders likely saved their lives.

A preliminary investigation showed the Chevrolet, driven by Roy R. Montoya-Medina, 23, of Waukegan, was traveling eastbound on Blanchard Road at a high rate of speed.

The Chevrolet left the roadway for an unknown reason, drove through a grassy area and struck the south side of a self-storage building.

The pickup truck ignited in flames after striking the building, Covelli said.

Montoya-Medina and his passenger, a 25-year-old Antioch man, were seriously injured in the crash.

They were transported to an area hospital for treatment of their injuries, which included serious burns.

Covelli said building inspectors were called to the scene to evaluate the building’s structural integrity.

Deputies determined that Montoya-Medina was driving under the influence of alcohol.

He was charged with driving under the influence and reckless driving. Montoya-Medina is scheduled to appear in court on January 24.
