Investigators are trying to figure out why an ambulance driver in the Chicago suburb of Bellwood smashed the vehicle into a building with such force that it killed him, a co-worker and a patient.
Bellwood Mayor Andre Harvey says there is no indication the driver applied the brakes before the collision at about 3:48 p.m. Saturday.
According to Harvey, both the Bellwood Fire Department and the Bellwood Police Department received calls about a vehicle that hit a building at the 2800 block of Washington Blvd. The fire department was alerted due to a fire alarm that went off when the collision occured.
Harvey also said the ambulance was not involved in an emergency but was simply transporting the patient from a hospital to his residence when the crash occurred.
The Bellwood Mayor also said an autopsy would be conducted to determine if the driver was suffering a medical emergency at the time of the collision.
The driver and the male patient were pronounced dead Saturday and a third man, an ambulance attendant, died at an area hospital early Sunday.
It is unclear what happened and the investigation was on going.
