"The ambulance driver was at fault for the crash," State Police spokeswoman Trooper Melissa Matey said Tuesday. "We'll turn it over to the district attorney's office to determine if charges will be filed."

The investigation is ongoing, but the ambulance's speed is considered a factor in the accident, authorities said.

Baio was responding to a call for service and had the ambulance's emergency lights and siren activated, according to authorities.

The accident happened on Airline Drive in Destrehan shortly before 5 p.m. near the intersection of St. Rose Avenue. Authorities say the ambulance was traveling south on U.S. 61 when for unknown reasons the vehicle "drifted" into the left turn lane and hit the rear bumper of a 2012 Cadillac CTS.

The Cadillac was pushed into the northbound lanes of Airline Drive where it was struck by Jackson's 2008 Toyota Rav4. Jackson's vehicle left the roadway and caught fire, according to a State Police release.

Also treated in the emergency department at the Salina hospital were the driver of the ambulance, Kyli McGreevy, 23, of Ellsworth; and medic Alesha Schoshke, 33, of Lindsborg.

Phelps' northbound red 2002 Pontiac Firebird was attempting a west turn onto Crawford Street on a green light when the collision with the ambulance headed east on Crawford occurred. The front of the ambulance struck the driver's side of the car.

Witnesses at the scene of the crash said the driver of the car flew out of his rear window and was lying under the front of his car after the vehicle spun during the crash.

"He was pinned under the front tires, myself and the other first individuals on scene lifted the vehicle up and rolled it back off of him," wrote Tyler Grimes in an email to the Journal.

"I found the truck, browsing the internet one evening. I sent the link to our senior officers Chief Robert Hunt, Asst. Chief Andy Fouch, Asst. Chief Kenny Smith and Lieutenant Freddy Justice," said young volunteer firefighter Jordon Mounts. "They all agreed that this was the truck we had been searching for. I placed a call into the company that was selling the truck who told me the truck was originally purchased by a paid department in New Jersey, who used it as their first out truck on fires."

"We noticed a couple of years back that our call volume versus fire and rescue was something like 80 percent to 20 percent," Chief Hunt said. "With our older truck having more than 100,000 miles on it, we were not sure how much longer it was going to be reliable."

"After a meeting where Chief Hunt presented the truck to the Board of Directors, a call was made to Glenn Usdin of Command Fire Apparatus in Lancaster, Pennsylvania," Mounts continued. The President of the Board, Bob Preece, struck a deal with Command FA for $105,000, which included lettering and delivery.

The new unit is equipped with generator hose rollers on both sides of the truck and also a back-up camera and water tank that increases capacity from the current unit's 250 gallons to 500.
