Authorities continue to investigate a three-car crash in Farmingdale Sunday morning that left four people injured and two cars impounded by police.

The crash happened when a southbound Jeep crossed the center line into the northbound lane, then swerved back, striking a southbound Chevrolet Malibu, and pushed that car into another southbound car, a Subaru station wagon, according to Major Ryan Reardon of the Kennebec County Sheriff’s Office.

The driver of the Jeep, Kerry Carter-Pushard, 46, of Gardiner, was apparently traveling at a high rate toward traffic that had slowed to allow the Subaru, driven by Richard Hayes, 80, of Hallowell, was turning into the Hi-Hat Pancake House on Maine Avenue, Reardon said.

Kelly Barton, 46, of Gardiner, who was driving the Malibu, was taken by LifeFlight to Central Maine Medical Center in Lewiston. A hospital spokeswoman on Monday said Barton remained there in serious condition.

Two passengers in the Malibu, Vicki Lachance, 45, and Brian Downing, 27, were both taken by Gardiner Ambulance to MaineGeneral Medical Center, Augusta. No residence was listed for the passengers.

Reardon said the investigating officer found that none of the people in the Malibu were wearing seatbelts.

A number of people saw the crash and spoke to the investigator, Deputy Galen Estes.

Reardon said it appears that Carter-Pushard’s speed and distracted driving were factors in the crash, and a blood sample was taken from her. She was also evaluated for injuries at MaineGeneral Medical Center. It was unclear whether charges would be filed.

Neither Hayes, nor his passenger, his wife Jean, 79, were injured.

The Jeep and the Malibu were impounded by police, Reardon said.
