PERU – A New Gloucester woman suffered a broken back Monday afternoon after the all-terrain vehicle she was riding crashed and rolled onto her, police said.

Lori Buchanan, 43, was in stable condition Tuesday evening in the intensive care unit at Central Maine Medical Center in Lewiston, a nursing supervisor said.

Maine Warden spokesman Mark Latti said Tuesday that Buchanan has a fractured spine, “but there is no paralysis.”

Buchanan was injured at 3:30 p.m. while riding a 1986 Honda 4-Trax four-wheeler on a snowmobile trail off 52 Main St., about 500 yards into the woods, said Latti and Oxford County Sgt. Timothy Holland.

“She was coming down over a hill when she lost control. The ATV rolled over several times and she landed under the four-wheeler,” Holland said late Tuesday afternoon.

Latti said Buchanan was driving down a steep grade that is very rocky.

“Midway down, there’s a left-hand turn, and she went to downshift to slow herself down – because she had no brakes – but she put it into neutral,” Latti said.

The ATV ran off the trail on the right-hand side, rolling over into woods and rocks. Buchanan wasn’t wearing a helmet.

Friends riding with the woman called 911.

“The machine was still on top of her when rescuers arrived,” Latti said.

In addition to Holland and investigating Warden Dave Chabot of Greene, Med-Care Ambulance responded, along with Peru firefighters.

Dixfield firefighters were also asked to bring their rescue sled, but it wasn’t used, Holland said, because the ambulance driver was able to get into the woods near the accident site.

There, rescuers secured Buchanan on a stretcher and carried her to the ambulance. She was then transported to a landing zone at Peru Elementary School and taken by LifeFlight helicopter to CMMC.

Holland blamed the ATV for causing the wreck.

“It looks like there was a mechanical failure,” he said.

Latti said Buchanan had borrowed the unregistered four-wheeler.

An investigation by Chabot is continuing, he added.
