MEXICO — A Peru woman could not remember hitting the accelerator on her Mazda pickup truck Wednesday afternoon in the Walmart parking lot, which led to more than $21,000 in damage to seven vehicle, police said.

“I couldn't believe it when I got there,” Mexico Lt. Roy Hodsdon said.

What he saw were damaged cars, trucks and SUVs, and Louise Gerrish, 88, of Pleasant Street in Peru sitting in her 2000 Mazda pickup.

Hodsdon gave an account of the crashes. He said Gerrish apparently hit the accelerator on the truck, sending it across the medium and into the left side of a 2006 Chrysler Pacifica owned by Jessica Robinson, 29, of Kidder Avenue in Dixfield.

Gerrish's pickup continued on, nearly hitting a pedestrian who had been standing at the rear of Robinson's Chrysler. The truck continued across another row of vehicles and struck the right side of a 2006 Ford sport utility vehicle owned by Jane Lueders, 49, of Canton.

At the same time Gerrish's pickup hit Lueders' vehicle, it hit the left rear side of a 2010 Subaru Forester owned by Maggie Henien, 42, of Moore Street in Bridgton. The Forester was pushed into a 2004 GMC pickup truck owned by Timothy Derouche, 55, of Roxbury.

Hodsdon said the Mazda pickup continued traveling north in the parking lot, crossed another row, and struck a 1994 Ford pickup owned by Kevin Quinn, 73, of Rumford. The Ford pickup was pushed forward across two empty parking spaces into a 2007 Subaru sedan owned by Jean Mayo, 59, of Pine Street in Rumford.

Gerrish's pickup stopped after that.

Hodsdon said Gerrish said she doesn't know what happened and doesn't remember the crashes. She refused medical treatment for bruises.

He attributed the crashed to driver error.
