FARMINGTON – Lisa Cerqueira was remembered Wednesday as a great young person who always had a smile on her face.

She was, her fiancé said, “perfect.”

The 20-year-old Wilton woman died Tuesday night at a Portland hospital from injuries she sustained Friday night when a sport utility vehicle struck the snowmobile she was on.

She was a passenger on fiancé Rick Billian’s sled, which had crossed Routes 2 and 4 in Farmington from Boivin’s Harvest House Restaurant parking lot to the trail near Farmington Tire. The sled’s ski had become hooked on the road curbing, and the machine went sideways a bit. Billian got off to straighten the machine, and a vehicle driven by Sarah Forbes, 43, of Farmington struck the sled. Billian, an off-duty Farmington police officer, and Cerqueira were in a party of five snowmobiles that included two other off-duty Farmington police officers.

Billian recently told his grandmother, Marilyn Dussich of Jupiter, Fla., that Cerqueira “was perfect.”

The couple had known each other for about two years and had planned to marry on Aug. 18. “They had all their wedding plans in place; they were looking forward to their future, ” Dussich said.

“My grandson is devastated. We loved her. She was part of our family. We embraced her as she embraced us,” Dussich said. “I’m heartbroken.”

Cerqueira graduated from Mt. Blue High School in 2005.

“It’s very, very tragic. Very sad,” Assistant Principal Randy Cook said. “She was just a great kid. Always had a smile on her face. She was a hard worker.”

There were never any disciplinary issues with Cerqueira, he said.

“She was a real pleasant young lady to have in school,” Cook said.

In the 2005 yearbook, Cerqueira appears in several pictures with a smile on her face just as Cook said.

The information next to her picture is written in part in teenage slang with abbreviated words.

She wished friends good luck, thanked others and put initials of names down of people she had good times with.

She also wrote “Experience life, take risks, take chances, but don’t forget where ur going.”

Cerqueira, who suffered multiple injuries in the accident, including an injured aorta, a broken femur and several broken ribs, worked at the pharmacy at Wal-Mart in Farmington.

“We’re all deeply saddened by this young associate’s death, and our sympathy goes out to her family and to her friends,” said Marisa Bluestone, a representative of Wal-Mart media relations.

“She had many friends and colleagues who are now coping with the loss, and you know we’re certainly there for them to help them through this tragedy,” she said. “Our associates and store managers are planning to attend services for her, and I’m sure the store is going to do something special for the family.”

“Everybody’s taking the news pretty hard,” police Chief Richard Caton III said. “We’re concerned and clearly our thoughts go out to the family and, particularly, Rick.”
