WOBURN, Mass. (AP) – A man with a prosthetic leg was sentenced Friday to a year of home confinement for plowing into a crowd outside his grandson’s elementary school with his car last October, injuring 12 people.

“I’m as devastated as I’ve ever been in my entire life. I wish I could take it back,” said 66-year-old Enrico Caruso, who was convicted in April of negligent driving.

Caruso had just picked up his grandson at the school in Stoneham, outside Boston, when his car hopped the curb, pinning children and adults against a concrete wall.

Five people were seriously hurt, including a 5-year-old who lost a leg. Another child spent four months in intensive care, underwent more than 30 operations and nearly died from a rare viral infection.

According to a police report, Caruso’s grandson told investigators that his grandfather’s prosthetic right leg had gotten stuck on the accelerator. But at trial in April, the boy testified he could not remember how the crash happened.

Andrea Eustace, whose son lost his leg, said Caruso prolonged his victims’ suffering by not expressing remorse sooner. She said her son can’t walk and won’t be able to drive because he can’t bend his right ankle.

“It is heartbreaking to hear him say he doesn’t want to have only one leg,” she said.

Caruso received a two-year sentence, but the second year was suspended. His driver’s license was also revoked for five years and the judge said she would recommend it be permanently taken away.

Prosecutors had asked for an 18-month prison sentence.
