BELGRADE — A 3-year-old Belgrade boy remains in critical condition at a Portland hospital today after the stroller he was riding in was hit by a truck on Route 135.

The boy, who was not identified by police, was taken by a LifeFlight helicopter to Maine Medical Center, where he was listed in critical but stable condition with head trauma, said Kennebec County Sheriff Randall Liberty.

The truck also hit a 13-year-old Belgrade girl who was babysitting the boy and pushing the stroller. The girl, whose name was not released, was treated at Maine Medical Center and released.

“The baby sitter is home but may need reconstructive facial surgeries,” Liberty said.

The 3-year-old’s brothers, ages 4 and 9, were walking along the road at the same time but were not hit by the truck, according to Liberty. 

Neither speed nor alcohol appear to have been factors in the crash, Liberty said.

The crash happened about 5 p.m. Friday near 130 Manchester Road. The children were walking west against traffic in the east-bound lane.

Elton Bowler, 48, of Augusta, was driving his 2001 Dodge Ram 2500 pickup truck east when he came upon the children.

“The pickup truck struck the baby sitter and the 3-year-old boy, throwing them approximately 5 feet into the ditch,” Liberty said.
