The condition of the 15-year-old North Yarmouth girl hit by a car in Gray Wednesday improved, hospital officials said this morning.

Delilah Talon was in critical condition when she was brought to Maine Medical Center Wednesday after a car drifted off the road, hitting her while she was walking with two friends.

Today, she was listed in serious condition, a hospital spokeswoman said.

The driver of the car, Earl Melendy, 83, of Gray, was not injured, nor were the girl’s two friends with whom she was walking.

The Cumberland County Sheriff’s Office is investigating the case.

A 15-year-old girl from North Yarmouth was critically injured Wednesday when she was hit by a car while walking along Route 26 in Gray.

Delilah Talon was hit and thrown into the windshield of a 1994 Ford sedan driven by Earl Melendy, 83, of Gray.

She was taken to Maine Medical Center in Portland with life-threatening injuries, said the Cumberland County Sheriff’s Office. A hospital spokesman said Wednesday night that Talon was in critical condition.

Melendy was driving north at 1:20 p.m. when he drifted off the side of the road and hit the girl, who was walking with two friends, authorities said. The two other girls were not hurt, and neither was Melendy.

Excessive speed doesn’t appear to have been a factor, said Chief Deputy Kevin Joyce. The speed limit in front of 189 Shaker Road, where Talon was hit, is 40 mph.

The three youths weren’t doing anything that contributed to the accident, Joyce said. They were walking in the correct direction, toward oncoming traffic, and were off the side of the road.

The sheriff’s office’s accident reconstruction team is investigating. The investigators are trying to determine whether Melendy had a medical condition that may have contributed to the crash, Joyce said.

Talon was walking away from Gray-New Gloucester High School; Joyce said he believes she attends the school. He did not know whether classes were held Wednesday.

At the end of the school year, students often have partial days because of exams.
