Police want to know who was supposed to be watching the Jamestown girl who was struck and killed by a car Friday evening when her sled slid into a busy road.

Authorities on Saturday identified the victim as 5-year-old Isabella M. Stanford, a kindergartner at M.J. Fletcher Elementary School in Jamestown.

“Our hearts go out to the family of this poor little girl,” said Capt. Robert Samuelson, of the Jamestown Police Department, “but we want everyone to understand this was a tragic accident that could have been avoided.”

The investigation is continuing. Police are still trying to determine whether there was any adult supervision at the time of the accident.

Late Friday afternoon, Isabella was sledding with three other children her age on a hill behind her home, which abuts Foote venue, Samuelson said.

The hill is probably 90 feet in length and has about a 20-degree incline, Samuelson said. It comes to an end at a sidewalk, which is just feet away from Foote, he added.

“It is a fairly short but steep hill – steep enough to get some speed,” Samuelson said Saturday. “There’s no reason anyone should have been sledding on that, given the slope and closeness to the road.”

Just before 6 p.m. Friday, Isabella came down the hill on her sled, slid into the road and was struck by a car traveling south on Foote, near Arterial Street.

“It’s a very busy thoroughfare,” Samuelson said, “especially that time of day on a Friday night.”

Isabella was taken to WCA Hospital, where she later died.

Samuelson said it was a difficult accident scene for all involved, including the first responders and the driver of the car that struck Isabella.

“The driver will not be charged based on what we discovered from the investigation,” Samuelson said.

It’s unclear how long the children were sledding on the hill, but by the looks of it, the hill had been used for some time, Samuelson said.

While Isabella was too young to know the danger, the adults responsible for her should have used more common sense, the police captain said.

“This was a tragedy that could have easily been prevented,” Samuelson said.
