An 8-year-old boy was injured Wednesday night when he was ejected from a snowmobile

involved in an accident with another snowmobile in the Town of Concord, Erie County sheriff's

officials reported.

Nicholas Mangano, of Lawtons, was taken to Women and Children's Hospital for treatment of

head and internal injuries. His condition was not available.

Nicholas' father, Mark Mangano, 42, was operating a snowmobile northbound on a trail south

of Route 39 at about 8:35 p.m., when his vehicle was involved in an incident with a southbound

snowmobile driven by Jay Vacco, 25, sheriff's officials said.

Investigators believe that the two operators both swerved to avoid a possible head-on

collision near a hillcrest.

"The investigation so far suggests that they got close enough that [Vacco's] shoulder made

impact with something, and it may have been the young man's helmet," said Sgt. Richard

Lauricella, who heads the sheriff's Snowmobile Unit.

The incident remains under investigation by the sheriff's Snowmobile and Accident

Investigation Units.
