HAMPSTEAD - An East Hampstead man, injured in a collision Monday night on Central Street, has died in a Boston hospital, according to police.

Kevin Coady, 20, was riding a non-motorized scooter just after 5:30 p.m. on Central Street, near Moulton Drive, when he was hit from behind by a van operated by Christina Soucy, 34, of Plaistow.

Police said it was dark outside and Soucy did not see Coady, who was dressed in black. Coady suffered a serious head injury and was flown to Beth Israel Deaconess Medical Center in Boston where he died Wednesday.

Investigators said there is no evidence suggesting speed or impairment contributed to the crash. No charges are expected against Soucy.
