A Tompkins County woman suffered a serious injury this morning when she rear-ended a manure spreader on Route 222 in the Town of Groton.
New York State Police say 41 year-old Jill Ashley Williams of Groton struck the farm equipment that was being pulled by a tractor shortly after 7 a.m.
A few minutes later, another vehicle operated by 71 year-old Albert Perreault of Groton crashed into both the pickup and the tractor.
Police say speed and a bright glare from the sun were factors in both accidents.
Ashley Williams had to be cut from her cab and flown by helicopter to a hospital in Syracuse.
