MORRIS – State Trooper Jill E. Mattice, 31, was killed in a head-on collision with a tractor trailer at about 2:50 p.m. Wednesday on state Route 23 in the Town of Morris.

State Police investigators said Mattice was traveling east on Rt. 23 when she was involved in a collision with a westbound tractor trailer being operated by F.M. Saggese, 33, of West Oneonta.

Police have not released any further information about the accident and have referred all questions regarding the incident to a press conference scheduled for 1:30 p.m. at Troop C Headquarters in Sidney.

Mattice was a six and a half year veteran of the State Police and served as the School Resource Officer for the Unadilla Valley Central Schools in New Berlin and the Franklin School Districts in Otsego County since 2006.

Just hours before her fatal crash, she was meeting with elementary students at Unadilla Valley, in one of the many roles she performed at the district, said High School Principal Frank Johnson, who shared an office with Mattice. Her duties at the school brought her to the district a “few times” a week where she aided teachers in the legalities of dealing with certain school issues and provided support to students seeking aid, even teaching lessons in the classroom, he said.
