Sullivan County is mourning the loss of three North Central High School sophomores who were killed in a single-vehicle crash Friday afternoon. More than 500 people filed into the North Central High School Gymnasium Sunday afternoon for a vigil to remember 16 year-old Thomas K. Jaroscak, 16 year-old Kegan Ennen, 16; and 15 year-old Tyson Boyll. The three boys died Friday from injuries suffered in an accident when a car driven by Jaroscak was traveling east on County Road 1100. Jaroscak lost control, ran off the road and struck a tree. The crash remains under investigation by the Sullivan County Sheriff’s office and Indiana State Police.
