WILKES-BARRE, Pa. (AP) — Police and school officials are imploring students to ask for help after four students have killed themselves in one northeastern Pennsylvania county in a single week.

Four teens ranging in age from 13 to 16 have killed themselves in a one week span in Luzerne County. A 15-year-old Pittston Area School District sophomore killed herself Monday night. Hours later a 13-year-old from Hazleton was found dead.

A second Pittston student, 16, killed himself on Friday and a Greater Nanticoke Area eighth-grader killed himself Sept. 18.

Authorities say the suicides don’t appear to be related to bullying despite hearsay claims to the contrary from students.

A Luzerne County District Attorney Stefanie Salavantis says students or anyone else having problems should call a suicide hotline or the Luzerne County Help Line.
