Police charged a former Pittsburgh Public Schools police officer Wednesday with using his authority to sexually assault three troubled middle school students and provide a fourth with marijuana in crimes that date to 1998.
Investigators said they expect more accusers to contact them regarding Robert Lellock, 43, of Beltzhoover. The 22-year veteran was awaiting arraignment Wednesday night on 23 counts of offenses including child endangerment, official oppression, sex crimes and terroristic threats, because police say he told one boy he would kill him if the boy told anyone about the assaults.
