Pittsburgh police said this morning that they traced an online threat targeting a city hospital to a Beaver County teenager. Police said investigators “successfully traced the threat,” which was made on Twitter, to a Beaver County location. Police said in a statement this morning that they interviewed a male juvenile and his family early this morning and determined that the juvenile teen had no intentions to carry out the threat.  Law enforcement officials received numerous tips since releasing information on the threat last night. The tweet, posted around 12:40 p.m. Tuesday, mentioned that a “hate crime” would be committed this morning at an “undisclosed” hospital. Police said detectives had been “working all angles” through the night trying to determine the origin of the tweet. The investigation involved law enforcement from “multiple jurisdictions.” Police said they continue to investigate.
