PITTSBURGH – A suburban Pittsburgh teenager is accused of trying to kill his sleeping family by placing homemade chlorine bombs in their beds.

Police say 16-year-old Christopher Janney, of South Fayette, built “compression bombs” that he placed near five family members late Friday or early Saturday.

A police affidavit says his mother called police Saturday and showed officers six bottles containing chlorine.

The boy was found and arrested Sunday. He is charged with five counts of attempted homicide and other offenses.

Police seized a gas mask, a pepper grinder and ground rat poison from the home and say two other people may have assisted the boy. They have not been charged.

Janney has a preliminary hearing scheduled for Wednesday.
