An Allegheny County jury on Tuesday found 45-year-old Michael Johns, of Brookline, guilty of drug-related charges, insurance fraud, obstruction, making false statements to law enforcement, oppression and conspiracy.
Johns was found not guilty of promoting prostitution, theft, and other charges. He resigned from the department last year.
Johns was arrested last August after investigators said he paid for rental cars for the women, helped them obtain drugs and allowed them to use his home.
Sentencing is scheduled for Aug. 14. Johns is free on bond.
Defense attorney Marc Daffner said Johns is hoping to put the charges behind him and move out of state.
