Three people were arrested Wednesday night in a drive-by shooting in the 400 block of Duquesne Avenue in Canonsburg. Canonsburg Mayor Dave Rhome tells WJPA News that it happened around six o’clock. There were no injuries and Rhome says police were able to make the arrests very quickly. All three are being held in the Washington County Jail. Rhome says the investigation is ongoing but he says the incident was an isolated one and there is no threat to the public. Rhome says he went door to door in that neighborhood last night to reassure residents that they were safe.
