She died in hospital on Tuesday, the same day police announced the arrests of the two men, saying Parisian was wanted on a Canada-wide warrant for unrelated offences when he was picked up in Vancouver. Police say he suffered a serious bite wound from a police service dog during the arrest and was treated and released from hospital. The Independent Investigations Office, which examines police-involved injuries, was notified. Bouthilette was taken into custody a few hours later near the city s Downtown Eastside.
