It all started on the weekend when he was accused of firing a handgun in Miminegash. Police caught up with him days later after he allegedly killed a dog. CBC’s Nicola MacLeod explains.Lannigan left that scene as well, and wasn’t spotted again until his vehicle was seen heading into Summerside at high speeds. Summerside’s police chief said officers did not pursue at the time out of public safety concerns, but police later issued an emergency alert asking residents to shelter in place.The alert characterized Lannigan as an “armed and dangerous individual” as he was believed to be moving through the city on foot. He was later arrested by two RCMP officers on a kayak. Witnesses told CBC News that Lannigan first entered the water on a kayak he took from a residence and was then pursued by officers who borrowed kayaks from the same homeowner. 17 firearms chargesLannigan now faces 20 charges for the events over those two days. None of the allegations have been proven in court.17 of the charges are firearms offences, including careless use, improper storage and tampering with a serial number.Police officers combed Summerside with their weapons drawn as they searched for Lannigan on July 23. (Nicola MacLeod/CBC)Police said they seized a handgun on the day Lannigan was arrested in Summerside.Handguns sales, transfers and purchases have been halted since 2022 due to a “national freeze” that was later wrapped into Bill C-21 when it passed in 2023.Three of the charges also allege that Lannigan was banned from owning firearms due to a previous court order. He also faces three non-firearms charges: an assault for the alleged fight in Miminegash, breaching a previous probation order and endangering animals connected to the alleged shooting of the dog.
