Three suspicious house fires are under investigation in Algonac. The St. Clair County Sheriff’s Office Fire Investigation Unit is looking at three fires that are deemed suspicious in nature, according to a statement released on March 18. The first fire occurred on March 2 in the 2500 block of St. Clair River Drive. The second fire was in the 100 block of Algona. The third fire was on March 15th in the 1200 block of St. Clair Boulevard.
