The St. Clair County Sheriff’s Office hosted an open house on Monday which served as the grand opening of a permanent history exhibit. The exhibit is lodged at the Sheriff’s Office, at 1170 Michigan Road in Port Huron. There are pictures and items on display from as far back as the turn of the 20th century. Also on display are items from the shootout with Herbert Youngblood in 1934 that ended with the death of Youngblood and Undersheriff Charles Cavanaugh. Sheriff William Van Antwerp was wounded in the exchange of gunfire. Youngblood and then Public Enemy number one John Dillinger had earlier escaped from an Indiana jail. The exhibit includes bullets from the exchange of gunfire as well as the shirt Cavanaugh wore during the shoot out and the notebook that saved his life. According to Sheriff Tim Donnellon, the history exhibit will be available to the public free of charge during normal business hours, Monday through Friday from 8:30 a.m. until 4:30 p.m.
