A performing arts center in suburban Detroit reopened over the weekend with performances of “The Nutcracker," days after a body was found in the building's ventilation system. The body was discovered on Nov. 26 while authorities were investigating a foul odor at Macomb Center for the Performing Arts in Clinton Township. Investigators believe 36-year-old Jason Thompson suffocated after squeezing himself into the vent system through an opening on the roof. Foul play is not suspected.
