Authorities are investigating the apparent drowning death of an Indiana teenager in Cass County. The sheriff’s department was called to Long Lake in Porter Township at 7:30 Tuesday night when 19-year-old Janelle Miller of Shipshewana took a break from wake boarding with friends and left their boat for a swim. The group called 911 when they couldn’t find her in the water, and then dove in to search. Deputies also were unable to locate her, and neither was West Michigan Air Care as the helicopter scanned the lake. It wasn’t until just before 11 p.m. when the Van Buren County Dive Team and Cass County Marine Division were able to find Miller’s body. She was not wearing a life jacket, but police say alcohol was not a factor in her death.
