Driving while sleepy is almost as dangerous as driving drunk. Cass County Sheriff Richard Behnke tells WSJM News his office was called to a personal injury crash on Barron Lake Road in Howard Township just after 12:30 Sunday morning. Behnke reports 29-year-old Tiffany Hisler of Dowagiac stated she was southbound on Barron Lake Road when she fell asleep. She ran off the roadway striking multiple mailboxes and a utility pole. She was transported by ambulance to Memorial Hospital in South Bend for further treatment of her injuries. He says she was wearing her safety belt and alcohol is not believed to be a factor and the crash remains under investigation.
