Search underway for 19-year-old missing since Nov. 29

7 weeks ago, 19-year-old Trey Rogers was dropped off at Wayne County Community College in Detroit. Later that day, his phone was recovered on the Belle Isle Bridge. Trey hasn't been seen since and now his family is desperate for answers. "I need to hear his voice. I need to know he's alright," Trey's sister Courtney Wimbush said. ​But for 7 heart-wrenching weeks, it's been silent. ​Her 19-year-old baby brother has been missing since November 29. ​ "I can't sleep, when I think of him I can't eat because I don't know if he's hungry or sleeping somewhere warm," Trey's grandmother ​Margaret Rogers said.
