"He called me last night at 11:00 and told me he knew where he wanted to go," Sandra Glass, Mitchell's travel team coach, told Scout.com.
This morning, Mitchell, a 6-foot-7 post prospect, made it official, verbally committing to Mark Turgeon and his staff at Maryland.
"He just put the phone call in five minutes ago," Glass said.
The visit played a major role in his decision, as did Maryland assistant coach Bino Ranson.
"To me what made him say Maryland, when he was up there he said he had a great rapport with the academic advisor," Glass said. "Coach Bino [Ranson], from all the schools he's been at from James Madison, to Xavier and to Maryland, was still recruiting him."
"He's built a great rapport with Charles, having recruited him throughout all of these years," she added.
"He loves the fan base," Glass said. "Charles went behind the scenes and looked at a lot of stuff. They told him they have 14 to 16,000 at games. He went and checked that out. I think the fan base played a big role as well."
Mitchell is Maryland's fifth commitment for the 2012 class. The three-star prospect joins four-star prospects Shaquille Cleare and Jake Layman, as well as local standouts Seth Allen and Damonte Dodd.
