"He showed up at his school (Durfee Elementary) this morning," she said. "He had gone to a friend's house and it got late, so he spent the night there. They didn't have a phone to call," Termina Washington told the Detroit News.
Tywon was last seen with a female neighbor around 7:30 p.m. Wednesday, an earlier report indicated. Washington said she went to the neighbor's house but her car was gone and no one answered the door.
Washington had said it was unlike her son not to call if he was going to be late, the Detroit Free Press said.
"It's not like my son -- he would have called me," Washington said Thursday before she learned her son had showed up for school. "If he's 15 minutes late coming home from his friend's house, he calls me. I've been up all night. I've been out on the street all night. And now I'm going out because it's time for kids to go to school."
