According to his mother, Liz Atchison, Mike has been returned home "safe and sound."
"He was found," said Atchison on Sunday afternoon. "Someone recognized him from the Facebook post from the Patch news article."
Mike's mom said that a Patch reader "held him at their home" until she picked him up around 1:30 p.m. on Sunday afternoon.
"He is home safe," she was happy to report.
Atchison thanked Patch for its work in finding her son.
"The article was a key part of reaching the right people, in order to have people see his face," she said. "They recognized him because of [Patch's] post."
Mike's mother said he was safe and sound, with no injuries reported.
"He is fine," she said.
