SALINE, MI — They called him their Peter Pan — someone always seeking fun, chasing the next trip, party or adventure, uneasy with the idea of “adulting.” But John Frick had begun to find his footing. He earned his degree from Michigan State University in December and landed a sales job in Chicago near his older sister, Emma. “I think Peter Pan kind of took off the hat and decided he was ready to not be a lost boy anymore,” his father, Chris Frick, said Tuesday, June 23, at his home in Saline.
