john headed to work in time for a weekly office barbecue at the company he co-owned with partner dave stuben>> him and dave sometimes had some differences on things, but, you know, that's certainly not unusual in a business. >> around 7 p.m, john calls a friend, making plans to meet for dinner. he never showed up, and later that evening, john's girlfriend renata tries calling him. he never picks up. >> so renata, his girlfriend, is like frantic calling. calling. she called the police and they said nothing we can do until matters turn alarming. >> the next night, when john is a no show for a gig, we kept thinking he was going to walk in and plug in and everything would be fine, but then he didn't. >> whenever an adult has what we would consider a fairly successful life as a girlfriend has family, has no obvious reason to disappear on his own. >> certainly we think right away foul play could be involved here. >> saint charles police and dupage county sheriff's detectives are notified they bring cadaver dogs to where john was last seen alive. universal cable construction partner dave stuben all
