The family of a man who was found dead in a bathroom at PPG Paints Arena wants to know why his body went undiscovered for more than 40 hours. During the Oct. 5th game at the arena featuring the Penguins and the Blue Jackets, Tim Helbig — a sound technician working for AT&T Sportsnet — complained of severe pain and told co-workers he needed to leave. It would be the last time anyone would see or speak with him. Two days later — in a check before Oct. 7’s Black Keys concert — Helbig’s body was found inside a locked family bathroom on the arena’s third-floor concourse. He had been in that bathroom — undiscovered — for more than 40 hours. Detectives say there was no sign of foul play.  It is not known when Helbig died, and medical experts say it is very difficult to determine a time of death in these cases.
