Colin Donnell is a One Chicago legend. The actor played Dr. Connor Rhodes for four seasons on Chicago Med, and participated in some of the show’s most indelible storylines. It’s been a long time since fans have gotten to see him walk through the halls of Gaffney Medical Center, but Donnell is very much still part of the franchise family.

This connectivity was evident on Tuesday, April 8. Donnell took to Instagram to pay his respects to Michael Waxman, a former executive producer and director on Chicago Med. Waxman’s information is hard to come by online, but Donnell claimed that the television veteran passed away. He also made a point to emphasize how much Waxman played a role in shaping the show we still watch today.
