Serious mustache

Exploration Stage: Rapture Theater
From: Valerie
Description: One of the missing from the theater is Gregory Collins. His famous feature was his impressive mustache. He always meticulously groomed it. This gentleman carried a comb for his mustache. Check out the actors on stage. The one with the mustache comb is the missing Gregory Collins.
Completed: I found a mustache comb in the pocket of attorney Tulane's jacket. I'm guessing he's the missing Gregory Collins in this role. Anyway, he's not J.L.
