Police investigators found that Grossheim had keys to all four men’s rooms, and was the last person to see or talk to all five people before their deaths.

Grossheim was the “House Manager” at Alpha Kappa Lambda, and was the building manager at the apartment complex where the unnamed man died, the suit says. Grossheim allegedly was the first person to find Mullins and Hughes dead in both cases, the suit says. Thomas was allegedly found dead near a scrap of paper with Grossheim’s name and contact information on it.

Two fraternity brothers in supervisory roles told police that they had problems with Grossheim and that he had been acting “strangely,” according to the suit. Grossheim allegedly told people he considered himself a “superhero” with the nickname “peacemaker.”

“He counseled and gave advice and ‘step-by-step directions’ to people on how to deal with depression and do their own ‘free will,’” Gorovsky said. “The victims then each committed suicide in a very specific and tragic way.”

Mullins and Thomas told fraternity members that they had stopped taking their prescribed medications, the suit says; Truman State counseling services emailed Mullins about missed appointments but otherwise didn’t follow up.
