TyChina Moore shares the sorrowful task of informing residents at Misericordia about the death of 26-year-old Brendan Siddall. Brendan worked closely with them as a direct service professional.

“Very devastated, still in shock. A lot of people who I reached out to, very emotional,” Moore said.

Early on Saturday morning, Chicago police attended to a collision at 3600 North DuSable Lake Shore Drive. In the northbound lanes, Siddall tragically lost his life after being hit by a vehicle. The driver fled the scene.

Chicago police are looking for a white-colored 2019 Honda Accord, a four-door, sedan with Illinois Plate FH49505.

The victim, Siddall, in addition to working overnights with the residents at Misericordia, was a member of the Chicago Gay Men’s Chorus.

In a statement released on Monday, the organization expressed their grief, “We grieve the loss of a cherished individual whose presence brought more love and inclusivity to CGMC. Brendan’s absence will be profoundly felt, but their essence will continue to inspire the music we create and the community we hold dear.”

At Misericordia, staff members are doing their best to comfort residents who are missing him.

“Brendan came in with a lot of enthusiasm, was really fun, worked well with the residents always had very high energy. Really great guy,” Moore said.

The staff is organizing a remembrance of Siddall to help them and the residents with their grief.
