"People Are a Resource" episode 3 deaths
Luther (Michael Anthony), a member of the Tribespeople, was never very fond or trusting of Negan. He knew something was up, and this is confirmed when he finds the wanted poster with a familiar face; he questions Negan, which leads to a brawl and Luther's death. It was an amazing action sequence where Negan uses a cheese grater and exposed pipe to kill his opponent.
"Everybody Wins a Prize" episode 4 deaths
Rizza (Alixa Kendrick), known as the scavenger lady, is first seen on the streets as she discovers Ginny's missing dinosaur stuffy. During the battle royal in the arena, she is killed by walkers. Several other Tribespeople also died in this battle.
"Stories We Tell Ourselves" episode 5 deaths
The series seemed to set up the Tribespeople as a group who would come alongside Maggie and Negan in future seasons. But the deaths of Tommaso and Amaia (Karina Ortiz) in episode 4 have made it obvious this won't be the case. Tommaso and Amaia fought walkers in the sewers with Maggie and Ginny but sadly didn't make it out alive.
"Domo Smo" episode 6 deaths
It was surprising that the season 1 finale of The Walking Dead: Dead City didn't include any deaths. The last episode was focused on setting up the stories that will carry into the next season.
