Allen’s mother Clara Allen called the act a senseless crime against her son.

“My plan is a non-violent group in our church, something that we can start voicing and calling people out for their actions,” Allen said.

Crime Stoppers hosted a press conference Monday at the Monroe Police Department announcing a $2,500 reward for information leading to Walden’s arrest. Police believe Walden could be in the Detroit area, where Walden may have family connections.
