This document discusses a case study of "Joe", a homeless man with schizophrenia who exhibited paranoid and violent behaviors. Police officer Scott Mills and nurse Anne Marie Batten used Twitter to collaboratively manage Joe's case through the hashtag "#HomelessJoe". This allowed them to communicate about Joe's condition, locate him when he went missing, and engage community support for Joe. Through building trust with Mills and Batten using social media, Joe became more receptive to treatment and support. He secured housing and disability benefits, outcomes that likely would not have been possible without the social media intervention.
