Emma met Joseph at St. Therese Academy where he was working as a custodian. They married in 2005. In April 2012, Emma was working at a convenience store as robbers entered. They demanded money, which she gave them. As she reached for the phone, one of the robbers shot her in the stomach, killing her.
Emma's death is what caused her husband, Joseph Falk, to have a psychotic breakdown, he would later become a vigilante, terrorizing the Glades, acting as judge, jury and executioner; killing innocent people in cold blood, this was what eventually led to Joseph's painful yet deserved/justified death at the hands of Oliver Queen (under the persona of the Hood).
