Patrick Kelly Behan, 29, was killed on November 13, 1990, in Pembroke Park, Florida, while on duty. He was sitting in his patrol car at a Circle K on Hallandale Beach Boulevard and SW 40th Avenue, writing a report after responding to a shoplifting call, when he was ambushed and shot at point-blank range.

Behan had only been a patrol deputy for two weeks, although he previously served with the Broward County Sheriff's Office and the Boca Raton Police Department. One suspect was arrested and convicted in connection with the killing, but that conviction was overturned in 2003 when a judge found the evidence insufficient to sustain it. The case remains unresolved and has drawn scrutiny over investigative and prosecutorial steps taken.

Anyone who knew Deputy Behan, was in the area that night, or has information that could help bring closure to his family is asked to come forward.
