Jonas Cobb was a former Lieutenant in the United States Navy and also a serial killer operating under the name, "The Port-to-Port Killer".



NCIS Season 8Edit

The actions of The Port-to-Port Killer came to the attention of the team of the Major Case Response Team led by Leroy Jethro Gibbs when Derek Balfour was murdered. He lured him into an alley with a baby doll, playing a recording on repeat, at which point he slit his throat. He left the body in a field, wrapped in plastic and doused in cleanser, which the team was later called to investigate.

The arrival of The Port-to-Port Killer on domestic soil led to Director Vance forming a special task force to capture him, comprised of Gibbs's team and the team led by Agent Erica Jane Barrett.
