Storylines
When the series began, Jennifer was new to Homicide and had previously been in the Fraud squad. She was meant to only be a temporary replacement for Duncan Freeman but eventually became a permanent member of the Homicide Squad.
In the season 1 episode "Lie Down With Dogs" Jennifer suffered a traumatic event when she had to shoot a teenage boy dead in self-defense. However in the next episode The Return, a meeting with the boy's mother, who eventually understood that Jennifer had no choice, helped her overcome this.
In the season 2 episode "Guilty As Charged", when a man on trial for murdering his wife and young daughter was found not guilty, Jennifer became determined to catch him at another crime. The man soon became as obsessed with Jennifer as she was with catching him and started stalking her and cornered her in the bush and tried to kill her. Matt and Duncan arrived in time to save her and the man received 5 years for attempted murder. Her colleagues all thought this sentence was too light, however, Jen stated that once his fellow inmates found out that he was suspected of killing his daughter, prison life would probably kill him, as men who harm children do not do well in prison.
In the season 4 episode "Reunion" it is revealed that Jen and Nick Buchanan worked undercover for the SIS as Trish and Wesley Claybourne in the past and that is how they first met each other. They were both forced to go back undercover by the SIS to help prevent a terrorist attack and in the episode "Undercover" Jen is shot in the shoulder by Travis Abbott but it was just a flesh wound so she survived.
