In Sheriff: Narko Integriti, Jennifer Wong is revealed to be one of Tony’s moles in the police force. Elizabeth Tan plays Jennifer.
When the narcotics department fails to catch the Meth Killer, ASP Jennifer Wong, also known as Jane, is assigned to the case. She is tasked with working alongside Sheriff to solve it.
Jennifer appears to be a dedicated officer, but it soon becomes clear that she is one of the corrupt officers secretly working for Tony.
A reluctant mole
Jennifer is a single mother, and Tony takes advantage of her love for her son. He threatens her son’s safety to force her into working for him.

At work, Jennifer demands to be kept informed of every detail about the case and Tony’s gang so that she can pass this information on to Tony.
Her assistance allows Tony to stay one step ahead of the police, enabling him to get away with his crime repeatedly. Despite this, Tony does not trust Jennifer.
He keeps the location of his hideout and the identity of his other mole from her. Tony now wants Jennifer to find the Meth Killer, as the killer is targeting his associates.
When Sheriff starts suspecting Nazri, Jennifer tails him and discovers that he is indeed the Meth Killer. However, she keeps this information to herself.
She lies to Tony, falsely claiming that Syazlin is the Meth Killer, as she intends to join forces with Nazri. Unlike her fellow officers, Jennifer admires the Meth Killer for delivering justice to the corrupt.
She asks Nazri to trust her and help her take down Tony, revealing that she is being forced to work for Tony. She tells Nazri that he can do whatever he wants to her, but only if he kills Tony first.
Jennifer’s plan
Jennifer knows that she must tread carefully, aware that her son’s life is at stake. With Nazri’s help, she starts executing her plan.
She convinces Tony to kidnap Nazri and demand that Sheriff exchange the Meth Killer for their lives. Tony agrees, leading Syazlin to falsely confess to being the Meth Killer.
As the police track Syazlin to Tony’s hideout, Jennifer takes the opportunity to free Nazri. To maintain her cover, Jennifer kills people from both the police and Tony’s gang.
She also tries to kill Syazlin. However, Nazri intervenes and exposes the fact that Jennifer has been working for Tony to Syazlin.
Syazlin kills her brother to save Jennifer but is then shot by Inspector Farouk, Tony’s other mole. Jennifer subsequently kills Farouk to get rid of any witnesses or evidence of her crimes.
After the whole ordeal is over, Jennifer is seen as a hero because she claims that she shot Farouk in retaliation for Syazlin’s shooting.
Jennifer is credited with solving the case, but her troubles are far from over. She learns that Syazlin has survived and could reveal the truth about what happened.
Jennifer visits Syazlin in the hospital, intending to poison her, but before Syazlin can drink the poisoned water, Sheriff, who has always been suspicious of Jennifer, confronts her.
He tricks Jennifer into confessing her involvement with Tony. Knowing that she will now be investigated, Jennifer realizes that Tony’s associates will kill her son to silence her.
With no other option, Jennifer takes her own life. In her final moments, she warns Sheriff not to trust anyone and asks him to take care of her son, a request Sheriff honors.
