Untraceable is a 2008 American psychological thriller film directed by Gregory Hoblit and starring Diane Lane, Colin Hanks, Billy Burke, and Joseph Cross.

At night, she works in the FBI's cybercrime division with Griffin Dowd, fighting identity theft and similar crimes.

At a press conference, the public is urged to avoid the website, but as Jennifer feared, this only increases the site's popularity.

After the killer leaves the room, Griffin uses his dying moments to blink a message in morse code, giving the FBI the lead he was following up on.

Jennifer follows up on the morse code message to discover that the victims were not random: they were involved in broadcasting or presenting the suicide of a junior college teacher.

The teacher's unstable techno prodigy son, Owen Reilly, broke down and was admitted to a psychiatric hospital.

When released, he decided to take revenge and prove a point: that the public's interest in the suffering of others is insatiable, as well as to wreak vengeance on those he felt had exploited his father's death.

She breaks free and pins down the murderer, fatally shooting Owen as the police arrive.

The birthday party for Perla Haney-Jardine's character Annie was filmed in the roller skating rink of Oaks Amusement Park.
