Mark Foster was the prime suspect of the rape and murder of Lynn Rivers, along with four other rapes. One of his rapes was attributed to Victor Tate until 2009, while two others went undetected because the victims were prostitutes.

After confessing to all of the crimes, Foster commits suicide by falling from a high-story window at the SVU precinct. Because he never officially testified in open court, Tate was to continue serving his sentence. (SVU: "Unstable")
