20/20

Nearly two decades after Michael King was convicted for the murder of 21-year-old mother Denise Amber Lee, he was executed in March with Denise's husband and son in attendance. This Friday, "20/20" revisits the case of this young mother who was kidnapped and murdered following a series of chilling 911 calls, including new interviews with Denise's husband and son following that execution. "20/20" co-anchor Deborah Roberts reports.

In 1989, 11-year-old Jacob Wetterling was biking home with his brother and best friend when a masked, armed man abducted him just a half mile from his home. This Friday, "20/20" reports on Minnesota's most notorious kidnapping case and speaks to Jared Scheierl, who at age 12 was abducted by the same man who would kidnap Jacob Wetterling months later. DNA found on Scheierl's clothing led authorities to a suspect who made a stunning confession 27 years later. Co-Anchor Deborah Roberts sits down with Jacob's parents, Patty and Jerry Wetterling, as well as blogger Joy Baker, whose research helped push for a new review of the case.
