How you can become a 'Dateline Detective'

If you are reading this blog, you are most likely a big fan of the show and we want you to become an official "Dateline Detective."

All you have to do is log on to Tunerfish.com/Dateline during tonight's mystery broadcast at 10:00P/ET and share out to Facebook and/or Twitter that you are watching to earn our special badge.

"Dateline" Executive Producer David Corvo says: "We're always looking for new and creative ways to engage our viewers and enhance the storytelling experience for our loyal fans. 'Dateline's' mysteries are about justice being delivered and we hope our audience takes advantage of this opportunity to feel part of that process."

Monday's mystery looks into the murder of 28-year-old Melissa Mooney, who was discovered dead in her home in August 1999. The FBI spent years trying to find the murderer because Melissa was one of their own -- she worked for the FBI in Wilmington North Carolina as an office manager. Correspondent Josh Mankiewicz interviews the FBI agents who wouldn't give up trying to get justice for Melissa and reports on the ending that surprised them all.
