AFTER BEING LURED INTO A DARK WORLD OF DOMINATION AND SEX, A COLLEGE STUDENT IS DEAD - WAS IT MURDER?

"48 HOURS: DANGEROUS GAMES"

Sept. 19, 2015

An innocent college student was lured into the dark world of domination and sex. She said no - twice - and now she's dead. Was it murder at the hands of a man with a taste for bondage and domination, or was it an accident?

Troy Roberts and 48 HOURS investigate the events leading to the death of University of New Hampshire sophomore Lizzi Marriott in an encore of "Dangerous Games" to be broadcast Saturday, Sept. 19 (10:00 PM, ET/PT) on the CBS Television Network. It's a case that explores the sinister side of BDSM - bondage and sadomasochism. It exposes a man who fantasized about murder and looks at the teenager who got caught up in his world for just one night.

In 2012, Marriott was enticed out for a night of fun by a friend. Little did she know that her friend, Kat McDonough, was bringing her home at the urging of her boyfriend, Seth Mazzaglia, who wanted the three of them to participate in BDSM - bondage and sadomasochism.

Authorities would later learn that night Marriott, McDonough and Mazzaglia watched a movie and played strip poker, leaving all of them in various stages of undress. Marriott was never seen again.

Three days after Marriott vanished, police called Mazzaglia and McDonough in for questioning. After lengthy interrogations, each told very different stories of what happened after that card game.

What really happened that night? The investigation would uncover some shocking twists, including another couple who saw Lizzi's dead body and then left the apartment.

Roberts and 48 HOURS piece together Marriott's life and final night alive through interviews with her parents, Melissa and Bob; her aunt and uncle, Becki and Tony Hanna; her friend, Nate McNeal; former Foster Daily Democrat executive editor Rod Doherty; as well as jurors from Mazzaglia's murder trial.

48 HOURS: "Dangerous Games" is produced by Sarah Prior, Sara Ely Hulse and Bruce Spiegel. Maria Barrow, Kevin Dean and Michelle Harris are the editors. Anthony Batson is the senior broadcast producer. Susan Zirinsky is the senior executive producer.
