�PRIMETIME� INVESTIGATES WHETHER A MYSTERIOUS DEATH WAS AN ACCIDENT OR MURDER, AIRING THURSDAY, JUNE, 22 ON ABC

Did Mark Unger Push His Wife Over the Edge, or Did She Fall?

Florence Unger was 37, a wife of 13 years, and mother to two sons when she was mysteriously found dead in a northern Michigan lake. In October 2003, the Unger family -- Florence, her husband, Mark, and their two young sons -- made a familiar four-hour drive from their Michigan home to an area they frequented in Lower Herring Lake, MI. But this wasn�t just another trip for the family; the Ungers were in trouble. Mark recently finished rehab for alcohol and gambling addiction, Florence was having a secret affair with one of his best friends, and the couple was on the verge of divorce. Friends say Mark convinced Florence the weekend away would be good for the family. The night of Florence�s death, she and Mark were seen on a deck, and the next morning she was found 12 feet below that same deck, her body laying face down in water. But did she fall or was she pushed? Her husband is the only suspect, and he allowed �Primetime� to record a revealing video diary about the fight of his life. John Qui�ones investigates the suspicious death, as �Primetime� goes inside the twists and turns of the dramatic trial, with a verdict that was just announced today. �Primetime� airs THURSDAY, JUNE 22 (10:00-11:00 p.m., ET) on the ABC Television Network.

DIANE SAWYER, CHRIS CUOMO, CYNTHIA McFADDEN and JOHN QUI�ONES are the anchors of �Primetime.� DAVID SLOAN is the executive producer.
