TEENS AND DRINKING, ON ABC NEWS' "20/20," FRIDAY, JUNE 5

From a party gone wild to a deadly drunk driving accident, "20/20" investigates two stories involving the explosive mix of teens and drinking. "20/20," airs FRIDAY, JUNE 5 (10:00-11:00 p.m., ET) on the ABC Television Network.

A night of drinking and partying at the house of a star infielder on the DeAnza community college baseball team in California's Silicon Valley led to scandal in early 2007. Was a 17-year-old high school girl sexually assaulted by the college athletes or was it consensual, as the baseball players maintained? Deborah Roberts' report includes interviews with three DeAnza women's soccer players who came to the alleged victim's heroic rescue.

Plus: Jessica Rasdall killed her best friend, Laura Gorman, when she crashed her car while driving drunk after a night of partying in 2006. In the three years since that fateful night, Rasdall has confessed her crime to more than 15,000 people, both young and old, in a speech that never varies, describing the minute details of that tragic night. Rasdall's story is a cautionary tale of love and loss, of overwhelming regret and remorse. Even as she tries to atone for what happened, she faces accusations of hypocrisy from the Gorman family, who say that her public speaking is merely an attempt to win leniency from the courts. She also has been accused of a pattern of dangerous behavior, of having mixed alcohol and driving in the past. Is she telling her story to save other teens, or is it a calculated speech to save herself from prison? Elizabeth Vargas reports.

"20/20" is anchored by Elizabeth Vargas and John Stossel. David Sloan is executive producer.
