"TEENS THESE DAZE" AIRS ON "20/20" FRIDAY, JANUARY 10

From a former college basketball star who faked her own kidnapping, to a teenager who returned home after a night of heavy drinking - to the wrong home, "20/20" reports on the pressures and sometimes deadly decisions of teenagers. "20/20" airs FRIDAY, JANUARY 10 (10:01-11:00 p.m., ET) on ABC. Reports include:

· One night last spring, 16-year-old Caleb Gordley snuck out of his house to party with some friends a few blocks away. At 2:30 in the morning, a drunk Caleb walked to what he thought was his house, but he mistakenly entered the wrong house. The startled homeowner - awoken by his alarm -- thought a burglar had entered his home and grabbed his gun and fired two warning shots. When those were unheeded, he fired two more shots and killed Caleb. Was the shooter justified in killing Caleb? Deborah Roberts speaks to Caleb's parents, who are outraged, and to the sheriff in charge of the case.

· From coast to coast, the big party invites are posted on social media sites, quickly turning 40 guests to 400. But there's a new sheriff in town... LA County's E-COMM unit monitors social media on Friday and Saturday nights to find the parties before they spiral out of control. ABC News Correspondent Gio Benitez rides along with the unit, armed with tips they've found online. For these teens, nothing's a bigger buzzkill than a bunch of cops.

· When 18-year-old Cece Sims, a basketball standout on a full ride scholarship at Auburn University, went missing, everyone thought the worst. Local authorities put on a full court press to find the former homecoming queen, gifted athlete and aspiring musician whose father is a Grammy-winning composer. But when they do, they are astounded to learn they were on a wild goose chase. Were the pressure and excesses of college life too much for Cece Sims to bear? Mother and coach speak exclusively to Deborah Roberts about how Cece tried to escape her own life.

· More than ever, body image is as much an issue for teenage boys as it is for girls. From marketing to movies, the overwhelming message is that boys must have broad shoulders, toned arms and six-pack abs. Matt Gutman meets one boy who is taking that to the extreme. Jake Schellenschlager is a 14-year-old body builder and powerlifter who has won five competitive titles. "The Wonder Kid" can lift more than twice his weight -- some 300 pounds -- a feat that impresses powerlifting aficionados and worries pediatricians who believe this kind of workout regimen poses risks to developing bodies.
