ALCOHOL, A HIGH SCHOOL PARTY, AND A HE-SAID-SHE-SAID DIVIDES A SMALL ALABAMA TOWN

'20/20' Airs on the West Coast on Saturday, Sept. 8 (10:00-11:00 p.m. PDT), on ABC

A night of underage drinking led to two lives forever changed and an Alabama town divided. Eighteen-year-old running back Cameron Harrison was charged with first degree rape of Savannah, a 16-year-old classmate, after a police investigation into a high school party on Oct. 24, 2015. In an interview with ABC News correspondent Ryan Smith, Savannah speaks about the party and what happened afterward. The "20/20" report also includes interviews with Savannah's parents; students who were at the party; and Detective Jason Vannoy of the Daphne Police Department, lead investigator on the case. Due to the college football broadcast schedule, "20/20" airs only on the West Coast on Saturday, Sept. 8 (10:00-11:00 p.m. PDT), on ABC. (Rebroadcast. ABC OAD: 6/2/17)

Multiple witnesses claim Savannah was "very intoxicated" at the party and cell phone video shows four people carrying her upstairs. Other witnesses from the party tell a different story, saying that although Savannah had been drinking, she was coherent, laughing, walking and speaking. The case came down to whether Savannah gave consent or not. After the party, Harrison was suspended from school and football, and placed on house arrest. The investigation divided the town: Harrison's friends supported him while others stood behind Savannah.

After 18 months, the case concluded in a manner that surprised many.
