On the evening of April 14, 2015, 16-year-old Gail McFadgen was sitting on a wall outside a home on Diamond Street in Clearwater, South Carolina, when a drive-by shooting occurred at about 9 p.m. A single gunshot wound to her abdomen proved fatal and her death was ruled a homicide.

Authorities arrested 21-year-old Santonio Torez Williams of North Augusta in connection with the shooting. He was charged with McFadgen’s murder and pleaded not guilty; his trial was scheduled to begin in Aiken on January 31, 2017. Prosecutors said their case relied on witness accounts from the scene.

While jailed awaiting trial, Williams was indicted on additional charges alleging he attempted to obstruct justice: intimidating a court witness, accessory before the fact to a felony, and criminal conspiracy. Prosecutors said he had made a jail call in which he allegedly tried to arrange the murder of a witness, prompting a separate investigation by the South Carolina Law Enforcement Division.

Does anyone have information about Gail’s last hours or the shooting that could help clarify what happened?
