On Oct. 24, 2011, 12-year-old Garrett Phillips was murdered in his home in Potsdam, a small town in upstate New York. Police quickly zeroed in on a suspect in this unthinkable crime: Oral “Nick” Hillary, a black man in the mostly white community, who was a soccer coach at Clarkson University and the ex-boyfriend of Garrett’s mother, Tandy Cyrus. From two-time Academy Award-nominee and Emmy-winner Liz Garbus (HBO’s A Dangerous Son and Nothing Left Unsaid: Gloria Vanderbilt & Anderson Cooper), the absorbing two-part documentary Who Killed Garrett Phillips? looks at the case from the initial investigation through the arrest and numerous legal twists and turns that culminated in Hillary’s trial for murder five years after the crime. The two-part documentary raises troubling questions of racial bias and issues surrounding policing and the criminal justice system.
