Back in 2014, a picture of a Devonte Hart, tears streaming down his face and gripping a white police officer in an embrace during Ferguson-related protests, went viral. But now Devonte is missing and feared dead after his parents and three of his siblings were killed in a car crash. On Monday, a passerby spotted the family’s vehicle flipped onto its roof in the Pacific Ocean at the bottom of a 100-foot cliff in a rural part of California’s Mendocino County, according to officials. Devonte’s parents Jennifer and Sarah Hart, both 38, were both found dead inside the S.U.V., rocked by waves washing in and out, say police. Three of their children: Markis, 19, Jeremiah, 14, and Abigail, 14 were recovered outside the vehicle. However Devonte, now 15, and his two sisters Hannah, 16, and Sierra, 12, remain missing, say police. Mendocino County Sheriff Tom Allman said at a press conference Wednesday that while police cannot say with certainty that Devonte, Hannah and Sierra had been in the vehicle, “We have every indication to believe that all six children were in there.” Police are seeking the public’s to help in piecing together the family’s final 24 hours before the crash. The Harts are from Woodland, Wash.
