Many people may recognize Devonte Hart after he was photographed hugging an officer in Portland, Oregon during a rally related to the 2014 protests in Ferguson, Missouri.

Now Devonte and two of his siblings have been reported missing after their family’s SUV went over a cliff.

According to ABC 7 News, the California Highway Patrol identified two adult women, Jennifer Hart and Sarah Hart, who were both 39. Authorities say their vehicle was driving on the “Pacific Coast Highway when it pulled into a dirt turnout and continued driving off the cliff.”

It was learned that the couple had six adopted children; three of their children were confirmed dead due to the crash.

A second search was arranged after it was realized that three additional children were still missing.

Devonte, 15, and his siblings Hannah Hart, 16, and Sierra Hart, 12, are still unaccounted for. At the moment it’s unclear if the children were with their parents at the time of the crash or if they were staying with friends.

The 2014 viral photo of Devonte hugging the officer was taken by Johnny Huu Nguyen.

Reportedly Child Protective Services recently visited the family’s home back in Washington, but when they entered the house they found no obvious signs of trouble or violence.
