Police arrested a Washington couple this week on homicide by abuse and assault charges months after their 13-year-old adopted daughter was found dead at their residence.

Larry P. Williams and Carri D. Williams’ adopted daughter Hana, who was adopted from Ethiopia in 2008 and came to America in search for a better life, was found in the family’s backyard in Sedro Woolley, Wash. naked and face down in mud in May.

According to court documents, the teen was systematically beaten, starved, forced to shower outside, sleep in a barn and use an outdoor toilet as punishment for being “rebellious”.
