Prosecutors in Oregon have charged a 25-year-old woman with beating her 4-year-old son to death because she feared he was gay.

The boy, Zachary Dutro-Boggess, died in 2012, several days after being hospitalized with trauma to his abdomen.

Prosecutors allege that Jessica Dutro was abusive with three of her children, but Zachary bore the brunt of the violence. Only an infant – whose father Dutro lived with – showed no signs of abuse.

Dutro's 7-year-old daughter told investigators that her mother and her boyfriend had beaten her brother before he died.

Using a slur, Dutro told her boyfriend in a Facebook message that her son was going to be gay – “He walks and talks like it. Ugh.” – and said that he would have to “work on” Zachary.

Dutro is charged with murder, murder by abuse and second-degree assault, The Oregonian reported.
