Prosecutors in Colorado on Monday dropped child sexual assault charges against the brother of former NAACP Spokane chapter president Rachel Dolezal. Rachel’s brother, Joshua Dolezal, was facing four counts of child sexual assault by one in a position of trust, reports said Tuesday. A trial for the case was originally set for August.

Joshua was accused of assaulting a female sibling when she was 6 years old between 2000 and 2001 in Clear Creek County, Colorado. The victim had also said that Joshua abused another person. However, their mother claimed that the allegations were a malicious lie and that they were initiated by Rachel, who had allegedly lied about her race for years. Joshua is an English professor at Central College in Pella, Iowa, People magazine reported. 

"My family and I are grateful that these false allegations have been dismissed and that justice has prevailed,” Joshua told People, adding: "We are thankful to our family, friends, neighbors, and colleagues who have supported us throughout this ordeal, and we are so happy to once again face the future with hope.

"The court's decision to dismiss the false charges against Joshua is an appropriate acknowledgement of his innocence. We are sincerely thankful that justice has been done."

Rachel -- who was born white, but identified herself as a black woman -- courted controversy last month when her mother Ruthanne said that Rachel began to “disguise herself” after the family adopted four African-American children. The contentious issue also led to Rachel’s resignation from the Spokane chapter on 15 June.

“It was very noticeable,” Rachel's father Larry said, in an earlier interview last month, adding: “She loved the black people and embraced black as beautiful.”
