Richard Koca, founder of charity "Stand Up For Kids," arrested for sexually assaulting child, say Colo. police

(CBS) AURORA, Colo. - The founder of a children's charity was arrested last weekend on suspicion that he sexually assaulted an Aurora child under his supervision, CBS Denver reports.

Aurora police Sgt. Cassidee Carlson said officers arrested 69-year-old Richard Lee Koca Sr. Saturday on charges of sexual assault by a person in position of trust. Koca is the founder, former CEO and a current board member of Stand Up For Kids, a national nonprofit volunteer outreach organization for at-risk homeless youth.

"Due to Koca's extensive contact over the past several decades with persons under the age of 18 through his work with several nonprofit organizations that primarily serve children, there are concerns that there may be additional victims," Carlson said in a statement.

Carlson said Koca served in the Navy and visited locations around the world. Police said there's a possibility some victims could be from his time in the Navy and requests anyone with more information to call Aurora police.
