PORTLAND, Ore. -

A retired Warm Springs police officer, Head Start teacher and child protective services worker faces up to 10 years in federal prison and a lifetime of supervised release after his conviction on charges of abusing five young girls, prosecutors said.

Harry Hintsala, 62, of Warm Springs, was found guilty Wednesday of five counts of abusive sexual contact after a trial before U.S. District Judge Michael Mosman.

Hintsala pleaded not guilty to the charges, but he waived a jury trial and stipulated that the facts presented by the prosecution at trial were sufficient for Judge Mosman to find him guilty beyond a reasonable doubt, prosecutors said in a news release Thursday,

Mosman scheduled Hintsala?s sentencing hearing for June 25. Until then, he is required to reside at a halfway house pending sentencing, is prohibited from having any contact with minors, and must wear a GPS monitoring bracelet at all times.

He faces a maximum sentence of 10 years in prison, to be followed by a lifetime of supervised release.

?Mr. Hintsala?s abuse of these young girls not only violated the victims and their families, but also violated the trust of the Warm Springs community,? said Amanda Marshall, U.S. Attorney for Oregon.

?This office will continue to work with tribal police, tribal protective services and federal investigators to ensure that tribal children are protected from all forms of abuse,? Marshall added.

According to the evidence and testimony presented at trial, Hintsala sexually abused five girls at his residence on the Warm Springs Indian Reservation between 2007 and 2011. The victims were approximately 8 to 12 years old at the time of the abuse.

Hintsala is a former Warm Springs police officer, and he had previously worked as a supervisor at Warm Springs Children?s Protective Services and as a teacher at Head Start.

Prosecutors said all of the sexual abuse in this case occurred after Hintsala had retired from those public positions.

Under a sentencing agreement signed by Hintsala, both he and the government will recommend that Mosman impose the maximum sentence of 10 years in prison.

This case was investigated by the Warm Springs Police Department and the Bend FBI office. The case was prosecuted by Assistant U.S. Attorney Craig Gabriel.
