A party involving teen drinking has led to the arrest of two Medford men, one charged with raping a 13-year-old girl, the other with encouraging child sex abuse.

Police arrested Glenn Edward Rise, 19, and Robert Raymond Person, 18, after the girl's father reported the crime on Aug. 20. Indicted Friday, both men remained in the Jackson County Jail on Monday.

Rise pleaded not guilty Monday in Jackson County Circuit Court to charges of first-degree encouraging child sex abuse, tampering with physical evidence, invasion of privacy and furnishing liquor to a minor. Person is scheduled to appear Wednesday in Circuit Court to hear charges of first- and second-degree rape, first-degree sodomy and unlawful sexual penetration and two counts of first-degree sex abuse.

The alleged victim, a Medford girl, attended an Aug. 3 party at the Stewart Avenue home of Rise and Person, said Medford police Lt. Tim Doney. There, Person gave her alcohol and sexually assaulted her, the girl told police. Rise reportedly photographed the act with his cell phone's digital camera feature, Doney said.

The girl's father heard about the attack about two weeks later and shortly after bumped into Rise and Person at Sherm's Thunderbird Market on Medford's West Main Street, Doney said. The man confronted the two and called police.

Rise stayed put, but Person ran through Sherm's to a storage yard behind the store, where he scaled a fence, Doney said. Officers soon arrested Person near the intersection of Winchester Street and South Columbus Avenue, initially charging him with disorderly conduct and criminal trespass. Rise was arrested Friday at his residence.

The circumstances under which the girl reported the crime to her parents were unclear, Doney said. It's not unusual in rape cases, however, for victims to keep quiet about the crime for an extended period of time, Doney said.

If convicted of the most serious crime, Person would be subject to a mandatory prison sentence of eight years and four months. His bail was set at $500,000 while Rise is in custody in lieu of $35,000 bail.
