ROGUE RIVER — Two 16-year-olds face criminal charges after they allegedly beat up a 15-year-old Josephine County runaway at a drinking party.

Rogue River police on Wednesday arrested the 16-year-olds on charges of fourth-degree assault, strangulation and criminal mischief after hearing the tale of the blood-covered 15-year-old.

The older teens are lodged in the county juvenile detention center in Medford, said Rogue River police Chief Ken Lewis.

The younger teen, missing 10 days before police found him Wednesday, is back with his grandparents, with whom he lives.

Lewis said police received multiple calls early Wednesday of a teenager staring in windows of cars parked in the area of Fourth and Broadway streets.

Lewis said he found the boy but the boy ran, prompting a two-hour search that ended when officers chased the boy and caught him near Rogue River Elementary School.

The bloodied boy told officers he'd been assaulted at a party at a vacant home on Magerle Lane.

One of the assault suspects, who is the grandson of the property owner, hosted several juveniles at a drinking party at the home, which is for sale, Lewis said.

The boy and another teen told police they assaulted the victim when the victim became belligerent and refused to leave the home, Lewis said. Investigation by police resulted in the arrest of the 16-year-olds, Lewis said.
