Medford police said today that 50-year-old Aaron Friar was allegedly killed by his juvenile daughter, her adult boyfriend and another adult male.

Friar, who lived in the 500 block of Benson Street in Medford, was found dead Monday afternoon where he had been dumped over a dirt embankment in the 9100 block of East Antelope Road. Police said Aaron Friar was assaulted and killed "with a weapon" while he was sleeping Monday morning. The suspects then allegedly stole his vehicle to transport his body to East Antelope Road.

"We are confident that it occurred early Monday morning," said Medford police Lt. Justin Ivens. "We can't say which weapons were used right now — but it could be several."

Friar's daughter Ellen Rose Friar, 15, was arrested Monday along with Gavin Curtis MacFarlane, 19, and Russell Pierce Jones II, 22.

Detectives searched MacFarlane's house on Almond Street Monday night, according to the release.

Detectives said in a press release that Ellen Friar and MacFarlane were involved in a sexual relationship, which had caused tension between the victim and his daughter and her boyfriend. Ivens said Jones is a friend of MacFarlane.

According to their Facebook pages, Ellen Friar goes to South Medford High School and plays in school band; MacFarlane also went to South Medford High School until this year. He had started classes at Rogue Community College this fall. Medford School District officials declined to comment on those involved.

MacFarlane is also a member of Circle Youth Ministries on Facebook and appeared in pictures of the Junior High-College ministry at Joy Church Medford.

Jones' Facebook account shows he went to Crater High School in Central Point and is "self-employed."

MacFarlane and Ellen Friar don't have any prior criminal record in Oregon, court records show.

Jones was convicted in 2014 of third-degree sexual abuse in Yamhill County involving a child younger than 16, court records show. Jones was sentenced to five years probation and ordered to complete evaluation and treatment. He lived in Central Point at the time, according to court records.

The trio was arraigned Tuesday and scheduled for preliminary hearing Oct. 10 for charges of murder, first-degree robbery, conspiracy to commit murder and a misdemeanor charge of tampering with evidence. MacFarlane was also charged with first-degree rape.

Ellen Friar was lodged in Jackson County Juvenile Detention Facility but also appeared in court Tuesday.

An autopsy is pending to assist in determining the cause and manner of death, the release said.
