The OPP say the two killers of Henry Stone-Arnold and an accomplice are all in custody, but they cannot be named as they were under the age of 18 when they allegedly murdered the man.

Two individuals are facing charges of:

- First Degree Murder,
- Committing Indignity to a Body,

A third individual is facing charges of:

- Obstructing Justice,
- Uttering Threats,
- Accessory After the Fact (murder),

The then 28-year-old Stone-Arnold of Dryden was reported missing on August 10, 2018, after being seen alive at the Husky Gas Bar on August 8 in Dryden. His white, 4-door Dodge Ram was suspiciously found at a local business the following day.

''The last time Stone-Arnold was seen alive in the Dryden area. 

After an extensive search, Stone-Arnold’s remains were found on private property off of Trist Road by August 17, about 1 kilometre away from the site of his abandoned vehicle. At the time, police noted his body was ‘intentionally damaged’ after death and confirmed foul play had been a factor in his death.

Now, the OPP say they believe the three accused and Stone-Arnold were known to each other.

Notably, Stone-Arnold was involved in a small methamphetamine bust in Sioux Lookout just 8 days before he was reported missing, and police have never confirmed if those charges were a factor in his death. The OPP add their investigation will continue.

"For the last 46 months, our investigative team has worked diligently to identify those responsible for Henry's murder. Although we cannot publicly identify the charged individuals, there is some consolation in being able to bring resolution to Henry's family and loved ones,” said Detective Inspector Kevin Keillieux with the OPP.

The resolution to Stone-Arnold’s investigation comes just one day after police made two arrests in the Alyssa Turnbull murder investigation. The OPP have now made significant progress in two of five unsolved death investigations in northwestern Ontario.

The other three cases include Richard Roach who was killed in Sioux Narrows in February of 2015, Susan Assin who was found murdered in 1974, and Kenora’s ‘Millie’ Jane Doe of 2009, an unidentified body found by a hiker in a small tent near Rapids Road.

The OPP say they never close an unsolved homicide and the file is considered active until it’s resolved. Anyone with any information related to the case is asked to contact the OPP at 1-888-310-1122 or Crime Stoppers at 1-800-222-8477 (TIPS).
