Cops said the suspect is facing several charges that include first-degree murder, arson and indignity to a body.

They also said the arrest does not close the book on the case, as the Dufferin detachment continues to investigate the circumstances surrounding Robson’s demise.

“While an arrest has been made in connection with the homicide of David Robson, we believe other individuals may be involved,” Det.-Insp. Mark Allison said in a news release. “We continue to urge anyone with information to contact police.

“Our goal is to hold all those responsible for David’s death accountable and provide answers to his family.”

Billboard posted last month by cops

The arrest came almost exactly a month after the OPP issued a fresh appeal for information on Robson’s slaying and posted a billboard outside of Orangeville featuring a picture of him and his Kia Sportage SUV in a quest to gather new tips from the public.

Allison said at the time that cops wanted to “understand what happened to David and provide the answers his loved ones have been waiting for over the past two years.”

An email seeking a comment from the OPP on whether the appeal helped lead to the identification of the suspect was not immediately returned.

Body found in April 2024 near Brampton

Robson was reported missing from Melancthon Township on March 25, 2024, when his residence was also reported to be on fire, before his body was found a week later in the Chinguacousy Rd.-King St. area of Caledon, which is just a few kilometres northwest of Brampton.

Police said a post-mortem examination conducted the next day determined that Robson’s death was the result of a homicide, which was being probed by the Dufferin OPP crime unit under the direction of the OPP’s criminal investigation branch.

The OPP said at the time that they did not believe there was a risk to the public’s safety as they did not consider Robson’s death to be random.

Police continue to urge anyone with additional information on the case to contact them at 1-888-310-1122 or Crime Stoppers anonymously at 1-800-222-8477 or ontariocrimestoppers.ca.
