Marcin Sydor did not age well. In fact, there will be no more aging of any kind for the Hamilton man. Detectives say Sydor — who vanished on April 21, 2026 — was murdered, and their probe into his disappearance has become a homicide investigation. The end of the line for Sydor came at the age of 48.
Floating in Hamilton Bay
On May 27, police issued a media release stating they were “concerned for his well-being.” On Friday, a Stelco employee discovered Sydor’s body floating in Hamilton Bay near Pier 16. A post-mortem examination determined that Sydor had been murdered. Police said in the release that Sydor was driving a family member’s black 2014 Volkswagen Jetta with tinted windows.
At a press conference on Monday morning, detectives were tight-lipped about how Sydor died. Detective John Overback stated that Sydor was known to police and had used several aliases in the past. He refused to elaborate on Sydor’s past interactions with law enforcement. “The cause of death and details surrounding his injuries are not being released at this time in order to protect the integrity of the ongoing investigation,” police said in a news release.
Trouble in Halton
In 2015, the Halton Regional Police’s Burlington office sought the public’s help in locating Sydor for a series of crimes. According to police, in March 2011, Sydor entered a residential parking lot in Burlington and stole a vehicle, then proceeded to damage and steal from several vehicles parked overnight. He was also accused of stealing various items, including four tires and rims from a car, GPS units, and credit cards from inside the vehicles.
Additionally, Sydor was accused of breaking into and stealing items from several storage lockers. He made the wanted list after failing to appear in court in February 2012. At that time, he was also wanted by Hamilton police for 29 counts of possession and use of a credit card, seven counts of fraud under $5,000, two counts each of breach of an undertaking and failure to comply with recognizance, and one count each of fraud over $5,000 and breach of probation. It is not clear what the outcome of the charges against the Polish-born Sydor was.
And now, he is dead. “Marcin’s disappearance prompted an extensive missing person investigation. Investigators pursued numerous avenues in an effort to locate him after his absence was reported and quickly determined that his disappearance was out of character and inconsistent with his usual behaviour,” the press release stated.
