A Saskatoon man accused of putting GPS trackers on vehicles now faces 102 charges.
Forty-six-year-old Marty Schira was already facing multiple charges including mischief, intimidation and fraudulent concealment.
The investigation began in early September 2024 when a man showed up at the police station after finding two trackers on his vehicle.
The investigation led the police to execute a search warrant at an apartment in the 2000 block of 20th Street West, where they arrested Schira and located several other trackers.
In January, police issued a public plea asking people to check their vehicles for the devices.
Now, police say they’ve discovered 14 trackers involving 24 victims and the investigation continues.
After the story came out in January, one alleged victim told CTV News he believes his girlfriend was one of Schira’s targets.
Daelyn Boettcher said he was servicing the brakes on his truck in September when he noticed something under the fender that didn’t belong.
“I just so happened to look up and see,” he told CTV News in an interview. “‘What the hell is that?’”
He found what turned out to be a GPS tracker — a little black box with a SIM card that runs on the cellular network — fixed to his fender with black duct tape. He took it to the police.

Boettcher had seen similar devices before. In December, he pleaded guilty to mischief and criminal harassment for installing a GPS tracker on a woman’s vehicle in 2023. He received an absolute discharge.
Schira was convicted of sexual assault and kidnapping in 2004 for abducting a woman from Rosetown, Sask. and tying her up in his Calgary apartment.
Schira was sentenced to 14 years in federal prison.
Parole Board of Canada documents obtained by CTV News show Schira committed a number of violent acts while incarcerated. In 2011, he hit a fellow inmate at the Regional Psychiatric Centre in the head with a coffee pot, unprovoked, according to the parole board.
In March 2014, Schira was convicted of assault with a weapon and sentenced to two more years after stabbing a correctional officer in the forehead with a protractor, and twice in the hand.
Throughout his incarceration, the Parole Board of Canada elected to keep Schira behind bars. They repeatedly found he showed little accountability for his actions or insight into the risk factors for his offense.
