The body of Tricia Boisvert was found in the woods northeast of the village of Quyon, Que., on Jan. 23. She had disappeared from her home in Montreal a week earlier.
A Canada-wide warrant has been issued for the arrest of Philippe Steele Morin of Gatineau. He is facing a charge of second-degree murder.
Melanie Boisvert distributed flyers with the suspect's image in the Byward Market over the weekend. An arrest in the case will help the family heal, she said.
"The family is having a hard time. Definitely, the hardest part is knowing that he's still out there. What we want is justice for her murder," she said.
Morin has short, brown hair and blue eyes. He is five-foot-seven and 161 pounds. He has an eagle tattoo on his left arm and a dragon tattoo on his right arm.
Montreal police are leading the investigation but believe Morin is in the Ottawa or Gatineau area. Anyone with information about Morin is asked to call Info-Crime Montreal at 514-393-1133.
An anonymous donor is offering a reward of up to $5,000 for information leading to an arrest and conviction in Boisvert's death.
