Winnipeg police have released new information that investigators hope will help lead to tips in the unsolved homicide of a Winnipeg woman.

Simone Sanderson, 23, was found dead on Sept. 2, 2012 in the area of Main Street and Burrows Avenue. Her body had been concealed, police said.

While Sgt. Wes Rommel, a detective with the Winnipeg Police Service, said progress has been made in the case and the investigation is still ongoing police are now looking for help identifying a suspect.

"Her family and friends want and deserve justice as do our entire community," said Sgt. Rommel.

He said investigators were able to get a description of the vehicle through a combination of surveillance and tips from the public.

"We are looking specifically for a male who uses sex-trade workers and who in 2012 drove a small, two-door car, older model."

Police now want the public's help identifying the suspect operating the vehicle. Sgt. Rommel said there are indications the suspect returned to the crime scene following the homicide. He also said police have developed a male DNA profile which detectives believe will be key in identifying the suspect.

Sgt. Rommel said Sanderson was struggling with addiction and was working in the sex trade at the time of her death.

Members of Sanderson’s family objected to the police releasing this information. “We are not listening to the Winnipeg Police Service,” Betty-Ann Sanderson said in a Facebook post.

She didn't want investigators to "label" her granddaughter a sex-trade worker, and she’s turned elsewhere to find answers.

"I know that she's hired a private investigator to get answers for her to make some inquiries. In terms of that need, clearly she felt the need to do that I can't really speak further to that,” said Sgt. Rommel.

He said investigators believe the suspect still resides in Winnipeg and need the public's help identifying the man.

"We're looking for a name, an individual who was at that scene,” said Sgt. Rommel. “We're looking for someone who has a suspicion about that person, something they saw that night."

Anyone with information is asked to call the Winnipeg Police Service at 204.986.6508 or Crime Stoppers at 204.786.TIPS (8477).
