Police now have a suspect in the killing of a 61-year-old woman who operated a dry cleaning business in Scarborough.

The image of the suspect was captured by a security camera outside Top A Drycleaners – the shop where police discovered the body of Rose Liu on May 10.

Earlier, the woman had been called a "person of interest."

Det. Scott Whittemore said that the woman seen in the photo should call police immediately.

The woman in the video is described as being between 25 and 30 years old. She was wearing a long, dark coat and her hair in a bun.

Son Stephen Liu said his mother's death has left the family and the community reeling.

"Turn yourself in," the son said. "It's your only chance of redemption. You've taken so much from us."

The woman's husband also issued an emotional plea for the suspect to come forward.

"Help us identify my wife's killer," Michael Liu said. "She deserves justice."

Police have speculated that a botched robbery may have led to the killing.
