Toronto Police Detective Sgt Gary Giroux spoke at a press conference on Monday, updating the death of Nikki Semret in Cabbagetown.

The 55 year old Semret was stabbed to death one week ago on Monday, while walking home from her job as a cleaner at the Delta Chelsea.

Police still haven't made an arrest.

They have released more videos on youtube, showing different angles, Semret and the suspect walking along the street, in the moments before and just after the attack.

The suspect is described as a white male, about five-foot-10 to six-foot-two, 150 to 200 pounds, with a medium build. The

surveillance video, uploaded to YouTube, shows him wearing a dark coat, a light-coloured scarf and a dark hat.
