''Of all the people seen on video footage seized from nearby security cameras that night, this person is the only one detectives have been unable to identify and exclude from the investigation, Det. Sgt. Brandon Price said at a news conference at Toronto police headquarters on Tuesday.
"We have been able to eliminate the vast majority of people captured on the video," said Price. "We are left with one individual, whom we have been unable to identify."
Price said police are suspicious of the person's activities because they walk into a "defined area" not captured by video surveillance, stay there for a while, and then leave.
"Through our investigation, we have been unable to determine what this individual's purpose was in the neighbourhood. The timing of this individual's appearance is in line with when we believe the murders took place," said Price. "Based on this evidence, we are classifying this individual as a suspect."
Price said video analysis shows the individual is 5'6" to 5'9" tall, but the person's sex, race and other identifiers cannot be determined.
The video shows the person walking with an unusual gait, where they kick up their right foot with every step.''
