Investigators have released a criminal profile of the person they believe may have randomly killed a Burnaby, B.C., teenager last summer.
Marrisa Shen, 13, was found dead in the city's Central Park in the early hours of July 19. She'd been reported missing the night before.
RCMP and the Integrated Homicide Investigation Team said Shen's death was a random attack, but a suspect has never been identified.
On Tuesday, IHIT said criminal profilers believe the attacker may have lived in the area around Central Park at the time.
A statement said he or she may have behaved in the following ways after the teen's death:
Moved unexpectedly, permanently or temporarily
Uncharacteristically avoided the Central Park area
Withdrew from family or social activities
Missed work or scheduled appointments
Showed suicidal gestures or made attempts
Seemed particularly interested in media coverage releated to Shen's death
Increased or decreased their use of drugs and/or alcohol
IHIT Cpl. Frank Jang said there is still strong public interest in the case and anyone who recognizes the characteristics or behaviours in someone they know or knew should contact police.
"This was a random attack. I know that's unsettling to all of us,'' he told reporters on Tuesday.
