UPDATE: Man charged in underground PATH stabbing makes court appearance

A 19-year-old man accused of stabbing a woman to death in Toronto's underground PATH network has appeared in court.

Duncan O'Neil Sinclair of Toronto is charged with first-degree murder in Wednesday's attack.

He made a brief court appearance this morning, the day after police say they arrested him in Midland, Ontario, more than 100 km north of the city.

51 year-old Rae Cara Carrington was found with apparent stab wounds in the Commerce Court food court underneath King and Bay streets on Wednesday.

Police say the attack was targeted, but they would not comment any possible link between the victim and suspect.  Several media outlets have been reporting that they are mother and son.

The stabbing was not far from where Rosemarie Junor was fatally stabbed in 2015 by Rohinie Bisesar, who was found not criminally responsible for the attack last year.
