A 6-year-old boy is dead and so is his father, in what appears to be a murder-suicide in East York.
Toronto Police were called to a home near Broadview and Gamble, south of O'Connor on Monday night around 7 o'clock.
Officers say it was a neighbour or a passer-by who made the initial 9-1-1 call, which was originally for a medical incident.
They haven't released a cause of death for either of the victims but say the boy was found with obvious signs of trauma.
The victims have been identified as Zlatan Cico, 58, and Simon Cico, 6, of Toronto.
"There are no outstanding suspects, so we believe the male to be responsible for it." says Constable Allison Douglas-Cook from Toronto Police.
The boy lived in the home with his mom.
