It was a deadly weekend with five murders across the GTA.
The latest murder victim is an elderly man in Richmond Hill, who was found dead in a home on Harding Boulevard near Yonge Street and Major MacKenzie Drive, just after 9:00 p.m. Sunday.
A family member found the man with obvious signs of trauma and contacted police.
York Regional Police are now looking for the son of the deceased man, who has been identified as 77-year-old, Robert Veltheer.
Investigators want to speak with his 30-year-old son, Jacob Veltheer, who may have been the last person to see him alive.
