Images have been released of a suspect accused of shooting two people at a west-end Toronto apartment building on Tuesday.

Gunshots rang out on the sixth floor of a building at 50 Lotherton Pathway shortly after 9 a.m.

Toronto police arrived to find a woman and a man with critical wounds. Investigators have described the ordeal as “targeted.”

Both were rushed to hospital. The woman is said to have sustained “life-altering injuries” while the man’s condition has improved to non-life-threatening.

Sources confirm to CTV News Toronto that the victims are 24-year-old Mark Dookhram and 47-year-old Shimoon Jhagroo, who are mother and son. Investigators have described the incident as “targeted.”

Police said that Jhagroo’s injuries will likely leave her blind.

In 2015, Dookhram was charged with first-degree murder in the death of Teresa Hsin, who was found stabbed to death in her BMW in Mississauga. Two other men, identified as Justine Ordonio and the victim’s son Eric Lu, were also charged in the murder.

The murder trial for Lu is set to start on March 18.

Tuesday’s shooting brought members of Toronto police’s emergency task force to the residential neighbourhood. Officers were seen combing the vicinity of the building for evidence. Much of the area was cordoned off for several hours.

The suspect was previously described as a black male wearing all black clothing.

In the three photos released on Wednesday, the suspect seems to be wearing a hooded jacket and baseball cap, as well as a black backpack. In one of the images, he appears to have something covering his mouth.

Anyone has information about the suspect or shooting is being asked to contact Toronto police or Crime Stoppers anonymously.

UPDATE on Feb. 25, 2019: A previous version of this story incorrectly reported that the charges against Dookhram have been dropped.
