Hamilton police arrested one man in the slaying of McMaster student Tyler Johnson and are hoping security video can identify two more suspects connected with a shooting they now call targeted.

Johnson, 30, was shot dead at a King St. W. plaza near Hess Village around 3 a.m on Nov. 30. Police said there was an altercation that quickly got out of hand, before one suspect produced a handgun and shot Johnson.

Johnson was taken to hospital but died from his injuries.

Police said they are still looking for a motive in the case, and are looking to identify a series of men who were either with the shooter or victim that night. Police are asking for the public's help in identifying the following people based on the surveillance videos, one of which is embedded here and the rest which can be seen on Hamilton Police's YouTube channel.

  • A white male suspect wearing a blue jacket and red hoody.
  • A white male suspect in a black hooded jacket.
  • A white male suspect in a light shirt, black vest, baseball hat and jeans.
  • A white male person of interest, wearing a black jacket, blue jeans and white shoes.
  • A white male person of interest, wearing a Puma shirt, black jacket with the letters "GRRC" on the back and blue jeans.
  • A white male person of interest, wearing a red baseball hat, blue jeans and high-top shoes.

The men were captured on a series of surveillance videos from nearby restaurants. The plaza, which has a Tim Hortons, pita restaurant and convenience store, has been the site of violence before, including another homicide earlier this year in which a teenager was stabbed to death.  

At Johnson's funeral last week, friends and family remembered him as a quiet, bright and motivated young man. Johnson was in his fourth year of McMaster's engineering program when he was gunned down. 

Brandon Barreira, 19, of Cambridge was arrested and charged with first-degree murder. He was set to appear in court Thursday. Police said they seized evidence relating to the case.
