Hamilton police have made four more arrests in connection with the Nov. 30, 2013 shooting death of McMaster University student Tyler Johnson.

The 30-year-old Hamilton man was gunned down during an early-morning altercation in front of Vida La Pita, a restaurant on King Street West at Caroline, just west of Hess Village.

On Dec. 11, officer arrested a 19-year-old man in Cambridge and charged him with first-degree murder in the killing.

At the time, police said they were looking for more suspects in the case and released surveillance footage that captured individuals believed to have been involved in the shooting. 

The probe then led investigators to seek warrants for the arrests of four more suspects in the case. On Friday, police took two Hamilton men — a 34-year-old and a 25-year-old — into custody and charged them first-degree murder.

In addition, two women, aged 27 and 28, face charges of accessory after the fact.

All four accused were set to appear in court on Saturday.

Police ask anyone with addition information on Johnson’s death to call Det. Dave Oleniuk of the Hamilton Police Service’s homicide unit at 905-546-3874 or Crime Stoppers at 1-800-222-8477.
