Toronto Police are looking for two men wanted in a murder that they say was the result of a robbery gone 
wrong.

On October 2nd, Graham McMillan was working as a security guard at an illegal pot dispensary in the area of Keele Street and Canarctic Drive when four suspects, two armed with a rifle and handgun, showed up. There was a very brief tussle that spilled out into the parking lot and that's where the 44-year-old was shot and killed.

The four didn't end up stealing anything and took off running.

Nineteen-year-old Jahnoye Carpenter and a 16-year-old boy who can't be named have been arrested. Both are facing charges of second-degree murder and arson.

Police are asking for help identifying the remaining two suspects.
