The 22-year veteran of the force was shot and killed last Monday at a GTA Tim Hortons, in what police have called an "unprovoked" incident. One other person in the area was also shot and received life-altering injuries.

Following this atrocious event, the alleged suspect went on to shoot three more people, resulting in the death of two, before he died following an "interaction" with Hamilton Police.

Motive for this horrendous shooting spree has yet to be determined, but police say Hong was targeted for being in his uniform.
