Douglas Smith Killed In Gym Fight Over Exercise Equipment

An altercation over an exercise machine turned deadly in an East Flatbush gym Saturday.

Douglas Smith was jumped by two thugs wielding a knife and hammer after an argument over who claimed "first dibs" on a Nautilus machine. The 50-year-old social worker quarreled with another gym member, who in turn called the alleged killers.

The New York Daily News reports:

Witnesses said Smith was exercising on the elliptical machine when the duo ambushed him from behind, stabbing him three times in the back and walloping him in the head with a hammer.

One of the alleged killers, Shawn Hing, was arrested Sunday night and charged with second-degree murder. The other alleged killer and the gym member are still at large.
