Fired Worker Kills Foreman, Self

Manhattan luxury condos sell for millions. However, few wealthy residents think about the construction workers who build them. Those living at Waterline Square in Manhattan are no exception to this rule, especially considering a deadly murder-suicide took place there during its construction back in 2017. So, what happened? Carpenter Samuel Perry had just gotten fired for insubordination. Instead of finding a new job, he decided to murder his boss.

Two days after being fired, Perry entered the job site early in the morning. He found his supervisor, Christopher Sayers, working on the 38th floor. Perry shot him in the head and walked away. He encountered several coworkers on his way out. The murderer made jokes and laughed as if nothing had happened. However, Perry shot himself in the head when he reached the 5th floor. The murder-suicide did nothing to stop progress on the Waterline Square, though. You can still buy a condo there if you happen to have a few extra million lying around.[3]

The two Missouri men had taken a job in Wisconsin back in 2018. From all accounts, they were talking as usual. But when Flores began teasing Navarro, it went south. So far south that Navarro took a circular saw and slashed his colleague’s throat.

One witness claimed there was no visible argument between the two men. Flores handed Navarro the saw himself. But instead of cutting shingles, Navarro reached forward and began cutting Flores in the face and neck. Flores fell backward onto the garage roof, where he died of his injuries. Navarro later claimed he had been drugged, but no proof was found. In fact, no good motive was ever discovered for the gruesome crime.
