Sammy killed his gay brother-in-law.

Sammy was also implied to be gay by some because he was a hairdresser and took great care grooming himself, then again, he was one of the only guy's who didn't wear suits every day, preferring instead to wear construction clothing.

Personally, it wouldn't surprise me if Alite and/or Gotti Jr. were bisexual.

There's just something about the tension between them, their sense of grooming and the blatant overcompensating with their macho posturing.
