According to the New York Post, the victim's younger brother Wilmer said Winston had been dating Betances's little sister — but that she had ended it just hours before he was killed.

"I'm pretty sure this all had to do with a breakup that he had been dealing with yesterday," he said. "This is [his ex-girlfriend's] older brother we're talking about."

The 17-year-old said he didn't remember exactly why she'd broken up with Winston, but it had "something about him being too overprotective," adding: "But I don't know what that means."

His brother had been "very emotionally distraught" over the break-up, he said.
