Ruben Whitworth, 16, was booked and charged Thursday with second-degree murder with a weapon for the Aug. 25 killing of Jordan Dowdy, who was found fatally stabbed that Monday afternoon at a residence in the 5400 block of Northeast Third Avenue in Oakland Park, according to local police.

Dowdy’s mother told FOX and ABC affiliate WSVN that her son allegedly had problems with Whitworth in the past, which led to Dowdy being threatened, she said.

“Jordan asked him one day, ‘Ruben, would you like some mozzarella sticks?’ and he told [my son], ‘No, shut the ‘F’ up, or I’m going to stab you and kill you,’” Tiffany Simpson alleged to WSVN about Dowdy and Whitworth.

“Two weeks later, he ended up dead,” Simpson said.

An adult supervisor at the One Hope United foster home was there at the time and found the two teens fighting before the stabbing unfolded in front of her, cops say.

“I need paramedics immediately,” the supervisor said, according to WSVN. “Where was he stabbed?” a dispatcher asked.
