A 21-year-old college student has been charged with first-degree murder after Florida authorities say he drove to his mother’s home and stabbed her multiple times Saturday because “she got on my nerves.”

Authorities are investigating at a central Florida jail after an inmate believed to be on drugs violently fought deputies and died after being restrained.

Suspects are Tony “TJ” Wiggins, 26, Mary Whittemore, 27, the girlfriend of TJ, and William” “Robert” Wiggins, 21, the brother of TJ, all of Frostproof. At the direction of TJ, Robert was told to make a U-turn and follow them, according to police. They went back to their trailer to eat, Robert told detectives. Judd said that Robert told TJ what he had heard. TJ Wiggins was also seen in that video with her.
