Professional boxer Gervonta “Tank” Davis has been arrested in South Florida on a misdemeanor domestic violence charge.

As detectives in Jacksonville Beach ask for help solving the string of shootings on St. Patrick’s Day evening, leaders and residents are wondering how to prevent violence like this from happening in the future. Police released frantic videos of people scattering after one of the shootings just before 8 on Sunday. A 21-year-old man died, and three more men were hospitalized with gunshot wounds. Detectives believe two of the injured were shooting at each other. News4JAX looked at how Miami Beach handled violence last year and a strategy they say has been successful in preventing crime this year.
