Maurice Anthony Newson Jr., 30, has been arrested and charged with two counts of first-degree murder and one count of robbery with a firearm in connection with the March 22 killings of elderly couple Major and Claudette Melvin in their Fort Lauderdale home. Newson, who is the on-and-off boyfriend of one of the Melvins' granddaughters, was previously arrested in May for stealing their red Ford Fusion, which he later sold. The couple was discovered shot dead in their home, and their vehicle was initially missing but later recovered. Investigators are still determining whether any other suspects were involved in the case. Newson's arrest comes after months of investigation following the brutal murders, which shocked the local community. Police continue to seek information regarding the case from the public.
