A family of four found shot to death along an isolated stretch of highway had moved to Florida from Texas four months ago, authorities said Saturday according to The Associated Press. . The family, including two boys ages 3 and 4, was found Friday, fatally shot along Florida's Turnpike in Port St. Lucie, Florida, about 100 miles (160 kilometers) north of Miami. Investigators believe their vehicle, a 1998 four-door Jeep Cherokee, had pulled to the side of Florida's Turnpike before someone else in the vehicle shot them and drove away sometime between 1:30 a.m. and 3 a.m. No one has been arrested, but authorities were searching for clues Saturday into the deaths, Sheriff Ken Mascara said.
