You thought the 12 year old in the parking lot was bad. INTERCESSION CITY -- Five children, including 2- and 5-year-old sisters, were injured Wednesday when an 11-year-old girl took a pickup for a joy ride on the first day of summer vacation, lost control and flipped the vehicle onto its roof, the Florida Highway Patrol said. Driver Yurilia Valdovinos found the keys, which had been hidden because the owner, the boyfriend of Yurilia's sister, said the pickup had brake problems, FHP Trooper Kim Miller said. Accompanied by the other children, the girl took the vehicle from her home in rural Intercession City and drove to a street off Poinciana Boulevard near Poinciana High School. The 1998 Ford F-150 extended cab fishtailed, and she overcorrected, causing the truck to overturn onto the shoulder of Crescent Lakes Way, Miller said. None of the children was wearing a seat belt, and the 2-year-old was not in a car seat, the FHP said. The accident happened about 2:15 p.m., one day after Osceola County public schools let out for the summer. Samantha Lopez, the toddler, broke her leg and was in stable condition Wednesday night at Arnold Palmer Hospital for Children & Women in Orlando, authorities said. Her sister, Alexis Lopez, 5, suffered minor injuries, as did Ruby Clinage, 14, and her sister, Heather, 12, both of Intercession City, and Yurilia. The Clinage girls were sitting in the front seat, Miller said. The four were treated at Osceola Regional Medical Center. The truck belongs to Omar Lopez, the father of Samantha and Alexis. Yurilia is the sister of Lopez's girlfriend and lives with the family, the FHP said. Lopez had hidden the keys because the truck has brake problems and he did not want anyone to drive it, Miller said. The Lopez family could not be reached for comment. Nobody answered the door at their home. Yurilia was ticketed for careless driving, having no drivers license and not putting Samantha in a child seat. Troopers also referred the case to the state Department of Children & Families to see whether intervention is warranted. It is not known whether any adults were home at the time of the accident.
