Why did Lisa Michelle Rosa refuse a sobriety test? Why did the sheriff Department not arrested for refusing it? Why was she allowed to keep her driver license? She hit James at a high rate of speed!! Why is the Sherriff department refusing to release any information to the press or the family? Why did she file a claim with her insurance company to get her truck fixed less than twelve hours after she killed a seventeen year old boy? Why was she fired from the sheriff department? Is this a case of the Polk County Sheriff’s Department covering for one of their own!!!!
