Landscapers discovered the body of a female near Osceola-Polk Line Road on Friday. The uncle of the girl told Local 6 on Saturday the body discovered is that of Alexandria.

According to detectives, Saint Simon borrowed a car from his uncle, Charles Pierre St. Simon, and may have been driving around with Alexandria the day she disappeared.

Saint Simon initially lied to detectives about lending the car to his nephew, according to the arrest affidavit.

It states Saint Simon admitted that his nephew spoke to him on the phone and asked him not to tell law enforcement that he was in possession of the car on July 27-28.

Investigators found the car in Pine Hills, processed it for evidence and returned it to Saint Simon.

Local 6 tried speaking with him at his Orlando home, but he did not want to answer our questions.
