interview of him was sufficient and that further dna testing would prove that. i can remember saying, well, his dna isn't there, there's no case. >> in fact, despite the long interrogation, dna would eventually link the murder of the depalmas not to alex but to a troubled ex-marine named robert jardin, a stereo, vacuum cleaner and set of keys stolen from the couple would also be found in jardin's possession. >> he did say when asked that bostick was not involved in the murder. >> this is reinforced by phone records that show alex in tampa about 35 miles from the depalma home at the time of the crime.
