greenwood and they knew it was david paul frediani, but they couldn t prove it. eventually helena greenwood s murder was relegated to san diego s cold case files and forgotten. over the next several years, helena s parents died, her husband, roger, developed cancer and he, too, passed away. and who is there to mourn for helena? very few and growing fewer. and gen-probe went about the work helena had been pursuing before her death, looking for ways to use new dna technology for quicker, faster medical diagnoses. david frediani served only three years of his five-year sentence and was released. he returned to his accounting practice. this is a very egotistical, self-centered, obviously
sociopathic person. hey, i just got away with murder, you know. his life went on and he prospered. and that s where the case stood for another ten years. until investigators in san diego s cold case unit decided to take a second look at helena greenwood s murder. and deep in helena s file was a piece of information that immediately caught investigators attention. seven days before helena s murder, david paul frediani was involved in a minor traffic accident in southern california not far from helena s home. the defendant had no business being in southern california. we knew he knew she lived down here. although we didn t know how he had that information. but it just seemed a little bit strange that he s awaiting trial, he lives in san francisco and he takes a trip down to southern california.
