0:00.0	Additional items and evidence from Kathy's case were submitted to the Arizona DPS Crime Lab for updated DNA testing in late 2017.
0:08.3	These were the bike helmet, swabs from both rocks, a swab from the ratchet wrench, and Kathy's fingernail clippings.
0:16.3	The lab's report dated January 25th, 2018, says they weren't able to make any more headway on the helmet or the ratchet, on which a partial male DNA profile had been found a few years earlier.
0:28.0	Basically, insufficient DNA remained on these items for the state crime lab to extract.
0:32.9	The same was true for the rocks.
0:35.2	From the fingernails, the lab was able to obtain a very small amount
0:38.5	of Y DNA in the form of a mixture with Kathy's DNA. Again, this partial male profile was a mixture
0:45.1	and was not conducive to entry into CODIS. However, there were sufficient markers for entry into
0:50.4	the Arizona's state DNA database referred to as SDIIS. No hits were generated there.
0:57.0	And everyone the investigators tested against the fingernail Y DNA profile going forward failed to match.
1:03.9	What this meant was that even in the late 2010s, the Kathy Sposito homicide was not in the DNA Database known as CODIS due to insufficient DNA.

1:35.3	He was arrested in May 1982 at age 25 for attempting to sexually assault a woman he abducted at knife point from a midtown Tucson neighborhood.
1:44.7	He forced her into a car, drove to a remote area, and sexually assaulted her by demanding
1:50.0	her to perform Felacio. He then slashed her with a knife and pushed her out of the car after
1:55.1	she bit him, according to the Tucson citizen. The survivor got the license plate number and
1:59.9	gum was arrested and sentenced to prison.
2:02.6	He was released in September of 1986. In 1981, he sexually assaulted two girls on the Granite
