In 2001, an unknown male DNA profile was developed by the CBI lab from the cutting of the rug fibers, the ones that had the crusty stain on them.

The profile was entered into the FBI's combined DNA index system or CODIS.

It remained unidentified. Sylvia's Killers profile matched no one in the database. In February of 2012,

the CBI conducted new updated testing on about 14 items from the crime scene. It conclusively

confirmed the results from the less sophisticated circa 1993 testing. The DNA on the towel over

Sylvia's face, the cutting from the sheet the

body was wrapped in, and the rug swatch all came from the same male. This was the same male

whose DNA was found in the vaginal swabs taken at autopsy, showing the presence of sperm.

Then in April of 2012, a consistent YSTR profile was developed from the cutting from the sheet

and the swab of saliva from Sylvia's breast.

Whoever this guy was, he had stabbed Sylvia in the back,

and then thrust her shirt over her head and licked her breast as he sexually assaulted her,

and she lay dying.

They knew a lot about this guy, but they didn't know his name.

In late 2019, United Data Connect, a Denver-based DNA analysis company who had done the

forensic genealogy work on the Helene Prasinski case, contacted the Cherry Hills Village

Police Department, and proposed using the same methods on the quene Prasinski case, contacted the Cherry Hills Village Police Department, and proposed

using the same methods on the quail case. They started the process in January of 2020. UDCs sequenced

two samples from the crime scene and created SNIP profiles of the male DNA contributor. They then

loaded the profiles into both GEDmatch and family tree

DNA and located a relative of the suspect who shared 560 cent to Morgans with him. This woman

was likely a first cousin once removed. It was a complicated family with a large number of members.
