Combined DNA Index System

In late 2025, detectives received a tip, and it pointed them to a 1996 sexual assault report.

The DNA from that case went into CODIS, and it matched another unsolved Houston sexual assault.

And DNA recovered from Cheryl Henry's autopsy.

The man whom they matched to the DNA was 64-year-old Floyd William Parrott.

When the forensic team tried to analyze the DNA for identification, they ran into limitations.

They couldn't extract a full DNA profile and thus weren't able to use the CODIS database to search for matches.

Instead of being discouraged, Young took a more manual approach.

His first thought was to re-examine the prime suspect from decades earlier.

Advanced testing had lifted a genetic profile that investigators in the 1990s could never have obtained with the forensic science of the time.

The DNA belonged to two individuals.

One was Angie herself, and the other was an unknown male profile now identified through the National CODIS database.

The match pointed to a man who was, thankfully, already behind bars.

arthritis that she was so vulnerable and she was taken advantage of by a 22 year old very bad person who got away with it for decades but thank you for sticking with it and even though you no longer worked in that jurisdiction even though you were in getting ready to retire, you kept pushing and they, they were able to submit evidence for DNA analysis and, and check it with CODIS and CODIS eventually came back with a hit when this slime bag was arrested again, um, after having been arrested a number of times earlier.

So what was his name again?

Yeah.

They also ran it through CODIS.

No match.

Even so, they still couldn't rule out Sandy.

One big change, though.

was that CODIS had been formed since the murder.

It's the combined DNA index system and that's exactly what it is.

It's a system that combines all the DNA samples of all the criminals so they can track them nationwide and see if their DNA links to any other cases.

Well during the time that Special Agent Costas took over the case, he wanted to submit that semen sample into CODIS.

Now they knew There wasn't a guarantee that the killer's DNA would be in their system because for that to have happened, he would have had to commit another violent crime and then been caught since 1991 when Jessica's murder had occurred.

But many times when someone commits one crime like this, they're bound to be a repeat offender.

I love science.

Now, we're hearing that some of these results have come back already.

And I heard on a Nancy Grace video, she was saying something like none of the matches even hit in CODIS.

Now, that's simply rumor and speculation by Nancy Grace, but it is pretty concerning.

And you would think that if they had a match in CODIS already, that they would have somebody who would be their suspect.

Now, remember, they said that this killer was messy.

He was sloppy or they were sloppy and that a lot of DNA was found at the scene.

Now, the question is, was any of that DNA belonging to the killer? Because the longer we go here and the more we move away from this being a targeted attack, we have to start thinking, was this some sort of sophisticated plan that was put into place by somebody who had no desire to get caught here? And as we get more information back, obviously, DNA, test results, toxicology, all of that, it'll provide a more robust picture.

But if Nancy Grace is right, and none of this stuff is hitting CODIS yet, that is a bit concerning.

DNA profiles from potential suspects are run through a federal database collected by law enforcement agencies around the country of people arrested for or convicted of crimes.

Profiles collected from unidentified suspects in unsolved crimes are also in the database, known as CODIS.

A match can lead authorities to a suspect who they must then locate and confirm a match with, a process that can take days or weeks.

So when you're dealing with CODIS, there's certainly a lot of information that has to be run.

But remember, they're talking about generally speaking, meaning under normal circumstances.

This is anything but normal circumstances.

And with all of the resources thrown at this case, my guess is that the DNA went to the front of the line.

If there is no hit in CODIS, then investigators can use other methods to find a DNA match.
