You're looking at investigators
taking boxes
of what appears to be evidence
from the suspected Gilgo Beach
serial killer's home.
Now, this happened just moments ago.
What you're looking at on your screen.
Investigators have been zeroing in
on the suspect's
home, trying to determine
if someone or something is buried there.
We're also learning
the search inside his home
includes a vault
where they found more than 200 guns
and that that search
was, quote, fruitful.
Human is a well-established
New York architect
and is charged with killing
at least three women
who vanished more than a decade ago.
Jean Casarez is OUTFRONT
tonight from the suspect's home
Police confirming that they have been
using ground penetrating radar technology
and a backhoe to dig outside
the home of serial
killing suspect Rex Schuerman
to see if they can find anything,
a forensic value
underneath that ground,
perhaps more evidence of human remains.
It is a different type of technology
where it will help us
be able to identify anything in that
backyard that we need to
take into our possession.
Authorities not ruling out today
that human might be linked
to more victims than the three murders
he is currently charged with.
It's hard to say.
Once again, is this person
who's been at large
for a long period of time?
We'll see if there's any other victims
over on Ocean Parkway or anywhere else
throughout the south about Long Island.
Police will continue searching the home
for at least one
or two more days, the police commissioner
told reporters.
And investigators
also note the importance
of searching through the garage.
An addict as well
A law enforcement source
confirmed to CNN.
I hope that they don't find something.
But at the same token,
I feel like
it's just going to be more evidence
on top evidence that this guy,
Bonnie Buford, said
Human has been to a local grocery store
she works at in the past.
That's what made me get intrigued
with the whole storyline
because I'm like not really seen so.
But I didn't suspect
that he was doing that.
But he looked like
he could be up to something.
Investigators not ruling out
other suspects in the killings.
I think that this investigation
is going to last
as long as it takes to make sure
that every piece of evidence
that's gathered,
every suspect or if it's just a human
will be excluded or precluded from
this investigation
or possibly being a suspect.
The investigation
spanning beyond New York
to three other states,
something
the sheriff says was unexpected.
The sheriff
also noting that human has been stoic
during his interaction years in jail.
If you think about someone
that two weeks ago
was walking around freely,
he seemed very comfortable
inside of the cell
And we do have some activity
going on right now behind me.
You can see
all the official
vehicles are out in front.
There are law enforcement
positioned on all sides.
Some right over here,
right behind those vehicles.
That's the home.
I want to show
you more of that video
of what we shot just minutes ago
because they were bringing
these boxes out
and they look like packing
boxes, moving boxes.
They appeared to be sealed.
They were stacking them on the table
and then they were putting them
in like a moving van.
Also, there was another vehicle
and they shut that down.
But it looks like
they're closing up for tonight.
But they are taking a lot of items
from that home Erin.
All right, Jeanne, thank you very much.
And as we see that evidence coming out,
let's bring in Dr.
Lawrence Kobilinsky.
He's a forensic scientist
and expert in DNA analysis.
Also a professor at the John
Jay College of Criminal Justice
in Manhattan.
And Dr.,
it's always great to speak with you.
Look,
you and I have spoken over the years.
You have investigated crimes
for more than 40 years.
You've consulted on high profile
cases, Casey Anthony's murder
trial, the murder of JonBenet Ramsey,
What stands out about this case to you?
Well, I'm not surprised at all
that bodies were discarded at
Gilgo Beach.
I've been there.
It's a very difficult area.
For K-9 units or police investigators
to go through there.
It's not walk.
People don't walk around there.
It's rather desolate.
That doesn't surprise me.
What surprises me
is that so many years have elapsed
with so little progress.
People are fearful that,
you know,
there's a serial killer in their midst.
What are we going to do
when the police aren't doing anything?
I think that's what stands out
in my mind.
So now that
and obviously there were mistakes,
as we point out,
then they reinvent
reinvigorated the investigation.
We don't know what we don't know.
We now know it's in three states
that they're looking.
We know that there are additional
bodies have been found on Gilgo Beach.
We don't know if he's involved.
We don't know if there are many,
many more.
I mean, do you.
Do you think that it's possible
that they are able to tie human
at this point to many more murders?
I think it's very possible
because human's DNA profile
is now on CODIS.
This national database
and this database has subdivision
and it's got unsolved cases
and it's got felons.
Human is on that list.
If there is some kind of match,
the algorithms of the quota system
will find it and link him.
And so you can come up
with that information.
Also, there are other bodies there at
Gilgo Beach.
They're around in that area.
And they have to be connected
to somebody.
It may not be human, but it's possible.
It is.
So we have to wait and see
what time tells us.
And Dr.
Kobilinsky, on this front, obviously,
we don't know what he's been doing
if we don't know how many victims there
possibly could have been. Right.
So I don't want to imply
that every victim is a decade
or more ago.
It is the reality that the once
he is being charged with right now
are a decade old.
So is there any issue in
terms of DNA degrading
when you say his DNA is now in the system
and you can cross-reference
it with everything?
Is that is that good?
Is the quality of the DNA high enough?
If you're looking at murders in the past?
Well, if you're looking at old specimens,
it may not be, as it turns out.
Look at the example of a hair.
A hair has a root and a shaft.
The root has good cellular material.
And you can do
the normal autosomal molester
DNA analysis
and get a lot of data,
very identify data.
But on the other hand,
the shaft of the hair
doesn't have that same situation.
It's got mitochondrial DNA,
which is present
thousands of times
in greater amounts than nuclear DNA.
So when when
biological specimens decompose,
the only thing you've got left
is mitochondrial DNA.
You find it in hair
you find it bone, you find it in teeth.
And so if it's old evidence,
you can do mitochondrial DNA analysis.
Dr. Kobilinsky, thank you.
