In United Healthcare says the suspect and CEO Brian Thompson's
murder is not a member of the health insurer.
The news comes as prosecutors present new evidence hoping to
secure an indictment against him.
We're also learning new details about the suspects time behind
bars.
ABC News senior investigative correspondent Aaron Katersky has the latest
on all of that.
So Aaron, a lot happening with this investigation, but you're
also learning more about his extradition fight.
Well, he's he's got an extradition hearing scheduled now in
Pennsylvania on December 30th.
So in theory, Diane, he could be back here in
New York by the new year.
Meanwhile, police are closing in on a possible motive.
The young man charged with murdering Brian Thompson was never
a client of United Healthcare.
But this morning, police say they're investigating whether Luigi Mangione
targeted the company because of its size.
The company tells ABC News Brian Thompson's killer was not
a member of United Healthcare.
The NYPD telling NBC New York.
Mangione did, however, mention it's the 5th largest corporation in
America.
We anticipate that it before very long, he'll be brought
back to New York where he needs to be facing
the consequence of that horrific, audacious attack on the streets
of New York City.
Police sources tell ABC News at least three search warrants
have been issued for the alleged shooter's phone, backpack and
the Manhattan hostel where he stayed.
And sources tell us prosecutors have started presenting evidence to
a grand jury seeking an indictment that could strengthen their
case from Mangione's extradition from Pennsylvania.
A judge said a hearing for December 30th.
For now, Mangione's locked in a cell nearly identical to
this one.
His supporters are donating 10s of thousands, thousands of dollars
to online legal defense funds, including one set up anonymously
on Give Send Go, the group saying We are not
here to celebrate violence, but we do believe in the
constitutional right to fair legal representation.
In Seattle, this chilling message appeared briefly on a road
sign threatening other CEO's, the city blaming a private construction
contractor and a Florida woman charged with threatening her insurance
company after it denied her claim in a phone call.
Brianna Boston allegedly said, delayed, denied.
I suppose you people are next, echoing the words police
say were written on the shooter's bullets.
And that woman later told police that she posed no
danger to anyone and did not own a gun.
But Diane, it really goes to show how this entire
case has touched a nerve across the country and and
revealed a deep discontent, even anger with the whole health
insurance industry.
Also learning more about the suspects movements after the shooting.
What's the latest on that?
They're trying to piece all of this together so they
can get an airtight prosecution by the time he does
come back here to New York.
So at first, remember it was thought he took a
taxi cab up to the George Washington Bridge bus terminal,
but he may have found there, there wasn't a suitable
bus to take.
So now investigators are thinking that from there, he may
have gone down to Penn Station and actually taking a
train out of New York, perhaps to Philadelphia and, and
Philadelphia authorities have said he was crisscrossing Pennsylvania from Philadelphia
to Pittsburgh and back again.
And they're trying to piece together his movements in that
state over several days.
A lot to put together here.
Aaron Katersky, thank you.
