Breaking News : Mangione’s lawyer, Thomas Dickey, says there is no evidence linking his client to the shooting of UnitedHealthcare CEO Brian Thompson, per ABC…

We’re looking forward to beginning our inquiry as to what evidence may or may not be out there,” Thomas Dickey said .

Luigi Mangione’s lawyer has said that he’s “not aware of any evidence” that links the 26-year-old suspected killer to the murder of UnitedHealthcare CEO Brian Thompson.

Appearing on Good Morning America on Wednesday, Dec. 11, Mangione’s defense attorney Thomas Dickey was asked by host George Stephanopoulos if he stands by his statement that he’s seen “zero evidence tying Mangione to the murder.”

That is correct,’ Dickey responded. “We had a brief hearing yesterday, but there is one document – an arrest warrant from the state of New York – which merely referenced a statute. We’ve seen no evidence. That’s one of the many reasons why we’re challenging the extradition at this point so we can see some evidence and get a little more detailed information about the charges against Luigi.”

PEOPLE previously reported that a lawyer for Mangione told a judge on Dec. 10 that he will contest a pending extradition to New York to face the murder charge against him. The Blair County Courthouse confirmed to PEOPLE that Mangione was denied bail on Tuesday by Judge David Consiglio and will remain in custody in Pennsylvania as he fights attempts by New York prosecutors to bring him to Manhattan so he can face a second-degree murder charge.

Stephanopoulos, 63, then asked Dickey about the ghost gun that was found on Mangione when he was arrested on Dec. 9 and the alleged “written admissions” of murder.

“As I indicated yesterday, I have not been made aware of any evidence that links the gun that was found on his person to the crime. These are things we’re looking to see. Yesterday was fast, today’s another day. We’re looking forward to beginning our inquiry as to what evidence may or may not be out there.”

The gun looks exactly the same as the one that was used,” Stephanopoulos then noted, to which Dickey replied, “A lot of guns look the same.”

“If you brought a gun in and said, ‘Well, it looks like that.’ I don’t even know if it would be admissible,” he continued. “And if so I would argue that it wouldn’t be given much weight. That’s why they do ballistic tests, ballistics, examination, a test of all that to try to match that. Trust me, they’re going to try to match that firearm to the incident by more than just, ‘Well, it looks like that.’ ”
