Mangione was taken into custody Monday morning in Pennsylvania to be questioned in connection with the murder of Thompson. 

He was taken into custody at a McDonald’s in Altoona, Penn., which is about 300 miles outside of New York City, after police got a tip that he’d been spotted. 

He was found with a gun, a silencer, fake IDs and writings apparently critical of the health insurance industry, law enforcement officials told the Associated Press.

Police confirmed in a news conference Monday afternoon that Mangione was being questioned in the ambush killing on Dec. 4 of Thompson, who was stalked, shot and killed outside of a Hilton hotel in Midtown Manhattan.

A source tells the Associated Press that the man owns a gun that matches the weapon authorities believe was used in the shooting. Other reports indicate the man was carrying a silencer – which is believed to have been used in the shooting – along with a fake ID and manifesto.

Over the weekend, police released a new batch of photos showing the masked gunman riding in a cab.

The award for information leading to an arrest has also risen to $50,000.

On Friday, police reportedly found a distinctive backpack that the gunman was wearing. Inside, they found a jacket and Monopoly money. According to reports, investigators were also testing a discarded water bottle and protein bar wrapper for DNA.

On the morning of the shooting, police say the gunman is spotted on surveillance video outside the hotel, seemingly waiting for Thompson for about five minutes.

• The suspect stayed at a hostel, checking in using a fake New Jersey ID.
• Police were able to pull surveillance videos of the suspects making a purchase at a Starbucks near the hostels. They had also tracked him on the Subway and visiting other establishments before the shooting.
