A suspect was just arrested in Pennsylvania over the murder of UnitedHealthcare CEO Brian Thompson. He was trying to use a fake ID at a McDonalds when someone called in a tip to local law enforcement.

According to the New York Post, the man had a manifesto on him as well as a gun and silencer:

A person of interest was nabbed Monday in the fatal shooting of UnitedHealthcare CEO Brian Thompson — busted possibly trying to use a fake ID in a McDonald’s, law enforcement sources said.

The man — who sources said is being eyed for the coldblooded, targeted execution in front of a Manhattan hotel last week — allegedly had a manifesto on him when he was taken into custody by cops in Altoona, Pa.

He also had a gun, silencer, four fake IDs and other items “consistent” with what authorities were looking for in the case, sources said.

Law enforcement was still trying to figure out the man’s real identity, sources said.

He was nabbed on a tip called in to local cops, who apprehended him, sources said.

The NYPD was on its way to Altoona late Monday morning, sources said.

This is fantastic news, considering. I hope they throw the book at him.
