Seems very promising now.
per CNN:
A man being questioned in connection with the fatal shooting nearly a week ago of UnitedHealthcare’s CEO in New York City was found Monday in Pennsylvania with a gun with a suppressor like the one used in the homicide, law enforcement officials briefed on the situation tell CNN.
The 26-year-old was picked up at a McDonald’s in Altoona after an employee thought he looked like the man in New York Police Department photos and called police, the sources said. He had fake IDs, including one NYPD believes was used by the killing suspect in New York, they said.
Altoona police responded to the call, picked up the man and searched him, the sources said. The man also had some documents investigators want to examine as potentially relating to motive, though further details on them were not clear.
Altoona police are waiting for NYPD detectives, who are en route.
