Luigi Mangione, 26, “was a casual guy, nice, quiet — he said ‘good morning’ with a smile,” said the driver, who didn’t want their name used.

Mangione was not wearing a mask, according to the driver, who recognized him Monday from a picture.

After the shooting, Mangione traveled by bus from New York City to Philadelphia, then went to Pittsburgh, according to officials at a news conference Monday evening in Hollidaysburg, after he’d been arraigned on local charges related to his apprehension Monday morning at the McDonald’s on Plank Road.

That happened after a customer recognized Mangione and alerted an employee, who called 911.

Mangione was charged with second-degree homicide by New York City police late Monday.

Since the arrest, police have reportedly been trying to track his movements in the Altoona area.

Mangione tried to book a room at the Horseshoe Curve Lodge on Pleasant Valley Boulevard, across from the Van Zandt VA Medical Center, about 9 a.m. Monday, according to an interview with a motel employee that was aired Wednesday by ABC News.

A desk clerk at the motel confirmed that to the Mirror, but added that he couldn’t say more.

Mangione walked across the motel lot, entered the lobby and was told there were no rooms available — after which he walked south along the boulevard, in the direction of McDonald’s, said Logan Township Police Chief Dave Hoover.

The 911 call from McDonald’s came at 9:14 a.m., officials at Monday’s news conference said.

Amtran CEO Josh Baker has been reviewing surveillance videos to determine whether Mangione rode a bus from the Transportation Center downtown to the Plank Road area, where the McDonald’s is located, and which is three miles away.

When he learned of Mangione’s arrest, Baker was confident that Mangione had taken the bus.

He’s no longer confident, as the drivers on the two routes that service the McDonald’s area have told Amtran management they didn’t see Mangione, and no one else has come forward to say he was a rider, Baker said.

He’s checking video for those routes for Monday morning, to be sure.

There is no bus service on Sundays.

Baker’s effort involves watching four or five hours of video for three or four vehicles, he said.

There are a total of 10 cameras on each bus, some inside and some out.

Baker was focusing on footage from the interior camera that is trained on the front door, he said.

If necessary, he can supplement that with footage from other cameras, he said.

As an alternative to riding the bus, Mangione could have walked across town, or taken an Uber, which would have required using a cellphone, Baker said.

There is currently no cab service in Altoona.

The Mirror checked with employees at seven other establishments, near the Transportation Center or on the way to the Plank Road McDonald’s, asking whether anyone had seen Mangione.

An employee at one establishment had no comment, while those at all the others said they weren’t aware that Mangione had come in.
