No.

Altoona police responded to the 911 call placed by the McDonald’s manager, who said multiple customers told her a person in the back corner looked like the man wanted by New York authorities for assassinating UnitedHealthcare CEO Brian Thompson.

“They’re just really upset, and they’re, like, coming to me. And I was like, well, I can’t approach him, you know?,” the manager said.

During the 911 call, the dispatcher tried to get a description. The manager told her that because of how the man was dressed, it was hard to get a good look.

“Well, he has a beanie pulled down, so the only thing you can see is his eyebrows,” the manager told 911.

His bus stopped at a McDonald's and multiple "random" customers kept trying to get an employee to call, getting upset with them when they wouldn't but refusing to call themselves.

Even tho you couldn't see what he looked like.

That smells exactly like they knew he was on the bus, and needed a civilian to call in a tip to justify the huge response that magically showed up in the middle of nowhere in minutes.

The most likely explanation is all those super concerned citizens who didn't want the reward they were trying to get minimum wage workers to take were cops/feds.
