Matias Munoz said that when he came downstairs Sunday morning, he saw the carpet and floor were charred, and that there were blackened fire-starter bricks strewn across the lobby.

The building manager showed him surveillance video, which he said appears to show two men light a package of the bricks in the lobby and secure the front door handles together before leaving through the side door around 5 a.m. Sunday.

“On top of all that, somebody trying to do something as insidious as taping the door shut so people can’t leave if there’s a fire in the main lobby — it’s terror, is what it is,” Munoz said.
