Man attacks homeless, disabled bus passenger: 'You owe me for making my grandmother a slave!

A black man reportedly attacked his fellow Maryland Metrobus passenger — a 52-year-old homeless and disabled white man — in late September, spitting in the man's face and blaming him for "making my grandmother a slave."

What happened?

Marquis Evans-Royster, 27, allegedly attacked the man, telling him, "You owe me for making my grandmother a slave."

According to WJLA-TV, the victim initially ignored Evans-Royster's advances. Evans-Royster then began going through the man's pockets, which encouraged bystanders to intervene in the situation.

When approached, Evans-Royster charged at those attempting to defend the man, and began spitting on the victim. Evans-Royster then threatened to throw a cup of urine on the man.

What stopped the attack?

Evans-Royster only stopped his attack when the bus driver warned that he was going to contact police. The suspect allegedly got off the bus without paying.

The driver reported that Evans-Royster referred to all white people as evil and said that two white passengers on the bus should die.

On his way off the bus, Evans-Royster reportedly ripped off one of the bus's side-view mirrors before fleeing the scene.

Police caught him four days later at a local subway station.

Evans-Royster was charged with race/religious harassment, robbery, second-degree assault, destruction of property, possession of a false ID, and theft.

According to records obtained by WJLA, Evans-Royster has an "extensive" criminal record. His next court appearance is scheduled for Oct. 27  in Montgomery County District Court. If convicted, he could face 30 years imprisonment.

When interviewed by WJLA, Desi Cureton, another passenger on the bus, said that Evans-Royster should be subjected to a mental health screening.

"Who carries around a bottle a urine?" Cureton asked. "If I was the judge, I would send him for mental health evaluation."
