Seconds later, 23-year-old Luis walks in and heads up to his second-floor apartment. The suspect, seen wearing sunglasses and carrying a backpack, follows the victim up the stairs, but then continues up to the third floor, where video shows him removing a gun from his bag. He then heads back down and threatens Luis at his front door.

Luis said he was terrified and that he prayed as he tried to fight off the armed robber, but the suspect put him in a chokehold, causing Luis to pass out on the stairs. The suspect is then seen grabbing the victim’s phone, backpack, and wallet, which was holding $1,000 in cash.

Neighbors told CBS2’s Sanchez they are worried for their own safety now.

“I was panicked because I live within a few feet from where it happened. Even other people who are in the building had never heard of such a thing happening in this neighborhood,” Brittany Porter said.

The robber was wearing a white t-shirt with the words “R.I.P. Youth” on its front and a graphic of a tombstone with an upside down house on the back. He was also wearing grey sweatpants and black sneakers.
