The attacker was spotted carrying shirts as he walked into the 303 Laundromat at 2:42 a.m. Thursday in the Claremont section.
Once inside he stabbed two men and ran off southbound on College Avenue.
A 47-year-old man was stabbed in the back. He was taken to Lincoln Hospital in stable condition.
Another man was stabbed in the legs, torso, and back. He was pronounced dead at Lincoln Hospital.
The 47-year-old victim told police he is homeless and was sleeping inside the laundromat with his friend when the stabbing occurred, sources say.
Police found two meat cleavers on the stoop outside the laundromat hours after the attack.
The incident reinforced concerns neighbors already had.
"Me as a female, I don't feel safe washing my kids' clothes, washing my clothes and me coming at night. There's a bunch of people that do drugs, sleeping, bent over. Nobody wants to see those things. Right inside, on the corner, everywhere," a laundromat customer said.
It is unclear if the suspect knew the victims.
Patricia Santori said she knew the victim as 'Flaco,' a homeless man she said cleaned and watched over the all-night laundromat in return for a roof over his head.
"He's not a bad person, he used to help everybody out and in return, you get killed? Santori said.
Police said surveillance images show the victim and a friend who was also sleeping at the laundromat being stabbed.
"We were all his family basically. You know when you're out here and you know each other you're on the street. I've been here for 10 years. We call each other family, you know? Santori said.
Police do not know a motive for the attack or a suspect.
The suspect is described as in his 30s, 5'8" tall, 140 pounds, and wearing a green and black shirt, black pants, and a black and white hat.
