SPRINGFIELD, Mass. (AP) — A Springfield man has pleaded not guilty to fatally stabbing another man outside a city homeless shelter where they were both staying.

Jose Ramos held without bail at his arraignment Monday in Hampden Superior Court.

Police say Ramos and Luis Sanchez were arguing in the basement of the Worthington Street shelter in March. After they went outside to fight, shelter staff notified police.

According to documents, police arrived to find Ramos clutching a "knife-like object" while Sanchez was bleeding from two stab wounds. Sanchez was taken to the hospital and pronounced dead.

When the detectives approached him, they say Ramos stood up and put both hands behind his back.

Ramos told police Sanchez is "dangerous" and always carries knives.
