Police tracked down Lora, of Washington Heights, in the Bronx on Monday morning. He was taken into custody without incident.

Investigators also discovered a straight razor lying on the sidewalk near a pool of Hernandez's blood. It was not clear if the razor was involved in the crime.

The two men, both of whom had several arrests for assault, began feuding after Hernandez accused Lora of trying to hit him with his car last month, police sources said. It wasn't known what specifically spurred their final confrontation.

Waldy Fernandez, a barber at another Washington Heights shop that briefly employed Hernandez, said the two men had recently been seen arguing in public. "He wasn't a bad guy. Just very aggressive," Fernandez said of the victim. "He was getting in a lot of fights sometimes. I wasn't surprised to hear he had died. But no one deserves to die that way."

Patrons of Hernandez remembered him fondly.

"He was a very hardworking, young man," said Ana Leo, 40, who said Hernandez used to cut her teenage son's hair.
