A homeless man charged in the beating deaths of four men as they slept on the New York City streets may pursue a mental health-related defense, his lawyer told a judge Monday at his arraignment. Randy Santos, 24, pleaded not guilty to murder and other charges during a brief excursion to court from the psychiatric ward, where he has been held since shortly after his arrest in the Oct. 5 killings in Manhattan’s Chinatown neighborhood. Santos appeared in an orange jail suit and gray undershirt with his hands cuffed behind his back and a Spanish interpreter by his side.
