In New York City, four people were killed and a fifth badly injured early Saturday after a man with a metal bar attacked homeless people as they slept on the sidewalks of Lower Manhattan’s Chinatown. Police arrested 24-year-old Randy Santos and charged him with the murders. Santos is reportedly also homeless and has struggled with addiction. The Coalition for the Homeless warns that in recent years homelessness in New York City has reached the highest levels since the Great Depression of the 1930s.
