Video showed the moment the suspect shot the other man, and police later said he was found dead with gunshot wounds to the head.Mayors Eric Adams of New York and Muriel Bowser of Washington called the suspect a “cold-blooded killer” and the shootings “heartbreaking and tragic.”Advocates for people experiencing homelessness said the killings are a grim reminder of the vulnerability and stigmatization facing the homeless population on a daily basis.In New York City, nearly 50,000 people experiencing homelessness were in shelters in December, according to New York’s Coalition for the Homeless. Last year, there were about 5,000 people experiencing homelessness in Washington, according to the nonprofit Community Partnership.Addressing homelessness has become a focal point of public safety efforts in New York City after a number of targeted attacks against women of Asian descent. However, advocates say people experiencing homelessness are far more likely to be the victims of crimes than perpetrate crimes themselves.Contributing: Grace Hauck
