SUNSET PARK - The family of a man killed in Park Slope early Sunday morning is outraged that up to 20 people were allegedly involved, police said.

Alex Santiago, 22, was killed by a group of men he and his friends - who were also attacked - apparently did not know. No one has come forward with any information.

The family tells News 12 Brooklyn that another man that was attacked is still in the hospital in a coma.

Police have not yet made any arrests in the case.
