“They rushed him to the ambulance. There was no movement in the body; no life. They were pushing down on the body; he was very still,” the neighbor said. “And the grandmother said she didn’t know it was such a serious thing; she knew he was throwing up all day; he was sick, but he had no fever.”

On Tuesday, the New York City Medical Examiner’s office ruled that Poseidon’s death was caused by blunt trauma to the torso with abdominal injuries, and the manner of death was a homicide.

There had been no arrests as of late Wednesday.
