Detectives have charged a man with first-degree manslaughter after his alleged victim was found unconscious and covered in blood.

The Suffolk County Police Department said early Thursday morning that 32-year-old Brentwood resident Samuel White was arrested for allegedly murdering Edwin Rivera, who was found lying on Clinton Avenue in Huntington the previous day.

A 911 caller had reported the body, and officers found the 39-year-old from Bay Shore on the ground next to his 2015 Mercedes. He was pronounced dead at Huntington Hospital.

Police had said Wednesday that the death had been ruled criminal and detectives were waiting on an autopsy from the county medical examiner’s office to determine how he died.

No attorney information was available for the murder suspect, White, on the New York State court system’s online database.

Rivera’s was the second body found in the Huntington area this week. Just a few days earlier, officers had found the body of 33-year-old William Sarcenolima, of Huntington Station, partially in the roadway on West Hills Road. He too was pronounced dead at Huntington Hospital and his body was transported to the medical examiner’s office for an autopsy. Police have not yet announced a cause of death, but said at the time the body was found that Sarcenolima may have been a victim of violence.
