A 38-year-old man held on Rikers Island died of "acute intoxication due to the combined effects of fentanyl and heroin" in February, the city's Office of the Chief Medical Examiner said Tuesday. His death was accidental, according to the medical examiner.

Tarz Youngblood was being held at the jail facility and was transported to Elmhurst Hospital on Feb. 27, where he died, the Department of Correction said at the time.

A report released Monday by the Board of Correction, a jails oversight body, found correction officers did not conduct proper rounds every 30 minutes as Youngblood died. The cell he was in was not checked for three hours, according to the report.

“DOC staff’s failure to regularly check on the status of every person every thirty minutes (particularly at night) is a chronic and life-threatening issue,” the report read.

Youngblood was the first person in DOC custody to die this year. As of Tuesday, four inmates held on Rikers had died, including 25-year-old Dashawn Carter, who killed himself Saturday, according to the medical examiner. 

“Mr. Youngblood was a father who struggled with homelessness and his death is a tragedy. In our prior representation of him, we found him to be a kind and well-intentioned man. Yet while on Rikers, he was unable to receive necessary medical treatment in a timely manner due to logistical ineptness, resulting in extreme pain and suffering," Taylor Garzone, a forensic social worker with New York County Defender Services, said in a statement when Youngblood's death was first announced in February. "Mr. Youngblood's death is a devastating reminder that Rikers Island is a humanitarian disaster. The conditions there are unconscionable. The only path forward to end the death and misery on Rikers is federal receivership."

On April 26, a federal judge ordered the city and Rikers' federal monitor to come up with a new plan to overhaul the jail within three weeks. Prosecutors previously asked for the jail to be placed under a federal recievership.
