A Bronx father was sentenced Tuesday to three to nine years in prison after pleading guilty to suffocating his 8-month-old son with blankets.

Last month, Claude Tinnin, 21, took a plea deal and copped to one count of second-degree manslaughter in Manhattan Supreme Court for the tragic death of little August Tinnin inside the Rutgers Houses on the Lower East Side.

On March 22, 2018, Tinnin smoked marijuana then wrapped his infant son in numerous blankets and sheets, covering his face and mouth, and placed him on his stomach for a nap. Tinnin didn’t check on him.

His girlfriend returned home and found August in his crib, looking pale and blue. The baby was rushed to the hospital, where he died of cardiac arrest.

Antoinette Fleming, the boy’s mother, had an order of protection against Tinnin at the time, stemming from an altercation when he allegedly smacked her. In addition to Flemming, Tinnin was barred from contact with August and the couple’s other child.
