Andrew Howard-French, 29, was found guilty of murder, endangering the welfare of a child and endangering an injured victim.
Firefighters and EMS personnel responded to 115 Van Wagenen Ave. July 17, 2018, to aid an "overheated infant," authorities said. Bryce Sparrow was rushed to Jersey City Medical Center, where he was pronounced dead.
An investigation revealed that the baby had suffered fatal blunt-force injuries. His death was ruled a homicide.
Howard-French was arrested a little more than a week later and charged with murder.
He faces a minimum of 30 years in prison for the murder charge alone before he is eligible for parole. He will remain in custody until he's sentenced in January.
