Paramedics were called to the home early Monday morning and found Jaelin Sollow Roberto-Colley with obvious injuries and no vital signs.
Police say he was declared dead at the scene.
Two people initially charged with failing to provide the necessaries of life had that offence upgraded to first-degree murder Thursday.
Charged are 27-year-old Joel Roberto and 24-year-old Ravyn Colley.
They both appeared in court Thursday.
