Devonta Lewis Jr. was a 4-month-old infant found unresponsive just after midnight on December 10, 2015, at an apartment in the 5100 block of East Sahara Avenue near Nellis Boulevard in Las Vegas. Firefighters alerted police about 12:24 a.m., and the child was pronounced dead at Sunrise Hospital at 12:34 a.m. The Clark County coroner ruled the death a homicide, citing multiple blunt-force injuries.

An arrest focused on the baby’s father, 22-year-old Devonta Lewis Sr., who had been caring for the child. He was arrested January 15, 2016, initially on a child abuse charge with substantial bodily harm. An arrest report described a skull fracture, a lacerated liver, rib fractures, and numerous bruises; prosecutors later upgraded the charge to murder as the coroner’s findings were finalized. Court documents record Lewis Sr. denying he hit the baby, saying he might have tugged the child’s shirt, while detectives documented injuries they considered inconsistent with an accident.

Relatives described shock and grief as the case moved from a medical emergency to an investigation into inflicted trauma. Does anyone have information about the hours before the medical call or the apartment timeline that could help explain what happened?
