MOUNT HEALTHY, Ohio – Authorities arrested a 35-year-old man Saturday who they said "slammed" his 3-month-old baby on a floor.
The infant died at about 3:30 p.m. Sunday, deputies said.
Mount Healthy Police and the Hamilton County Sheriff's Office responded to James Phillips' home Saturday afternoon, where they found the 3-month-old not breathing, Sheriff Jim Neil and Police Chief Vince Demasi said.
Investigators said Phillips was responsible for the infant's injuries. Phillips admitted to slamming the infant on her back, deputies said, resulting in severe skull fractures and an inability to breathe unassisted.
A neighbor called 911 and attempted CPR until paramedics arrived, detectives said. The child was hospitalized in critical condition Saturday night before her death.
"[We] gotta protect our children. If our own family can't protect them we as neighbors have to come together for the children," neighbor David Webster said.
Phillips was initially charged with felonious assault and child endangering. It was unknown if further charges would be filed after the girl's death.
Deputies asked that anyone with information in this case call the Criminal Investigative Section at 513-851-6000 or CrimeStoppers at 513-352-3040.
Phillips was due to appear in court Monday morning.
