Cesar Pedroza, 21, was booked at Central Detention Center Monday for assault on a child causing coma.
Investigators said Pedroza was taking care of his three children, ages 4, 2 and 10 weeks, on Saturday when he called 911 to report that while he was feeding his baby some formula, she stopped breathing.
Deputies responded to the 41200 block of Lahontan Drive. The young victim was taken to Loma Linda University Medical Center, where doctors discovered that she had extensive brain trauma, which was suspected of being caused by abuse.
Authorities conducted an investigation and subsequently arrested the father. His bail was set at $500,000.
Anyone with information regarding this investigation was asked to contact the San Bernardino County Sheriff's Crimes Against Children Division at (909)387-3615.
