A 24-year-old man was convicted today of severely beating a 13-month-old boy, which led to the child's death, the Los Angeles County District Attorney's Office announced.

The jury deliberated for less than a day before finding Rodrigo Hernandez guilty of two felony counts: second-degree murder and assault on a child causing death in case TA137386.

Hernandez is scheduled to be sentenced May 11 in Department 4 of the Los Angeles County Superior Court, Compton Branch. He faces a maximum possible sentence of 25 years to life in state prison.

Deputy District Attorney Abigail Baron of the Victim Impact Program, who prosecuted the case, said on June 7, 2015, Hernandez was watching his girlfriend's toddler son while the mother was in another room in her South L.A. apartment.

Soon after, family members alerted the mother that the child was acting strangely. When the mother went to the child, the boy began to have seizures. Additionally, bruising started to develop on his body, the prosecutor said.

Paramedics were called and the toddler was taken to the hospital where he remained for several weeks until his death on June 26, 2015.

At trial, a coroner's official testified that the child died from blunt force trauma to his abdomen.

The case was investigated by the Los Angeles County Sheriff's Department.
