UPLAND, Calif. (KABC) – An upland mother has been formally charged with an incident in her home, which claimed her daughter's life and injured her son, who was thrown out of the balcony. A second floor, prosecutors announced Thursday.

Tierra Ortega, 25, is charged with an assault on a child, causing death, and a charge of serious bodily harm, according to a statement from the office San Bernardino County Attorney.

Emergency responders found Ezlynn Ortega, 7 months old, suffering from skull fractures on Tuesday morning in a Block 600 apartment on North Wedgewood Avenue.

His brother, Jerricho Ortega, aged one year, was reportedly thrown from the two-story building by his mother. He had a broken foot.
