The infant’s body was found March 12 south of Mission Road near Fremont Avenue, wrapped in plastic shopping bags with the umbilical cord attached. She had been thrown over a 6-foot chain-link fence and landed 40 feet below near the train tracks, Alhambra police officials have said. The baby, who weighed about 5 pounds, was born alive. The cause of her death was determined to be blunt force trauma. St. Therese Catholic Church in Alhambra held a funeral in the baby’s honor, and church members gave her the name Therese Rose. In court Friday, Jos Olvera, the defendant’s boyfriend in July 2005 and the father of the baby, testified that he did not know Schaefer was pregnant. Schaefer’s mother, Geraldine, who lived with her daughter at the time of the incident, also said she was unaware of the defendant’s pregnancy. “This was a tragic incident, and I’m confident justice will be served,” said Los Angeles County Deputy District Attorney Habib A. Balian of the Family Violence Division after Friday’s hearing. Schaefer will be arraigned May 14 in Pasadena Superior Court, 300 E. Walnut St., Department E.
