Police said detectives didn’t begin to piece the case together until May 7 — two weeks after Ochoa-Lopez went missing — when a friend of the teenage mom mentioned that she had joined a chat site on Facebook. On checking out the site, detectives learned Ochoa-Lopez had gone to the Figueroa home. Detectives went to the home and interviewed the younger Figueroa, who eventually disclosed that her 46-year-old mother had just given birth to a baby. A search of the neighborhood revealed Ochoa-Lopez’s car parked not far away, police said.
