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 took part on a chat site on Facebook. On checking out the site, detectives learned that Ochoa-Lopez had gone to the Figueroa home to collect baby clothes. Detectives then went to the home and interviewed the younger Figueroa, who eventually disclosed that her mother had just given birth to a baby. A search of the neighborhood revealed Ochoa-Lopez's car parked not far away, police said.
