LOS ANGELES — Regina Morris’s sister had been missing for four years before she saw her again—in a photo taken from the home of an accused serial killer.

In 2009, LAPD homicide detectives showed her one of the hundreds of Polaroids from Lonnie Franklin Jr.’s home in South Los Angeles. Police arrested him on July 7, 2010, accusing him of murdering 10 people and attempting to murder of one survivor.

“The picture they showed me was my sister RoRo,” Morris told The Daily Beast, referring to the nickname she used for her older sister, Rolenia Morris, who was 29 when she disappeared on Sept. 10, 2005.
