LOS ANGELES – The death sentence of the "Grim Sleeper" serial killer put to rest a case that spanned more than three decades, but it leaves another mystery wide open.

Police are still trying to identify 33 women whose snapshots were found in Lonnie Franklin Jr.'s home after his arrest.

Police and prosecutors say they suspect Franklin could have killed as many as 25 women, and those in the photos could be additional victims.

Franklin was sentenced to death Wednesday for murdering nine women and a teenage girl from 1985 to 2007.

When he was arrested in 2010, police discovered nearly 1,000 photos of women or teenage girls — many nude and some who appeared to be unconscious or dead — hidden in his house. The photos included snapshots of some victims.
