Stories: In search of Jane Doe

This is a story of a detective and his search for the identity of homicide victim known only as Jane Doe. Alameda County sheriff's Sgt. Scott Dudek committed himself to finding the identity of a teenage girl who was brutality murdered and her body dumped behind a Castro Valley restaurant in 2003. With nothing to go on but a pair of gold hoop earrings, bloody pajamas and the skeletal remains of a murdered teenager, Sgt. Dudek and his team spent three years searching for a Jane Doe and her killer.

"It's on my mind all the time," Dudek said. "I think the most frustrating thing, obviously, is it's a kid that got killed and we have no idea who she is."

Having spent over 2,000 hours on the case and along the way they've checked out 300 missing-children cases and reunited some 60 children with their parents.

In 2004, Dudek's investigation led him to the town of El Paso where he believed Jane Doe might of worked as a factory worker. El Paso is plagued with countless cases of young women being kidnapped or killed while traveling across the Mexico-U.S. border in search of work. Unfortunately, El Paso would be another dead end.

After an exhaustive three years, a tip lead the detective to a small town called Yahualica in the state of Jalisco, Mexico. With the help of local authorities, Dudek and his team finally found what they were looking for, the name Yesenia Becerra Nungaray.

Detectives are still looking for her killer but the good news is that they already know his name.
