GIrl, 15, missing two years after abduction

VALLEJO, Calif. (KTVU) - Friday marks two years since 15-year-old Pearl Pinson was kidnapped in Vallejo. The prime suspect in her disappearance was killed in a police shootout. Since then, no one knows where she is.

Pinson was walking to a school-bus stop near Vallejo when she was accosted by a man near a footbridge over Interstate 780.

"That one little piece can help find her," said her 19-year-old sister Rose Pinson. She says although the suspect is dead, someone out there knows what happened to her sister and where she may be

"If you know anything about where he took her, what he did with her or anything, even a small rumor that you think is not important, call. Call right away," she said.

It was on may 25, 2016, when a witness saw Pearl Pinson being dragged by a man.

"She's on the ground and she's bleeding from her face. And she yells to him, 'Call the police, he's trying shoot me,' " said Solano County sheriff's Detective Sean Mattson, the lead investigator in the case. 

"He points the gun at him. So witness runs this way to go, because he didn't have his phone. He flags someone to call 911. As he's running, he hears a shot," Mattson said

A day later, the suspect, 19-year-old Fernando Castro was killed in a shootout with police in Solvang in Santa Barbara County. Any secrets he may have had, he took with him to his grave.

"We don't know where she is. She could be alive, or obviously not. But we have to work everything, keep an open mind," Mattson said.

A day after the kidnapping, investigators later learned, CCstro got gas in a Saturn in Bodega Bay. He may have then headed to Jenner. A couple hours later, traffic cameras spotted the car heading west on the Richmond-San Rafael Bridge and on Sir Frances Drake Boulevard in Marin County.

The car was later spotted heading south on the Golden Gate Bridge hours before the deadly shootout in Santa Barbara County.

No matter what the outcome, Pearl's family just wants answers.

"We have every door open," said Rose Pinson. "We're ready for anything that comes our way, good or bad. We just want closure. We want to find her. We want to find out what happened to her."

Sheriff's investigators are asking the public to think back to Memorial Day weekend 2016 and to forward to them any tips or information in the case. Tips can be called in anonymously to (707) 784-1963.
