VALLEJO -- Pink signs, balloons and notes are visible across a Vallejo community as another day passes without 15-year-old Pearl Pinson.
The heartbreak is palpable.
Eight-year-old Yureaia Brown can barely speak about the teenager she looks up to.
"It breaks her heart because she's so used to having her around," said Brown's mother, Desarae Reisweig-Greer.
Investigators say 19-year-old Fernando Castro kidnapped Pearl Wednesday morning from the I-780 overpass near her home.
Police say she was last seen bloody and screaming for help.
Castro was later killed in a shootout with police.
"I just never would have thought that this 19-year-old kid would do this to someone we all love and care about, and to know that she's still gone and he's been killed, that's kind of scary," said Reisweig-Greer.
Reisweig-Greer and her daughter are close with the Pinsons.
They say Castro lived around the corner.
"He could have walked across this field at any time and grabbed my child, that's scary as hell," said Reisweig-Greer.
No one was willing to speak to FOX40 at Castro's home, but other neighbors say they had issues with the young man.
"I have a 16-year-old daughter. He would hoot and holler and make noises to try to get her to respond to him over the fence," said neighbor Judy Wendte.
Wendte says her heart breaks for the Pinson's as they wait for answers.
"I just couldn't imagine going through that," Wendte tearfully said.
At Jesse Bethel High School, classmates worry about the freshman who hasn't been there for nearly a week.
"Everybody's talking about it, they hope she comes home," said classmate Alexa Fletcher.
"People should know that she's a kid, and she's probably terrified with the situation she's going through," said classmate Jalen Bradford.
After searching hundreds of miles across the state, investigators are asking for more help.
If you've seen Pearl's face, if you've seen her purple and green backpack, come forward and help bring Pearl home.
