VALLEJO -- Thursday was Pearl Pinson's 16th birthday -- a milestone in a young girl's life.
"Since we were little, she always loved to play in the puddles," Pearl's older sister, Rose Pinson said. "That's what we'd probably be doing."
Instead, Rose, remains vigilant, making herself available at any time and any place, to talk about Pearl and keep her in the news.
"Every single move I make is just for her, so she could be brought home," Pinson said "So her name doesn't disappear."
But since May 25, there has been no sign of Pearl.
Vallejo police say 19-year-old Fernando Castro, a stranger to Pearl, kidnapped her from a freeway overpass above Interstate 780.
Castro later died in a shootout with police. No one has heard from Pearl since.
"It's really hard not having her here, right next to me celebrating," Pinson said. "But I know where ever she's at, her spirit's here with me and we're gonna celebrate with her spirit."
Thursday, the Solano County Sheriff's Office told FOX40 there were no new leads.
In recent months, they've investigated countless leads, and chased down possible sightings of Pearl, which didn't turn out to be her.
"We still have hope that she's gonna be found. We're not gonna give up until she is found." her sister said.
It's been agonizing for the family since Pearl vanished, and especially difficult during this time of the year.
"It's gonna be hard on Christmas, because that marks the seventh months that she has been missing. And right now, our family, we're just staying positive. We're pushing each other, keeping each other up."
Rose says she'll continue to be there for her sister, and wants Pearl to know this: "Happy Birthday and I love you. And I'm gonna find you."
