In Phoenix, Arizona, high school junior Alissa Turney disappeared on her last day of school.
Now, nearly twenty years later, there's been an arrest in the cold case.
Newser reports Alissa's stepfather, Michael Turney, was arrested in Mesa, Arizona on Thursday.
He's been charged with second-degree murder.
Newser reports when Alissa disappeared, Turney told police he'd argued with her because she wanted more freedom, then Alissa ran away.
Alissa's mother died of cancer before her daughter went missing.
Sarah Turney had been seeking justice for her sister for years.
I'm shaking and I'm crying.
It took almost 20 years but we did it.
