Gary Ridgway, known as the "Green River Killer," was transferred to King County Jail in Washington state for unknown reasons.

Ridgway is a notorious serial killer who pleaded guilty to murdering 49 women between 1982 and 1998.

He was previously serving his life sentences at Washington State Penitentiary.

The move to a lower-level jail has sparked questions, but officials have not disclosed the reasons.

One of Ridgway's victims, a 15-year-old named Lori Anne Razpotnik, was identified almost 40 years later through DNA testing.

Ridgway confessed to 48 killings in 2003.

Sarah and Jacob Hoggle went missing on September 7, 2014.

New age-progression photos of the siblings have been released by the National Center for Missing and Exploited Children.

Three years after their disappearance, their mother Catherine Hoggle was indicted on two counts of murder, although the children have never been found.

Their father, Troy Turner, continues to search for them.

Sarah was 3 years old and Jacob 2 when they went missing.

NCMEC remains dedicated to finding them, emphasizing the importance of keeping hope alive.

Anyone with information is urged to contact NCMEC at 1-800-843-5688 or Montgomery County Police at 301-279-8000.

In 1986, an 11-year-old vanished from a quiet Nebraska suburb, sparking a major search. Despite hopes fading, the worst was confirmed a week later. Even after 38 years, new leads still emerge.
