Details of Disappearance
Krystyn disappeared from Boise, Idaho on October 14, 1994. She left a note for her family saying she had to get away but would return in a year's time. A friend of hers said she had wanted to travel to Oregon to get away from her boyfriend.
She had had a troubled childhood and had run away from home before, but would always return home voluntarily. Prior to her October 1994 disappearance, she had never been gone for longer than a week without getting in touch with a friend or relative.
Krystyn is known to have taken a job at a hotel in McCall, Idaho after she went missing, but only for one day. Some friends and acquaintances reportedly had contact with her between October and mid-December 1994, but after that they never heard from her again. Around that time she also stopped collecting the Social Security benefits that she'd been receiving since her father's death.
Prior to her disappearance, Krystyn had been seeing Charles "Corey" Castro, who was ten years older than her. He was reportedly married, and physically abusive to Krystyn. He had allegedly threatened her to stop her from telling the police that he had assaulted her. He was one of the last people known to have seen Krystyn prior to her disappearance. Castro was on parole at the time of Krystyn's disappearance, and stated he broke off communication with her after his parole officer told him he couldn't see her anymore.
In 1998, he was convicted of sexually abusing his new girlfriend's child, and was listed on the sex offender registry as a result. He said he was questioned about Krystyn's case in 2011 and passed polygraph, and he maintained his innocence in her disappearance. A photo of him is posted with this case summary.
In January 2022, Castro was shot and killed by the police in Murphy, Idaho. Deputies with the Owyhee County Sheriff's Office were called to the address to serve him with a civil protection order, which required him to move out of the home he shared with his wife. According to the officers, when they told Castro he had to leave, he became agitated, charged them while holding a weapon, and refused to drop it when ordered, so they shot him.
Krystyn's case is now considered to be an endangered missing child rather than a runaway. Her loved ones stated she was very close to her younger brother and they don't think she would have abandoned him. Foul play is possible in her case, which remains unsolved.
