  • Details of Disappearance
    Marlane Koue was last seen at Pizza Port in Carlsbad around 6:15 p.m. on Oct. 1, 2012. She was last seen driving her beige Dodge Grand Caravan, which has California license plate 4SHU678. There has been no activity on her cell phone or bank accounts since then. Investigators said loved ones are extremely concerned because Koue typically calls her daughter daily.

    Koue was living with a roommate on Larchwood Drive in Oceanside and estranged from her husband, Sergio Eric Castanada, 23, when she disappeared. Koue had pursued restraining orders against her husband and his grandfather, claiming they were violent toward her.

    Castanada was never arrested in Koue's disappearance, but is currently in jail in Mexico for an unrelated crime. Koue is still missing.

    Marlane Koue worked as an advocate for special needs children at the time.
