Summary based on the NamUs case record (MP18159) and 5 other sources
Marlane Koue Castaneda, a 54-year-old woman from Oceanside, California, was last seen on October 1, 2012, at a Pizza Port restaurant in Carlsbad. Marlane had regular communication with her daughter, Maya, but on that day, the phone calls stopped, raising immediate concerns. Marlane’s cellphone and bank accounts have shown no activity since her disappearance, which further alarmed her family.

Marlane was last seen driving a beige Dodge Grand Caravan. Despite the lack of any immediate evidence of foul play, the circumstances of her disappearance have left many unanswered questions. Her estranged family dynamics were complicated; she had secured a three-year restraining order against her husband’s grandfather earlier in 2012 due to alleged physical abuse. Marlane's husband, Sergio Eric Castaneda, has cooperated with investigators, but he has been difficult to reach for further inquiries.

Authorities are still seeking any information regarding Marlane’s whereabouts, and her case remains unsolved. Described as being 5'5", 160 lbs, with brown hair and eyes, Marlane's case is classified as a missing person investigation.
