Maria Coronado, 38, disappeared on June 24, 1990, while on a family vacation in Mexico. She had been traveling with her husband and three of her children, having told her oldest son on June 23 that the family was leaving Guadalajara for Manzanillo, Colima. According to her husband, the next day the couple argued, Maria stormed off, and she was never seen again. The husband and children returned to West Covina on June 28 without her.

Maria is described as 5 feet 4 inches tall, about 140 pounds, with brown hair. Despite investigations, no conclusive evidence has emerged about her whereabouts and the case remains unsolved. If anyone has information about Maria’s last movements in Guadalajara or Manzanillo in June 1990, please come forward.
