Maria Senorina Bolanos-Rivera, 55, was last seen leaving her Hillsboro, Oregon home on the morning of August 26, 2012. A widow and mother of six, she was described as family-oriented and in frequent contact with relatives; she left behind her wallet, identification and money and took no personal belongings. She had diabetes and required medication.

Family members thought she might have been meeting a friend and co-worker, Eloy Vasquez-Santiago. Vasquez-Santiago disappeared around the same time and later left for California and then Mexico. He returned to the U.S., was arrested in California, and was charged in Bolanos-Rivera’s death after confessing that he had stabbed her during an argument on a trip in the mountains and disposed of her body near Hagg Lake. Searches of the area did not recover remains.

The case has since included a conviction, later overturned by the Oregon Court of Appeals on the grounds that the confession was involuntary; legal proceedings and material-witness detentions followed. Does anyone have information about Maria’s last known movements or contacts on August 26, 2012?
