It’s been four years since Dia Abrams vanished from her ranch in Mountain Center, California. Dia, 65 at the time, was last seen on June 6, 2020.

In June 2023, Dia’s case was featured in Dateline’s ‘Missing in America’ podcast series. Dateline spoke with her son, Clinton Abrams, and Keith Harper, who said that he and Dia were engaged.

Keith said he last saw Dia on the afternoon of June 6, 2020 at the ranch, where he was living and working as the ranch manager. He also served as a co-trustee of her estate.

He told Dateline he and Dia had lunch around 2:30 p.m., and then he left the home to go do some work on the property. When he returned, Keith said, Dia was nowhere to be found, but her cell phone, purse, and truck were all at the ranch, which he said was unusual for Dia.

The next day, he reported her missing.

Clinton Abrams, told Dateline in June 2023 that he did not believe that Keith and his mother were ever engaged. He also said he was suspicious of Keith and believed he may have had something to do with his mother’s disappearance. “He did something to her. To me, that would be the most simple explanation,” Clinton said.

When asked, Keith told Dateline he had nothing to do with Dia’s disappearance and that he loved her. “You love somebody, you don’t take their lives. I loved Dia Abrams,” he said in June 2023.

In November 2023, Keith was removed as a co-trustee of Dia’s estate. A few months later, a judge approved the sale of the estate.

On this fourth anniversary of Dia’s disappearance, Clinton told Dateline he is still searching for answers in his mother’s disappearance. He is hoping two rewards totaling $300,000 will prompt someone to come forward with those answers.

“I beg anyone with any information regarding what happened to my mother to come forward with any tips, leads, or information leading to her location and/or information regarding any person(s) involved in her disappearance,” he told Dateline in an email. “I send my deepest gratitude with all of my heart to those who keep the spirit of the search for Dia alive.”

Two rewards totaling $300,000 are being offered in the case by the Dia Kenshalo Abrams Trust. According to Clinton, the reward “is completely anonymous, court-approved, and is paid under a court-sealed document.”

Anyone with information is asked to contact the Riverside County Sheriff’s Office, at 951-791-3400.
