Leona Kinsey disappeared from her home on Hall Street in La Grande, Oregon on October 25, 1999, and has not been seen or heard from since. All of her possessions, including her beloved pets, were left behind in her trailer home. Her 1980s model GMC Jimmy was discovered in a parking lot at an Albertson's store four days later. The car had been damaged, but there was no evidence of a struggle or any clues to her disappearance.

Kinsey's loved ones suspect Juan "John" Pena-Llamas may be involved in her disappearance as she was planning to meet him on the night she went missing. Pena-Llamas is considered a person of interest by the police, but little is known about him. He was arrested for theft in 2006 and was later deported to Mexico as he was undocumented.

Photos of Pena-Llamas are available on this case. He is described as a Hispanic male with black hair and brown eyes, standing 5'5 tall and weighing 135 pounds. He may use various aliases and was known to have a criminal history that includes physical assault, third-degree rape, and third-degree sodomy. It's believed that he may have been involved with a Mexican drug cartel.

Kinsey, who owned a landscaping and yard care business, enjoyed outdoor activities such as hunting, fishing, and camping. Her daughter stated that she was happy with her life and wouldn't have left or abandoned her pets. Despite ongoing investigations, Kinsey's disappearance remains unsolved, and authorities are urging anyone with information to come forward.
