Kimberly Dawn Vialpando was 35 when she was last seen in Pocatello, Idaho, on May 6, 2000. An employee at American General Finance, she failed to show for work and was reported missing by her sister on May 8 after family and friends could not reach her. She left home without personal belongings or her purse and did not have medication she needed.

Two juveniles reportedly saw her arguing with an unidentified man at Memorial Park on the day she vanished. Thirteen days later, on May 19, her pickup truck was found abandoned in the 300 block of North Johnson Avenue. A five-hour search of the Portneuf River from Memorial Park to American Falls on May 21 turned up no evidence tied to her, although search dogs showed interest in several spots near the river.

Vialpando is described as a Caucasian female, brown hair, blue eyes, 5 feet 2 inches, about 115 pounds, with a scar on her left ankle and multiple tattoos including a shooting star on her right shoulder. She may also use the last names Gonzales or Keller. Law enforcement questioned people in her inner circle, including her estranged husband, but few details have been released and the case remains unsolved.

If anyone knew Kimberly, saw her around Memorial Park or North Johnson Avenue in May 2000, or has information about that day, please come forward.
