Eva Susan West, 28, vanished from her Oklahoma City home after being seen by a friend on the evening of June 14, 1985. Known by some as Pete, she was petite at about 5 feet 5 inches and 95 pounds, with long dark brown hair, brown eyes, a scar at the base of her neck, pierced ears and no right earlobe. When she disappeared her fingernails and toenails were believed to be painted.

A few days after her mother reported her missing, a caller claiming to be Eva left a message at the hospital where her mother worked saying she was alright; the caller was never identified. Eva’s cream-and-brown two-door GMC truck was seen being driven by her boyfriend in the days after she vanished; he continued to use it until he was arrested on unrelated charges and the truck was later recovered by Eva’s mother. Investigators have long considered a possible drug connection and foul play, but no suspects have been publicly named and the case remains open with the Oklahoma City Police Department Cold Case Unit.

If anyone knew Eva, her boyfriend at the time, or saw the truck after June 14, 1985, can you share what you know?
