Colorado woman Kelsie Schelling has now been missing for seven months, and family members say the expectant mother is just days away from her due date.
Schelling, 22, left Denver and went to Pueblo on the night of Feb. 4 to meet her boyfriend.
Police said according to cellphone records, Schelling made it to Pueblo, but she hasn't been seen since.
Kelsie's family said they think Schelling was pregnant when she disappeared.
"Kelsie traveled to Pueblo on the evening of February 4th at the request of her boyfriend, after she confirmed to him, earlier that day, that she was pregnant," Kelsie's aunt Beth Saxton wrote in a letter to 7NEWS. "We have not seen nor heard from Kelsie since then."
Kelsie's mother, Laura Saxton, said, "Whatever happened to her that night, also involved her unborn child. My first grandchild as well. We are doing everything in our power to find our missing loved one."
Schelling is 5-foot-4 inches tall and weighs about 120 pounds. She has three tattoos -- a Chinese symbol on the back of her neck, cursive writing on the inside of her left arm and a fleur-de-lis on her right rib cage.
Video surveillance from a Walmart in Pueblo shows Schelling’s vehicle parked in front of the store on Feb. 5 around 12:05 p.m. The car was left there overnight.
Police said the video showed an unidentified man getting into the car on Feb. 6 at 7:20 a.m. and driving off.
That video won't be released to the public, police said. It is sealed as part of the investigation.
The car was found Feb. 14 at St. Mary-Corwin Hospital. Surveillance video showed that the vehicle was parked there about 24 hours after it was picked up at Walmart.
Schelling's family said after Kelsie disappeared, her credit card was used once. They say it was used by her boyfriend, Donthe Lucas.
There is a $25,000 reward offered for solid information that leads to Kelsie, according to the Help Find Kelsie website run by her family.
