DENVER - The family of 21-year-old Kelsie Jean Schelling held a press conference Monday morning to release additional details regarding Kelsie's disappearance and made statements to the media.

During the press conference, Kelsie's family revealed that - at the time of her disappearance - she was eight-weeks pregnant. She had sent ultrasound pictures to family members and also to her boyfriend Donthe Lucas. Cellphone records show Donthe asked Kelsie to come to Pueblo when she got off work because "he needed to speak with her in person."

According to Laura Saxton, Kelsie's mother, she made it to Pueblo, but she never met up with Donthe.

"No one has seen or heard from her since," Saxton said. "We are not satisfied with Donthe's original account of the events leading up to Kelsie's disappearance. We are informed that he has since refused to speak with the Pueblo Police Department."

Kelsie's father, Doug Schelling, spoke also at the press conference. He expressed his concern.

"Kelsie did not talk to anyone on her phone after [Feb. 4], but text messages sent ... from Kelsie's phone to pacify family and friends," Doug said. "We do not believe that it was Kelsie texting."

Kelsie lived in Larimer Square in Denver.

"She left her apartment on the morning of Feb. 4, with every intention of returning there that evening and we know that because all of her possessions were left in her apartment," Saxton said.

Saxton says Kelsie's bank account was accessed once since she went missing - and that was by Donthe.

Police found her car in Pueblo in mid-February. Police checked the car for any indication of where she's been or who she may have been with since then.

"We have been informed and believe [the person who texted] was driving Kelsie's 2011 black Chevy Cruz on Monday night, Tuesday and Wednesday, before it was left at St. Mary Corwin Hospital employee parking lot in Pueblo on Thursday morning around 5 a.m.," Doug said. "However, surveillance tapes do not show Kelsie in her vehicle after Monday night."

"We all love and miss Kelsie so much and are more deeply saddened to know that whatever happened to her that night also involved her unborn child, my first grandchild, as well," Saxton said. "We are doing everything in our power to find our missing loved one and would expect anyone involved to do the same."

Detectives are looking for more leads. If you know anything that can help, call Pueblo Police at 1-855-4-KELSIE. The family is offering a reward of up to $10,000 to the person who provides information leading to the arrest and conviction of the suspect or suspects responsible for Kelsie's disappearance.
