Kentucky police are searching treacherous terrain for a missing mother who was last seen stepping out of a car near a rural area.
Nicole Vanzant, 27, disappeared after an argument with her ex-boyfriend, Josh Brown, on Jan. 19, according to police. Brown said she insisted on being let out of the car following the dispute. She hasn't been seen since, despite extensive searches of the largely rural area.
But while Vanzant's parents portray their daughter as a loving mother who may have been hurt by her ex, Brown has told police that Vanzant was a drug addict who likely ran off in search of her next fix.
The missing woman's father, Rick Penix, confirmed to ABC News.com that Vanzant has a drug problem, but described her as "just a real loving daughter."
Brown, 34, said Vanzant got out of the car that Monday afternoon because she was angry that he refused to help her find pills.
Brown said he would never hurt Vanzant, whom he's dated on and off since the summer.
"Nobody wants anything bad to happen to Nicole," he told ABCNews.com. "But the truth has to come out about her character."
Citing the ongoing investigation, the Kentucky State Police won't comment on the backgrounds of either Brown or Vanzant, both of whom have reportedly had their share of troubles.
Kentucky State Police trooper Ralph Lockard told ABCNews.com that police were initially looking at Vanzant's disappearance as possible foul play. But a week into the search, they aren't so sure.
"It's still open," he said.
Brown is not a suspect at this time, he said. "We can't find anything, at this particular point, that he's hiding from us."
Vanzant continues to be classified by police as a missing person.
Vanzant, who has a 4-year-old son and was going through a divorce, went shopping with her mother at a local dollar store before getting into the car with Brown that day.
"They were just going to drive around," her mother, Tina Penix, said. "It snowed that day and it was pretty."
But while Penix alleged that Brown dropped her daughter off in a dangerous area known as McCausey Ridge, Brown said he dropped her off on the main road that leads to that area.
Tina Penix said her daughter left town once before without telling anyone, but she called within a day and told them when she'd return. She'd never just left for long periods of time without telling anyone, Penix said, and she did not have a cell phone.
"I'm just worried sick," she said.
Tina Penix hopes her daughter simply took off on her own, but said she's worried Brown might be involved with the disappearance.
"We were trying to keep her away from him," she said. "He was a weirdo."
"I would never hurt her," Brown said. "I love Nicole. I care very much about her. But the girl is hooked on pills, bad."
That night in the car, Brown said, he was trying to talk her out of getting more pills and to "grow up." When she got out of the car, Brown said, "she said 'I'll find someone to buy me a pill.'"
The Menifee County Sheriff's Office has called in several agencies, including the Kentucky State Police and a Texas-based team that searches on horseback, to help with the investigation, though a snowstorm this week has halted the ground search until the weather clears.
The rural county includes Daniel Boone National Forest and is full of trails and cliffs and difficult terrain.
