According to an arrest affidavit, the alleged assaults started in the summer of 2009. The 12-year-old victim's step-dad Kevin Carothers and her mother Theresa Carothers were living in Denver when Kevin allegedly started inappropriately touching his step-daughter in her "personal area."
The girl says Kevin told her not to tell anyone after the incident.
After she started school, the victim claims Kevin had sex with her in her mom's bedroom when she was 12 years old. She says Kevin came into the bedroom, pushed her flat onto the bed, took her pajamas off and had intercourse with her.
In the arrest affidavit, she told officers that "it hurt a lot and his hands were on her hips" at the time of the assault.
In December 2009, Kevin, Theresa and the victim moved in with Kevin's parents. According to the victim, after they moved, her mother joined in the assaults. Some of the incidents happened in the house while, at other times, the victim claims they happened in various hotel rooms.
Police also claim Kevin and Theresa took lewd photos of the victim and would reportedly text each other the photos with "sexually explicit" messages - including details on what they were allegedly going to do to her. During the photo sessions, the victim was either 13 or 14 years old, according to the arrest affidavit.
"This is really a disturbing case in that the allegations involve a mother and a step-father sexually assaulting a young girl over the course of at least a couple of years," Denver District Attorney spokeswoman Lynn Kimbrough said. "At this point, we've formally charged the step-dad Kevin ... and there's an arrest warrant that's been issued for Theresa ... but she is at large and she's wanted."
Police also interviewed a witness who said Kevin inappropriately touched the victim on multiple occasions and also experienced some assaults herself. The witness says Kevin touched her breasts many times. At one point, the witness claims Kevin asked her to show him her private parts.
Kevin has been charged with sexual assault on a child by a person in a position of trust and incest. Kevin has a criminal history in Denver. In 1997, he was charged with sexual assault on a child. He served time for attempted sexual assault from December 1997 to March 2000. He was discharged from parole in July 2001. In 2007, he faced charges on vehicular theft. A family member told 9NEWS Carothers had to register as a sex offender in Missouri, but 9NEWS has not been able to find Carothers as a registered sex offender in Missouri, Colorado or nationally.
There is a warrant for the arrest of Theresa, but it is unknown at this time what charges she will face once arrested. Police need help finding Theresa. If you have information regarding her whereabouts, call Denver Police at 720-913-2000.
"I know that these allegations are very disturbing," Kimbrough said. "Sexual assault on a child is very disturbing in and of itself, but when the allegations involve the victim's mother, I know people will think 'Oh my God, how? A normal person doesn't think that way.'"
9NEWS Reporter Anastasiya Bolton spoke with Kevin's family members who said they were "not surprised" by the crimes he allegedly committed. According to his family, "love and affection was not top of the list when he was growing up. It doesn't surprise me he's ended this way."
