ANDERSON, Ind. — Court documents reveal a 32-year-old Anderson mother befriended a 14-year-old runaway by offering him weed and a place to stay. But she opened more than her front door to the child, inviting him into her bedroom where she is accused of not only having sex with the boy but gaslighting him into thinking she was pregnant with his baby. Court docs: Fishers man molested, exploited young girls Amber Koopman is charged with four counts of sexual misconduct with a minor, as both Level 4 and Level 5 felonies. She also faces misdemeanor charges of contributing to the delinquency of a minor and possession of marijuana. Amber Koopman According to court documents, the allegations against Koopman found their way to police on Sept. 18. The victim told police he had been living "on the run" in Anderson after running away from home. He then started talking with Koopman who offered to smoke weed with him. Koopman ended up offering more, according to the victim, taking the boy inside and stripping off her clothes. Investigators said Koopman was aware of the child being underage but continued to have sex with the boy. After the child was taken away from Anderson, she even claimed to be pregnant with the child's baby, causing the juvenile to run away from his home once again. This isn't the first time Koopman allegedly gaslit the boy into thinking she was pregnant, according to the victim.

In these love letters, Koopman acknowledged the sexual acts between her and the juvenile, evening pining for future encounters. "I can't wait to have sex with you again," Koopman allegedly wrote to the 14-year-old. "Remember, don't tell or we'll both be in trouble," she added in the P.S. Court documents reveal that when officers confronted Koopman outside her home she accused teenagers of harassing her on Instagram and calling her a pedophile and claiming she was pregnant with the juvenile runaway's child. When police asked Koopman about her relationship with the victim, she claimed the boy was "just like one of my kids." Koopman at first denied having any sexual encounters with the juvenile, telling police: "That's nasty." But investigators confronted Koopman with the letters she wrote the child, including ones where they spoke about having sex. This is when police said that Koopman admitted to having sex with the underage boy. "I was drunk," she claimed. But Koopman then later claimed she couldn't drink due to having lupus. When questioned about the contradiction, Koopman told officers she was under the influence "of other things."
