Andrew Heininge receives 25 year prison sentence following lengthy child sex crimes investigation

Today, Multnomah County District Attorney Rod Underhill announced that 36-year-old Andrew Heininge received a 25 year prison sentence for committing numerous sex crimes against two children over a two year period in Multnomah and Clackamas County.

“The resolution of this case will come as an incredible relief to the victims and their family,” said Multnomah County Deputy District Attorney Amber Kinney, who litigated this case. “Mr. Heininge caused considerable harm to these children. The state supports this fair and just resolution as it holds Mr. Heininge accountable for his actions and protects his victims from any further trauma that they could have been exposed to during trial. We are very proud of the victims for coming forward and making these disclosures.”  

Heininge appeared in Multnomah County Circuit Court on Monday and pleaded guilty to one count of rape in the first degree, one count of sodomy in the first degree, one count of using a minor in the commission of a controlled substance offense and three counts of sexual abuse in the first degree and no contest to one count of sexual abuse in the first degree. These charges were a result of a grand jury indictment that was returned in Multnomah County Circuit Court on January 29, 2018.

Heininge also pleaded guilty to two counts of rape in the first degree and two counts of sexual abuse in the first degree. These charges were a result of a grand jury indictment that was returned in Clackamas County Circuit Court on July 20, 2017.

By pleading guilty in the Clackamas County case, Heininge admits that on more than one occasion between May 2015 and July 2017, he unlawfully and knowingly engaged in sexual intercourse with a child, who was under the age of 16 and that he sexually abused that same child by unlawfully and knowingly touching a sexual or intimate part of her body.

By pleading guilty in the Multnomah County case, Heininge admitted that in 2016, he unlawfully and knowingly engaged in sexual intercourse with the same child victim from the Clackamas County case; that he engaged in sexual conduct with the child and that he sexually abused her over an eight month period; that in 2017 he unlawfully and knowingly used the child to help manufacture marijuana. He also stipulated there is enough evidence in this case that had it gone to trial, a jury or judge could have convicted him of sexually abusing a second female child who was under the age of 14.                   

Upon his release, Heininge will be on 45 months of post-prison supervision.

He will have to register as a sex offender and has been ordered to not have any contact with either victim.
