On December 3, 2025, deputies and child [NAME REDACTED] investigation regarding a mandated report where Mason Thomas Adams, [DOB REDACTED], defendant herein, told his therapist that he had inappropriately touched his younger sister when he was a child. Defendant’s mother notified the therapist that there appeared to be more sexual abuse in the home than what he told this therapist. Defendant is 42 months and 25 days older than his sister, Child A. Child A was found in the County of Dakota, State of Minnesota.
Child A was forensically interviewed by child protection. Child A disclosed that when she was between the ages of 7 to 14 years, defendant would follow her into the shower. Defendant would force his way in and attempt to insert his penis into her anus. Child A stated she did not consent and that defendant could never fully penetrate her anus due to extreme pain. Child A disclosed defendant would use shampoo and conditioner as lubricant. Child A also disclosed defendant would touch her breasts and penetrate her vagina with his hand while on the couch and in her bedroom.
Child A disclosed defendant showed her pornography when she was 12 or 13 years old. Child A specifically disclosed that when she was approximately 12 years old, defendant “decided to experiment” on Child A and placed a marble inside her anal cavity. Child A reported defendant stopped sexually assaulting her when she was 14 years old after repeatedly telling defendant to stop attempting to sexually assault her in the shower. As defendant retreated, defendant stated, “You’ll come back. They always come back.” Defendant repeatedly told Child A that she would get in trouble if she disclosed the sexual assaults to her parents.
Since her disclosure, Child A’s and defendant’s father and their paternal grandparents have made numerous statements supporting defendant, minimizing his behavior, and concerns about potential consequences for defendant. Deputies obtained text messages from defendant to Child A from after her disclosure asking why she disclosed. Deputies attempted to interview the paternal grandparents. As deputies spoke with defendant’s 2 19HA-CR-26-780 Filed in District Court State of Minnesota 6/4/2026 grandmother, defendant appeared and stood next to his grandmother.
Defendant’s grandmother stated the defendant “is sorry for everything that took place between the two of them.” Defendant spontaneously confirmed the statement. Given the seriousness of the charged complaint, the State requests a warrant to secure conditions of release.
