Brighton, CO — Today, 17th Judicial District Attorney Brian Mason is announcing the guilty plea and six-year Department of Corrections sentence for Matthew Mandel, 52. Mandel pleaded guilty to First-Degree Criminal Attempt to Commit Assault (F4) and Criminal Attempt Unlawful Sexual Contact (F5) in Boulder County District Court on February 17, 2022. On May 12, 2022, a Boulder County District Judge sentenced Mandel to six years in the Department of Corrections.
The 17th Judicial District Attorney's Office, which serves Adams and Broomfield Counties, was appointed as special prosecutor on this case in Boulder County.
Mandel was accused of sexually assaulting four separate victims in 2019 while he worked as a massage therapist at two different locations in Boulder County. Two of the four victims came forward after the original charges were filed in this case.
April 13, 2019:
The victim in this incident reported that Mandel used extreme pressure during her massage and maintained control of the room with his actions which frightened her. She said Mandel proceeded to uncomfortably massage her buttocks and breasts. The victim said she cried and closed her eyes until it was over.
September 18, 2019:
The victim in this incident reported that Mandel massaged her breasts, digitally penetrated her vagina and anus, brushed his erect penis against her, and performed oral sex on her before she abruptly ended the massage.
The victim in this incident came forward after the original charges were filed against Mandel. This victim reported that Mandel passionately kissed her, exposed her breast during the massage, placed his face very close to her vagina, licked the back of her thighs, and put his mouth on her nipples.
September 18, 2019:
The victim in this incident also came forward after the original charges were filed against Mandel. The victim in this incident reported that Mandel continuously adjusted her underwear throughout the massage, grazed her vagina with his hands, massaged her buttocks inappropriately, and put intense pressure on her vertebrae which caused her back to pop. For months, she said she had bruising and pain in the area where Mandel put the pressure.
"No one who goes to a massage therapist should ever have to fear or endure a sexual assault. The defendant’s conduct here was absolutely outrageous. I applaud the victims for their courage in coming forward and am grateful to my team for the just prosecution of this case," said District Attorney Brian Mason.
On February 17, 2022, Mandel pleaded guilty to:
First-Degree Criminal Attempt to Commit Assault (F4)
