Massachusetts correction officer held without bail after allegedly having sexual relationship with 15-year-old boy, offering him gifts for sex

PLYMOUTH – A Hanson man has been found dangerous by a judge and will be held without bail, charged with sexually assaulting and trafficking a juvenile in locations across several towns, Plymouth County District Attorney Timothy Cruz has announced.

41-year-old Richard Kielczweski of Hanson, was arraigned on Monday in Plymouth District Court on charges out of Halifax and Hanson Police Departments for the alleged incidents which occurred on diverse dates from September 2025-April 2026. Kielczweski pleaded not guilty to five counts of Pay for Sexual Conduct with a Child Under 18, four counts of Rape of a Child Aggravated by 10 Year Age Difference, one count each of Rape of a child with Force, and Pose/Exhibit a Child in a Sexual Act, and two counts of Trafficking persons under 18 for Sexual Servitude.

The Commonwealth moved for a Dangerousness Hearing, which was held today. After the
hearing, Judge Shelby Smith found Kielczweski to be dangerous, and he was held. He is next expected to appear in court on the matter on May 29th.

The charges follow an active investigation by Hanson Police Department into the numerous sexual assaults and the creation of child sexual abuse material (CSAM) of a 15-year-old male victim, which occurred in Hanson, Halifax, and Middleborough. Through their investigation, police allege that Kielczweski contacted the victim via a dating app, and began a sexual relationship with the victim, meeting up at certain locations, and at Kielczweski’s residence. Kielczweksi allegedly offered the victim cash or gifts in exchange for sex.
 
As a result of the investigation, Hanson Police sought and obtained an arrest warrant for Kielczweski, and he was taken into custody by Hanson Police and Middleborough Police. 
 
A criminal complaint has been issued out of Middleborough charging Kielczweski with one count of Witness Intimidation and Enticing a Child Under 16 there. He will be arraigned on that charge tomorrow in Wareham District Court.

According to Boston 25, Kielczweski is a Correction Officer with the Suffolk County Sheriff’s Department.

The investigation is ongoing by Massachusetts State Police, Hanson Police, Middleborough Police, and Halifax Police.
