RUMFORD POLICE ANNOUNCE GRAND JURY INDICTMENTS AGAINST TWO MEN IN SEXUAL ASSAULT INVESTIGATION INVOLVING FIVE JUVENILE GIRLS
RUMFORD, MAINE — October 29, 2026
The Rumford Police Department announces that two men have been indicted by an Oxford County Grand Jury on multiple felony and misdemeanor charges stemming from an investigation into alleged sexual assaults involving five juvenile girls, ages 12 to 14, in Rumford earlier this year.
On August 3, 2026, Rumford Police initiated an investigation following a report of a possible sexual assault involving a minor at the Swainbrook Apartments on Spruce Street in Rumford.
As investigators began examining the circumstances surrounding the reported incident, the investigation expanded significantly after police learned that five juvenile girls, ranging in age from 12 to 14, were allegedly involved.
According to the investigation, the juveniles encountered an adult male in Rumford whom they did not previously know and subsequently accompanied him to an apartment at the Swainbrook Apartments complex. Once there, the juveniles attended a gathering with that individual and a second adult male, who was also previously unknown to them.
During the gathering, the two adult males allegedly furnished alcohol and ma*****na to the juveniles and engaged in unlawful sexual acts involving minors.
Rumford Police conducted an extensive investigation into the allegations, which included gathering evidence, interviewing witnesses, and examining the circumstances surrounding the reported offenses.
On October 14, 2026, evidence developed during the investigation was presented to the Oxford County Grand Jury, which returned indictments against both adult males. Arrest warrants were subsequently issued based upon those indictments.

DIEGO RAMIREZ, 29, of Swainbrook Apartments, Rumford, Maine, was indicted on the following 12 charges:

NKIALUZITU MAYINGI, 31, of Preble Street, Gorham, Maine, was indicted on the following 12 charges:
- Five (5) counts of Gross Sexual Assault — Felony
- Four (4) counts of Unlawful Sexual Contact — Felony

- One (1) count of Endangering the Welfare of a Child — Misdemeanor
- One (1) count of Furnishing Liquor to a Minor — Misdemeanor
PRIOR ARRESTS AND CUSTODY STATUS
RAMIREZ was initially arrested by Rumford Police on August 9, 2026, and charged with preliminary felony sexual offenses and child endangerment in connection with the investigation. Following his arrest, RAMIREZ was released on bail pending further court proceedings and presentation of the case to the grand jury.
Investigators also developed probable cause to charge MAYINGI with offenses arising from the same incident. However, police were initially unable to locate MAYINGI, prompting Rumford Police to obtain warrants for his arrest.
On September 16, 2026, MAYINGI was subsequently located and arrested in Cumberland County on those warrants. He was transported to the Oxford County Jail, where he remained in custody, unable to post bail, when the grand jury returned the indictments on October 14.
On October 27, 2026, RAMIREZ was arrested again, this time by deputies from the Oxford County Sheriff's Office in Buckfield, Maine. Deputies encountered RAMIREZ while conducting an unrelated investigation and took him into custody on the outstanding arrest warrant issued following the October 14 grand jury indictment.
The charges outlined in the October 14 grand jury indictments represent the formal criminal charges upon which the State of Maine is proceeding with prosecution against both defendants.
STATEMENT FROM THE CHIEF OF POLICE
"The allegations in this case are deeply disturbing. Five young girls, ranging in age from just 12 to 14, were allegedly provided alcohol and drugs and subjected to serious sexual assaults by adults. Our investigators have worked diligently to establish the facts, identify those responsible, and bring this case before the grand jury. Protecting children from sexual abuse and assault is among our highest responsibilities, and we take that responsibility very seriously.
This case also serves as an important reminder to parents, teenagers, and younger children about personal safety and the dangers of placing their trust in people they do not know. Accepting rides from strangers, accompanying unfamiliar adults to private residences, or going places without a parent's knowledge or approval can expose young people to serious risks. What may initially seem like an innocent or harmless situation can quickly become something very different.
Young people are naturally curious, increasingly independent, and sometimes more confident in their ability to recognize danger than their life experience might justify. That's part of growing up. But the world can be a dangerous place, and not everyone they encounter has good intentions. It's our responsibility as parents, guardians, and adults to help them understand those realities before they find themselves in a situation they are unprepared to handle.
We also live in a very different world today. Social media, instant messaging, and other technology have made it easier than ever for young people to connect with others, including people they may know very little about. These technologies have changed how young people communicate, socialize, and form relationships, and they have created challenges that many of us never faced growing up.
I strongly encourage parents and guardians to have frank, direct, and ongoing conversations with their children about personal safety, recognizing potentially dangerous situations, and making informed decisions. Know who your children are spending time with, where they are going, and who they are communicating with. Most importantly, make sure your children know they can call you for help, at any time and under any circumstances, without fear of being judged or punished for asking. Their safety must always come first.
I also want to emphasize that these dangers are not unique to Rumford. They exist in communities large and small, whether in Rumford, Maine, or New York City. Rumford is a good community, filled with hardworking, caring people and families who look out for one another. The alleged criminal actions of two individuals do not define who we are as a town, nor should they overshadow the many good people who call this community home. No community is immune from criminal behavior, and acknowledging these realities does not mean our community is unsafe. It means we must remain informed, involved, and vigilant.
Finally, I want to be absolutely clear that responsibility for the alleged sexual assaults in this case rests with the adults accused of committing them, not with the children involved. The purpose of sharing these safety reminders is not to place blame on victims, but to help prevent other children and families from experiencing similar harm.
Our responsibility as a police department extends beyond investigating crimes and bringing offenders before the courts. It also includes educating the public, helping families recognize potential dangers, and working together to keep our community and our children safe."
— Chief of Police, Rumford Police Department
Because this case involves juvenile victims and allegations of sexual offenses, the Rumford Police Department will not release information that could identify the children involved or compromise their privacy, and ask that the community do the same.
An indictment is a formal accusation of criminal conduct and is not a determination of guilt. Both defendants are presumed innocent unless and until proven guilty in a court of law.
