A Rehoboth man is facing federal charges after investigators say he drove to Rhode Island to meet someone he thought was a 15-year-old, who turned out to be an undercover officer. Federal prosecutors say the arrest is one piece of a wider child-exploitation sweep tied to security preparations around World Cup events. Richard Lallier, 34, is now charged in a case that authorities say grew out of online messages and a planned in-person meetup.

How investigators say it unfolded

According to court documents and reporting by Daily Voice, Lallier allegedly began messaging on June 16 with a person he believed was a 15-year-old, sent explicit sexual content, and talked about meeting to have sex. Local outlets report that he then drove from Rehoboth into Rhode Island for that arranged meeting and was arrested on June 17 as part of the broader operation, according to Fall River Reporter. He was later arraigned in federal court and ordered held without bail after the arrest, reporters noted.

Charges brought in federal court

Federal prosecutors have charged Lallier with attempted enticement of a minor to engage in sexual activity, attempted interstate travel for illicit sexual conduct with a minor, and attempted transmission of obscene material to a minor, according to reporting by the Boston Globe. The counts were filed in U.S. District Court in Rhode Island. Court records show the case remains open, and Lallier is presumed innocent unless and until prosecutors prove the charges beyond a reasonable doubt.

Operation Red Card and the regional sweep

Officials say the arrest is part of “Operation Red Card,” a multi-agency push led regionally by state police and federal partners that targets trafficking and child exploitation. The FBI Boston described coordinated work by its child-exploitation and human-trafficking task force that resulted in arrests in both Massachusetts and Rhode Island in mid-June, tied to related stings and ongoing investigations.

What prosecutors and investigators said

First Assistant U.S. Attorney Charles C. Calenda stressed that responsibility in these cases, in the view of prosecutors, lies squarely with adults who seek out minors. FBI officials described child-exploitation cases as among the bureau’s highest priorities. Those comments were reported by Daily Voice, which also carried statements from prosecutors and federal agents on the arrests.

Legal context and possible penalties

Federal law treats the alleged conduct as a serious offense. Title 18 U.S.C. § 2422(b) criminalizes coercion and enticement of a minor and carries a substantial mandatory minimum sentence in some situations, while 18 U.S.C. § 2423 addresses interstate transportation and related conduct involving minors and sexual activity. Another statute, 18 U.S.C. § 1470, makes it a crime to knowingly transfer obscene material to someone under 16 and also includes potential prison time. The statutory language can be found here: 18 U.S.C. § 2422, 18 U.S.C. § 2423, and 18 U.S.C. § 1470.

Authorities have emphasized that undercover cases often rely on decoy accounts, and that charges can still be filed even when the supposed minor is an officer or agent. Courts have repeatedly upheld prosecutions in these sting operations under the federal enticement laws. Local police and federal prosecutors are urging anyone with information about potential trafficking or exploitation to contact the national hotline or reach out directly to local law enforcement.

The investigation and related prosecutions remain active. Future filings and hearing dates are expected to appear on the federal court docket as the U.S. Attorney’s Office and Rhode Island authorities move the case forward.
