Jonathan Lefman Convicted of Abusive Contact with Teen on Flight

Jonathan Alan Lefman, a 48-year-old resident of Newton, Massachusetts, has been convicted of abusive sexual contact with a minor aboard a flight from Puerto Rico to Boston. The conviction was delivered on October 16, 2026, following a three-day jury trial in the U.S. District Court.

Lefman was found guilty of making repeated sexual contact with a 17-year-old female passenger during a JetBlue flight on August 30, 2024. The incident occurred while the flight was en route from San Juan, Puerto Rico, to Boston, and continued while the aircraft was on the ground waiting to deplane.

Details of the Incident

According to the U. S. Attorney's Office, Lefman engaged in abusive sexual contact by working his hand between the back and bottom of the seat in front of him, where the minor victim was seated, and touched her buttocks without her consent.

The minor victim managed to capture video evidence of Lefman's fingers protruding between the seats using her cell phone camera. This video was later shown to a JetBlue supervisor by an adult female family member of the victim, who reported the incident.

The U. S. Attorney Leah B.

Foley emphasized the seriousness of the crime, stating, "No one should have to fear being sexually assaulted, whether in the air or on the ground." Ted E. Docks, Special Agent in Charge of the FBI Boston Division, praised the courage of the young victim and reiterated the FBI's commitment to protecting children from such predatory conduct.

Legal Proceedings and Sentencing

Lefman was initially arrested and charged by criminal complaint in February 2025, followed by an indictment by a federal grand jury in March 2025. The charge of abusive sexual contact while in the special aircraft jurisdiction of the United States carries a potential sentence of up to two years in prison, five years to a lifetime of supervised release, and a fine of up to $250,000.

U. S. District Court Judge Julia E.

Kobick has scheduled Lefman's sentencing for January 12, 2027. The sentence will be determined based on the U. S.

Sentencing Guidelines and relevant statutes.

The case was prosecuted by Assistant U. S. Attorneys Elianna J.

Nuzum and Julissa Walsh of the Criminal Division, with assistance from the FBI, Massachusetts State Police, and Boston Police Department. The conviction serves as a reminder of the legal consequences for those who exploit vulnerable passengers in confined spaces such as aircraft.
