Texas Man Found Guilty of Sexually Assaulting a Passenger During a Flight Sentenced to Prison

SALT LAKE CITY, Utah – Robert Sutherland MacLean, 59, of Frisco, Texas, was sentenced to 15 months’ imprisonment after he was convicted by a jury in July of abusive sexual contact in the special aircraft jurisdiction of the United States.

In addition to MacLean’s term of imprisonment, Senior U.S. District Court Judge Dale Kimball imposed a term of three years’ supervised release, a fine of $10,000, and ordered MacLean to pay $7,261.60 in restitution.

According to court documents and evidence presented at trial, on March 1, 2022, during an approximately 3-hour flight from Chicago to Salt Lake City, MacLean repeatedly sexually assaulted the victim seated next to him in the first-class cabin of a United Airlines Flight. MacLean also made calculated and sexually laced statements to the victim throughout the duration of the flight.

According to court documents, MacLean has a history of misconduct on an airplane and was cited by the Federal Aviation Administration civilly for interference with a flight crew where his reported conduct was similar to conduct at issue in this case in which he was convicted.    

The case was investigated by the FBI Salt Lake City Field Office.

Assistant United States Attorneys Michael Kennedy and Bryan N. Reeves of the U.S. Attorney’s Office for the District of Utah prosecuted the case.
