Salt Lake City, Utah – A federal jury in Salt Lake City returned a guilty verdict today against a Texas man after he grabbed and groped a female passenger multiple times without her consent while onboard a late-night flight from Chicago to Salt Lake City.

Robert Sutherland MacLean, aka “Bobby,” 59, of Frisco, Texas, was charged by indictment on April 18, 2023, with abusive sexual contact in the special aircraft of the United States.

According to court documents and evidence presented at trial, on March 1, 2022, while in flight, MacLean made calculated and sexually laced statements to a stranger seated next to him while he sexually assaulted her multiple times in the first-class cabin.

“Mr. MacLean unlawfully and illegally imposed his will upon another person— sexually assaulting her over and over again on that late night flight,” said prosecuting attorney Bryan N. Reeves of the U.S. Attorney’s Office, during the trial.

MacLean’s sentencing hearing is scheduled for October 1, 2025 at 10:00 a.m. before Senior U.S. District Court Judge Dale A. Kimball at the Orrin G. Hatch United States District Courthouse in downtown Salt Lake City. 

Acting United States Attorney Felice John Viti of the District of Utah made the announcement.

The case is being investigated by the FBI Salt Lake City Field Office and assisted by the Salt Lake City Police Department.

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