Following a four-day trial, Matthew Thomas McGregor, a 35-year-old man from Red Lake, was found guilty by a federal jury of sexually abusing a minor. The announcement was made by Acting U.S. Attorney Joseph H. Thompson.
Court documents and trial evidence revealed that McGregor groomed and assaulted a minor under the age of 15 at a residence. His sentencing will occur at a later date.
“Sexual violence against children is one of the most devastating crimes we prosecute, and tragically, it occurs at disproportionately high rates in our tribal communities,” stated Acting U.S. Attorney Joseph H. Thompson. “This conviction reflects our unwavering commitment to standing with our native nations like the Red Lake Band of Chippewa Indians in protecting their children and delivering justice. McGregor committed an unthinkable crime against a vulnerable child. We will not tolerate it.”
Alvin M. Winston Sr., FBI Minneapolis Special Agent in Charge, said, “Yesterday, a federal jury convicted Matthew McGregor for sexual abuse of a minor.” He added that the FBI would use all available resources to protect vulnerable community members and work with prosecutors to ensure appropriate sentencing.
The case resulted from an investigation by the FBI and Red Lake Police Department. The United States Attorney’s Office praised the efforts of both agencies and valued their partnership.
Assistant U.S. Attorneys Mary S. Riverso and Rachel L. Kraker led the prosecution.
