A federal jury in Durango, Colorado, has found Alonzo Gary Summa, 36, guilty of assault resulting in serious bodily injury and assault with a dangerous weapon.
The defendant, a resident of Towaoc, Colorado, cut his half-brother with a knife during an argument on August 11, 2020. The assault left the victim with a seven-inch, permanent scar.
Summa sent the victim a Facebook message that said ‘I suggest u watch where u go from now And watch your back…I’m comeing [sic] after u.’
The jury announced its verdict on November 12, 2021.
Summa was sentenced by the Honorable Senior District Court Judge Robert E. Blackburn on February 11, 2022, to serve 96 months in prison.
Summa was also sentenced to serve an additional 18 months in prison for violating his prior federal supervised release.
The case was investigated by the Bureau of Indian Affairs at the Ute Mountain Ute Indian Reservation.
Assistant United States Attorneys R. Josh Player and Jeffrey K. Graves handled the prosecution.
