Riverton Man Convicted of First Degree Murder

34-year-old Francis James Acebo Jr., of Riverton, was convicted Friday by a federal jury of first-degree murder and using, carrying, and discharging a firearm during and in relation to a crime of violence. The trial lasted five days and was held before U.S. District Court Judge Alan B. Johnson in Cheyenne.

Sentencing has been set for May 6. Acebo faces a mandatory life sentence for the first-degree murder conviction, another 10 years to life imprisonment for the firearm offense, and up to $500,000 in fines. A federal district court judge will determine and impose the sentence after considering the U.S. Sentencing Guidelines and other statutory factors.
