BILLINGS, Mont. -

A 56-year-old Billings man has been sentenced to 45 years in prison for stabbing a man to death during an argument over money.
   
The Billings Gazette reports Robert Lee Bauer was sentenced Thursday. He had earlier pleaded guilty to mitigated deliberate homicide in the December 2015 death of 40-year-old Joseph Broken Rope, a father of eight.
   
The details of the fatal stabbing were revealed during the sentencing hearing.
   
Prosecutors said Broken Rope had often purchased Bauer's state assistance food card from him, and Bauer believed Broken Rope still owed him $150. Late on Dec. 10, Bauer called Broken Rope and asked him to meet him downtown with the money.
   
Witnesses say Broken Rope hit Bauer, who then stabbed Broken Rope, piercing his heart. Bauer ran away and Broken Rope bled to death in the street.
