MILWAUKEE, Wis. (WTAQ) - Prosecutors said an elderly Milwaukee man shot his cousin to death after he noticed that cigarettes were missing from a pack he left on a table in their home.

Authorities said it was the last straw in a series of disagreements between 70-year-old Orteal Tyler and his 50-year-old cousin Mark Chambers.

Tyler was charged Wednesday with first-degree intentional homicide, and a judge set his bond at $150,000.

Prosecutors said the two argued a number of times about money, and Chambers had made threats to Tyler. After another argument on Sunday, authorities said Chambers was lying on a couch when Tyler saw several cigarettes missing from a pack he left in the kitchen. Officials said Tyler then grabbed a rifle and shot Chambers 7 times.

Tyler is charged in Milwaukee County with first-degree intentional homicide. He’s due back in court next Thursday, when a judge will decide if there’s enough evidence to order a trial.
