PASADENA — A judge Wednesday sentenced a Duarte man convicted of murdering his brother last year in a parking lot outside the Rose Bowl to spend the rest of his life behind bars, officials said.

Clifton Cass, 57, received a sentence of 100 years to life in prison from Pasadena Superior Court Judge Janice Croft, court officials said.

A jury convicted him Feb. 24 of the Feb. 28, 2011 slaying of 57-year-old Victor Cass of Duarte. He was convicted of first-degree murder and being a felon in possession of a firearm, and the jury also found true a special allegation that he personally used a handgun in the killing.

Clifton Cass lured his brother to the Rose Bowl with the ruse of a drug deal, then fatally shot him before trying to decapitate the body, prosecutors argued.

He was angry because he believed Victor Cass was being disrespectful to their mother.

Clifton Cass was jailed in April of last year and police found him with drugs and weapons during a traffic stop, officials said. A search at his home turned up more drugs and guns.

A second suspect in the case, 60-year-old Dwayne Sims of Duarte, pleaded no contest late last year to charges of being an accessory after the fact and being a felon with five previous convictions in possession of a firearm, Los Angeles, district attorney’s officials said.
