PORTLAND, Ore. (AP) — An attorney for Thurston High School shooter Kipland P. Kinkel will augment an appeal of his nearly 112-year prison sentence by using a U.S. Supreme Court ruling on juvenile life in prison sentences.

The Supreme Court Monday extended its ban on mandatory life in prison without parole sentences for anyone who committed a murder before age 18.

At age 15, Kinkel killed his parents. He later went to his high school cafeteria in Springfield, fatally shooting two students and wounding about two dozen others in May 1998.

The 33-year-old is being held at the medium-security Oregon State Correctional Institution in Salem.

The Oregonian reports ( Kinkel’s attorney Andy Simrin says the high court’s ruling might help Kinkel. Simrin expects plans to file a related memorandum with the Oregon Court of appeals.
