The man convicted of killing abortion provider George Tiller is in a Kansas court for arguments over re-sentencing issues.

Scott Roeder's life sentence with no chance of parole for 50 years was among many vacated after the U.S. Supreme Court ruled in 2013 that juries, not judges, must decide whether aggravating circumstances existed to warrant increasing the punishment above mandatory minimum sentences.

Wednesday's hearing is expected to take up a number of routine issues, such as jury questionnaires, aggravating factors and other motions.

Roeder was convicted of first-degree murder in the death of Tiller, who was shot in a church on May 31, 2009. He testified he shot Tiller because other attempts to stop him from performing abortions had failed. Roeder also was convicted of two counts of aggravated assault.
