An attorney for a man who confessed to killing a Kansas abortion provider says there's no such thing as a "necessity defense" in Kansas and his lawyers don't intend to present one at his trial.

Public defender Steve Osburn said Tuesday the team has already explored that strategy and believes the approach isn't viable.

Scott Roeder told The Associated Press on Monday he plans to argue he was justified in shooting Dr. George Tiller to protect unborn children.

Roeder said he has no regrets about killing Tiller in May at the doctor's Wichita church.

The 51-year-old Kansas City, Mo., man is scheduled to go on trial in January on one count of first-degree murder and two counts of aggravated assault.
