(AP) -- Kelsey Smith, of Overland Park, Kan., was taken from a Target parking lot. Her body was found four days later in a Missouri park.

Hall's plea came during what was supposed to be a routine change-of-venue hearing.

It also came a day after a judge ruled that prosecutors could still seek the death penalty for Hall, even though Johnson County District Attorney Phill Kline failed to put his address, telephone number and registration number on a legal notice.
