A trial has begun for one of two sisters charged with first-degree murder in a decade-old killing.
Prosecutors say Sharon Huddleston, 56, confessed to killing Todd Stover by injecting him with insulin in May 2000 in Park City.
But because the drug left no traces, authorities didn't know how Stover died for 10 years. A medical examiner didn't rule the death a homicide until after Huddleston and her sister were arrested last year in Joplin, Mo.
Testimony began Tuesday morning before Sedgwick County District Judge Ben Burgess.

Sharon Edwards, Huddleston's former girlfriend, testified at an earlier hearing that she reported the killing in March 2010.
Edwards had called police in Carthage, Mo., where she was living at the time. Edwards has said she was in failing health and had told police she needed to tell someone what she knew.
Stover, 37, was found dead in the spring of 2000 after his body was dumped along a gravel road in rural Greenwood County.
An agent from the Kansas Bureau of Investigation reported that when confronted by police, both Huddleston and her sister, Rhonda Pischel, confessed to the killing.
Huddleston's trial is expected to last most of the week.
Pischel is set for trial in May.
