(AP) — Trials have been scheduled for a mother and son charged with killing a 68-year-old southern Nebraska woman.

Online court records say the trial for 41-year-old Shelley Casterline is scheduled to begin April 21 and the trial for her son, 23-year-old Andrew Casterline, is to begin May 27.

The two are charged with first-degree murder. Authorities say they stabbed to death Virginia Barone at her home in Guide Rock on Oct. 4. Her body was found the next day.

The Casterlines were arrested Oct. 5 in Newton, Iowa. Police said the two had been traveling in a sport utility vehicle stolen in Cass County, Neb., earlier that day.
