ELWOOD, Neb. -- New court documents outline how undercover agents unearthed a plot they said was put together by a central Nebraska woman to hire someone to kill five people.

A probable cause affidavit for 39-year-old Valerie Miller, of Elwood, describes how she allegedly made plans to meet up with an undercover investigator with the Nebraska State Patrol.

Those documents show the pair had planned and then met at a Walmart in Lexington. During that conversation, agents said Miller asked if the undercover agent could purchase a gun for her.

During that same conversation, court documents said Miller stated she wanted five people "not living."

Miller and the agent allegedly made a deal that he would only carry out two murders, on her ex-husband's girlfriend and the girlfriend's adult son, for a total of $2,000.

Miller is now formally charged with attempted first-degree murder.
