OCALA, Fla. -

A north Florida woman has pleaded no contest for her part in a fatal robbery.

As part of a deal with Marion County prosecutors, 22-year-old Ashley Brooke LeVelle pleaded no contest Monday to second-degree murder. She will likely get 22 1/2 years in prison. She had been facing a first-degree murder charge and a mandatory life sentence.

The Ocala Star-Banner reports that LeVelle has agreed to testify against her co-defendant, Stevin Roopnarine, at his murder trial in December.

Authorities say LeVelle met with 27-year-old LaVar Watson on Christmas night 2011 after previously meeting on a dating website. Watson was riding in the passenger seat of LeVelle's car when Roopnarine, who was sitting in the back, shot Watson.

Prosecutors say LeVelle and Roopnarine later used Watson's bank card to buy gas.
