FLORENCE — A 20-year-old Red Rock man has pleaded not guilty in the killing of his 19-year-old girlfriend.

The Pinal County Attorney's Office says Ramiro Delcid was arraigned Friday on a charge of second-degree murder in the Oct. 14 killing of Dina Dicochea.

Previous news reports have said Dicochea had recently moved from Tucson to Red Rock.
