Juan Roldan (defendant) was charged with murder. At trial, the prosecution called Luz Maria Cruz, the wife of Roldan’s nephew, to testify. On cross-examination, Roldan’s counsel asked Cruz if she had ever seen people going to Roldan’s house and if she thought Roldan was generally a loner. Cruz responded saying that Roldan was “a man that never bother anybody.” On redirect examination, the prosecution asked Cruz if she was aware of Roldan’s prior conviction for first-degree murder. In doing so, the prosecution sought to rebut the defense’s implication that Roldan would never have a reason to kill someone. Roldan sought to exclude this question as impermissible character evidence. The district court permitted the question and convicted Roldan, who appealed.
