Factors that predict murder defendants' competence to stand trial.

One hundred sixty-three homicide case files from The Center for Forensic Psychiatry in Ypsilanti, Michigan were examined for evidence of factors associated with the outcomes of Competency to Stand Trial (CST) evaluations. Of the socio-demographic, legal, and clinical factors investigated, only three were significant. Defendants with lower IQs were more likely to be found incompetent to stand trial, and those with more property crime arrests were more likely to be found competent to stand trial. Additionally, defendants who were found incompetent to stand trial were more likely to be accused of killing an intimate or relative.
