1 Forensic assessment instruments Review the case of the murder of Travis Alexander by Jodi Arias. Name Course Instructors Name Date

2 PART 1 Forensic assessment instruments used by Dr. Janeen DeMarte's expert witness testimony on the Murder of Travis Alexander by Jodi Arias Focusing on expert witness testimony of Dr. Janeen DeMarte in the murder of Travis Alexander by Jodi Arias, intelligence, Competence to stand trial, and personality disorders are the evident three forensic assessment instruments. The first rebuttal witness for prosecutor Juan Martinez, psychologist Dr Janeen DeMarte after her assessment, described Jodi Arias as an immature, strange person with borderline personality disorder (Jones, 2015). In her intelligence, personality disorder, and ability to stand trial, DeMarte explains the unstable and intense interpersonal relationship of Jodi, the identified disturbance, affective instability, suicidal behavior, feelings of emptiness, creativity, and the most significant aspect of the case, which was the inappropriate intense Jodi's anger. Up to that point, the "inappropriate, intense anger" was a Jodi side that hadn’t yet been discussed in court. Reading an email that Jodi had sent to Travis DeMarte reveals how her anger was destructive; she kicked holes in walls, smashed windows, broke things, and kicked doors down. '' it hurts people, and it hurts me," so the assessment on Competence to stand, trial stands was Jodi encountering this feeling on a colossal scale when she came to realization Travis did not want to be with her and did it contribute to her actions. On intelligence, Martinez stated that Jodi had PTSD and also had memory issues after giving three different confessions. One that she did the murder act; the next confession, she said she does not remember; the third confession, she said she blacked out, which the psychologist associates with Dissociative amanita, meaning she

3 blacked out as triggered by the post-traumatic stress disorder (Roberts et al., 2022). DeMarte also testifies Jodi was lying about her memory fog after killing Travis. However, DeMarte believes Jodi had spanning suicidal thoughts from 1995 and emptiness feelings. The reliability and validity of the three assessment instruments on expert witness testimony of Dr. Janeen DeMarte is in question since the defense lawyer invalidates DeMarte’s Competence by referencing the Reference on Manual on Scientific Evidence (RMSE), claiming that DeMarte's assessment cannot be treated as of an expert on such heavy case as she had less than five years of forensic assessment experience (Jones, 2015). It is crucial to have a thorough understanding of assessment instruments in the forensic role as they provide information necessary to make valid and reliable legal decisions regarding the relevant capacities of an individual, which underlies the specific criminal and civil questions like Competence to stand trial or sanity in time of the offense (Otto & Heilbrun, 2019). The use of forensic assessment instruments helps mitigate the examiner's bias and error, hence permitting such meaningful context for comparisons over time for different examiners.
