The case being analyzed for the final project is that of Mr. Davis, a Muslim immigrant
that was diagnosed with paranoid schizophrenia. He was charged and later convicted of capital
murder following a violent incident that left one boy dead, and another injured. This case
emphasizes the complex issues that involve mental illness, competency to stand trial, and the
overall influence of psychosis on criminal responsibility. As an assistant to a forensic
psychologist hired by the defense, my role focuses on preparing testimony and psychological
evidence relevant to the sentencing phase of the trial.
Mr. Davis has been diagnosed with paranoid schizophrenia and has a long history of
psychiatric hospitalization. He experiences delusions where he believes that uniformed
individuals are spies sent to kill him and suffers from both auditory and visual hallucinations
when he is unmedicated. After being arrested for trespassing, Mr. Davis spent 45 days in jail
where he was treated with antipsychotic medication. After his release from jail, he stopped using
his medication and returned to homelessness. He was then assaulted by a group of juveniles
while sleeping on a park bench. This assault appeared to trigger a psychotic break since Mr.
Davis then armed himself with a pipe and attacked two uniformed boys on their way to a Boy
Scout meeting, mistakenly believing these boys were spies that were targeting him. One boy died
from this attack, and the other was injured. Mr. Davis was arrested at the scene and later deemed
incompetent to stand trial. He was then committed to a state psychiatric facility where he
underwent treatment for eight months. After treatment, he was found competent, stood trial, and
was convicted of capital murder.
There are several key issues in this case that a forensic psychologist would need to
address. One issue is Mr. Davis’s competency to stand trial. A forensic psychologist must assess
, whether Mr. Davis had the capacity to understand the legal proceedings and assist in his own
defense. According to Dusky v. United States (1959), a defendant must have both a factual and
rational understanding of the legal proceedings. Initially, Mr. Davis was found incompetent to
stand trial and was institutionalized. However, after the eight-month treatment he underwent,
psychologists found that Mr. Davis regained his competency to stand trial. This aligns with
research indicating that antipsychotic medications can restore trial competency in individuals
with schizophrenia. (Mossman et al., 2007).
Another issue that would need to be addressed is Mr. Davis’s mental state at the time of
the offense. Mr. Davis was experiencing active psychotic symptoms at the time of the offense
that included persecutory delusions and hallucinations. The forensic psychologist must assess
whether he was incapable of recognizing the wrongfulness of his actions or if he was conforming
his behavior to the law. Bartol and Bartol (2022) emphasize that defendants suffering from
untreated schizophrenia often have diminished capacity and may meet legal criteria for insanity
or diminished responsibility depending on jurisdictional standards.
Another issue that would need to be assessed by forensic psychologists is the
implications of Mr. Davis’s psychiatric diagnosis for criminal responsibility and sentencing. The
prosecution may argue aggravating factors that include the cruel nature of the crime and the
potential for future violence. A forensic psychologist must conduct a structured risk assessment
using tools such as the Historical-Clinical-Risk Management-20 (HCR-20) to determine the
likelihood of future violence. (Douglas et al., 2014). However, it is important to differentiate
between untreated psychosis and a stable mental state under proper treatment when evaluating
risk.
