A required treatment filing was not submitted before a man receiving court-ordered care was accused of killing Jaquoya Wix.
DETROIT, Mich. — A fatal downtown stabbing has grown into a broader examination of Wayne County’s mental health oversight after court officials said a required treatment plan was never filed for the man now charged with killing Chipotle employee Jaquoya Wix while she was on a work break.
The disclosure does not establish that a treatment failure caused Wix’s death, and the criminal allegation against Devon Jason Watson remains unproven. But records and interviews reported by Detroit news organizations show that Watson had been ordered into psychiatric treatment months before the Sept. 20 killing and was supposed to receive continuing outpatient care after leaving a hospital. Court officials later said the provider responsible for that care failed to submit paperwork that would have allowed the probate court to monitor the treatment plan.
The sequence began in July, when a petition was filed in Wayne County Probate Court seeking psychiatric treatment for Watson after he was brought to an emergency room following a reported disturbance. Medical professionals described Watson as experiencing acute psychosis, according to court records cited by local news organizations. A judge granted the petition on July 13, authorizing hospitalization for up to 60 days along with assisted outpatient treatment after discharge. The order placed Watson within a legal system designed to combine clinical care with court supervision.
Watson was released from psychiatric hospitalization in August, according to subsequent reporting. His outpatient order called for a range of services that included case management, medication, blood testing, individual and group therapy and supervised living. The order was routed through the Detroit Wayne Integrated Health Network and then to a local treatment provider. Under the process described by court officials, the provider was required to file a treatment plan so the probate court could track the services being offered and respond if ordered care was not being followed.
Retired Wayne County Probate Judge Milton Mack, now a consultant to the court’s behavioral health unit, told WXYZ that Central City Health did not submit the required plan. Without it, he said, the court could not determine whether a treatment connection had been established or effectively monitor Watson’s outpatient care. Central City Health had not responded publicly to questions about what services Watson received. The Detroit Wayne Integrated Health Network said it was investigating the handling of Watson’s case, while officials cautioned that the review was still underway.
Against that unresolved administrative history, Wix reported for work at a downtown Chipotle on Sunday, Sept. 20. The 34-year-old mother was taking a break in an alley behind the restaurant in the 600 block of Woodward Avenue at about 2:30 p.m. when prosecutors say Watson approached her. The Wayne County Prosecutor’s Office alleges he attacked her with a knife and then fled. Prosecutors and police have said Watson and Wix did not know each other. Authorities have described the encounter as apparently random.
Nearby workers responded after Wix was wounded. Witnesses said they heard her scream and saw her attempt to reach help. Employees from surrounding businesses called 911 and tried to assist her, while another worker followed the fleeing man and relayed information to police. Emergency crews treated Wix before she was taken to a hospital, where she was pronounced dead. Detroit investigators used downtown surveillance cameras and other technology to follow the suspect’s movements, leading to Watson’s arrest near Woodward Avenue and State Street a short time later.
Wayne County Prosecutor Kym Worthy announced a first-degree premeditated murder charge against Watson on Sept. 23. Although Worthy acknowledged that the alleged attack appeared random because there was no known relationship between the two, she said prosecutors believe they can establish premeditation in court. Prosecutors have not publicly disclosed all of the evidence they say demonstrates planning. Watson was arraigned and ordered held without bond. He is presumed innocent unless and until prosecutors prove the charge beyond a reasonable doubt.
The emerging mental health history did not change the prosecution’s public position. Worthy said that the existence of mental health issues does not by itself answer whether a defendant is legally responsible for an alleged act. That question is distinct from both a clinical diagnosis and the issue of competency to stand trial. The case entered the latter process Sept. 30, when Watson’s attorney, Charles Longstreet II, asked the court to evaluate his client after citing their conversations. Judge Shawn Jacque ordered a competency examination and set a later review.
The competency evaluation concerns Watson’s present ability to understand the legal proceedings and assist his lawyer. Jacque said a review of criminal responsibility, which would focus on mental state at the time of the alleged offense, would come later if appropriate. Watson was not present at the Sept. 30 hearing, while the lawyers appeared by video. The judge scheduled a review in December. Until that process is completed, the case cannot simply be treated as a routine march toward a preliminary examination or trial.
Meanwhile, the outpatient filing issue has developed into a systemwide concern. WXYZ reported that in 2025, notices of treatment plans were filed in 453 of 1,380 mental health petitions granted in Wayne County. That means the required notices were absent in about 66% of cases reviewed by the station. The Wayne County Probate Court has since sent a letter to 21 mental health providers warning them to comply with court orders and filing requirements. Mack said providers that repeatedly fail to follow the requirements could be called before the court.
The figures suggest that the problem identified in Watson’s case was not isolated, but they do not show how many patients missed treatment, how many received services despite missing paperwork or whether any particular omission led to harmful conduct. Those distinctions matter because administrative noncompliance and clinical failure are not necessarily the same thing. Court officials have focused on the loss of oversight created when required plans are absent: without the filing, judges have less information about whether a patient has been connected with ordered services or whether further intervention might be needed.
Wix’s family has watched those institutional questions emerge while mourning a woman they describe as caring, funny and devoted to her daughter. Wix had a 15-year-old daughter and had been working at the downtown restaurant for about a year and a half, relatives said. Her family said she was proud of the job and hoped to advance. After her death, relatives established a fundraiser for funeral costs and her daughter’s future needs. A vigil brought family members, coworkers and community residents to the area outside the restaurant.
Alicya Wix, Jaquoya’s sister, later said it was difficult to learn that the monitoring system was being closely examined only after her sister had been killed. The family also thanked the nearby workers who tried to help during the attack and the people who supported them afterward. Their statements have placed a human consequence alongside what could otherwise become an abstract debate over forms, court orders and agency responsibilities: the system review arose from a case in which a mother went to work and did not return home.
The Detroit Wayne Integrated Health Network’s review remains ongoing, and the probate court has begun pressing providers for greater compliance with treatment-plan requirements. Watson’s murder case is separately awaiting the results of his competency evaluation and a court review scheduled for December. No court has found that a lapse in mental health monitoring caused Wix’s death, and Watson has not been convicted. The parallel proceedings now leave two unresolved questions: what can be proved in the homicide case and whether the treatment oversight system functioned as ordered before the killing.
