The rapid arrest in Jaquoya Wix’s killing was followed by a murder charge, a competency review and questions about earlier court-ordered treatment.
DETROIT, Mich. — Within minutes of the fatal attack on restaurant worker Jaquoya Wix, witnesses were calling for help, a nearby employee was following the fleeing man and Detroit police were turning to the downtown camera network that would help them locate a suspect a short distance away.
The fast arrest did not resolve the harder questions that followed the Sept. 20 killing. Authorities say Wix, 34, and the man accused of attacking her did not know one another, leaving investigators with no publicly established personal connection to explain the violence. Prosecutors have nevertheless charged Devon Jason Watson, 42, with first-degree premeditated murder. Since then, his prior mental health treatment has become a subject of public scrutiny, and a judge has ordered a competency evaluation that has slowed the criminal case.
Police said the emergency began at about 2:30 p.m. in an alley near Woodward Avenue and East Congress Street, in the center of downtown Detroit. Wix was working at a Chipotle and had gone outside for a break. Prosecutors allege Watson approached her as she sat in the alley and attacked her with a knife. There was little interaction between the two before the attack, investigators said in the initial days of the case. City officials described the assault as unprovoked.
The activity around the alley quickly drew the attention of employees at neighboring businesses. Witnesses told local reporters they heard Wix scream. Workers came through a nearby back door and tried to help her while someone called 911. Another employee saw the man police were seeking and followed him while communicating with authorities. That combination of witnesses on the ground and cameras positioned around downtown gave officers information about the suspect’s direction of travel after he left the scene.
Police then used surveillance cameras and other technology to trace the man toward the area of Woodward Avenue and State Street. Watson was taken into custody about 20 minutes after the attack, according to police accounts reported by local news organizations. Investigators later said they believed they had recovered the knife used in the killing and were processing it as evidence. The arrest ended the immediate search but opened a homicide investigation that would soon involve prosecutors, court records and questions reaching beyond the events in the alley.
Wix was taken to a hospital after receiving emergency care but was pronounced dead. Her death immediately changed what had begun as a workday for employees along one of Detroit’s busiest downtown corridors. Wix had a 15-year-old daughter and had worked at the restaurant for about a year and a half, according to her relatives. Family members described her as funny, talkative and caring. They said she was proud of her job and believed she might have an opportunity to move into management.
The public setting of the killing contributed to the shock expressed by people downtown in the hours afterward. Residents interviewed by local news outlets said they were unsettled that a worker could be attacked during the daytime while taking a break from her job. Detroit Police Chief Todd Bettison later said officers would increase attention to alleys and other places where people might be more vulnerable. Those steps were announced as city leaders sought to reassure the public without suggesting that the killing reflected a known dispute or an identified broader threat.
On Sept. 23, Wayne County Prosecutor Kym Worthy charged Watson with first-degree premeditated murder. The prosecutor said Watson and Wix did not know each other and that the alleged conduct appeared random. At the same time, Worthy said her office believed it could prove premeditation beyond a reasonable doubt. The two descriptions are not legally incompatible: an alleged victim may be chosen without a prior relationship while prosecutors still contend that the accused formed an intent to kill and acted after deliberation. The evidence supporting that theory has not been fully presented in public court proceedings.
Watson was arraigned and ordered held without bond. The charge is an allegation, and he is presumed innocent unless convicted. The case later shifted from the factual question of what occurred in the alley to a procedural question about whether Watson is presently able to participate in his defense. His lawyer, Charles Longstreet II, requested a competency examination at a Sept. 30 hearing after citing his communications with Watson. Judge Shawn Jacque granted the request and scheduled a review for December.
Competency is separate from criminal responsibility. The evaluation ordered by Jacque is intended to address whether Watson can understand the proceedings and assist his attorney now. The judge said a review of Watson’s criminal responsibility at the time of the alleged killing would be considered later in the legal process. That distinction became especially important because officials and reporters had uncovered records showing that Watson had been the subject of a mental health proceeding only months before Wix was killed.
According to court records cited by Detroit news organizations, a petition was filed in July after Watson was brought to an emergency room and medical professionals concluded he was experiencing acute psychosis. A judge authorized psychiatric hospitalization followed by assisted outpatient treatment. Watson was later released from the hospital in August. The outpatient order called for continuing services, but court officials said the treatment provider did not file a required plan describing how that care would be carried out.
The missing filing attracted attention because it was supposed to give the probate court information needed to monitor whether services had been arranged. Retired Wayne County Probate Judge Milton Mack, a consultant to the court’s behavioral health unit, said the absence of the plan made it difficult for the court to track Watson’s care. The Detroit Wayne Integrated Health Network said it would investigate the handling of the case. No finding has established that the missing filing or any treatment issue caused the later killing, and the provider had not publicly detailed the services Watson received.
Further reporting suggested the paperwork problem was broader than a single defendant. WXYZ reported that treatment-plan notices were filed in only 453 of 1,380 granted Wayne County mental health petitions in 2025. The probate court subsequently contacted 21 providers and directed them to comply with filing requirements. The disclosure transformed a case that initially raised questions about downtown public safety and rapid police response into one that also involves the reliability of a court-supervised mental health system.
While those institutions examine their procedures, Wix’s relatives have focused on the person behind the case file. A candlelight vigil brought people to Woodward Avenue and the alley where she was attacked. Her sister, Alicya Wix, thanked the strangers and nearby workers who tried to help. Relatives said Wix cared deeply about her daughter and was trying to improve her circumstances. A family fundraiser was established to assist with funeral costs and the teenager’s future needs. Chipotle also expressed condolences and said it was cooperating with law enforcement.
The investigation produced a swift arrest, but the case itself is now moving more slowly through the safeguards of the court system. Watson remains charged with first-degree murder and is presumed innocent. His competency evaluation must be addressed before the prosecution advances through its next stages, while a separate review continues into the outpatient-treatment system that had handled his earlier case. The publicly known evidence has established neither a motive for the alleged attack nor a final explanation for why Wix, on a routine break from work, became its victim.
