This case against a Kansas City man is built around the evidence points that repeat across the police narrative, witness statements, and the defendant’s interview.
KANSAS CITY, Mo. — The early case against Demario McGee in the killing of Katrice Williams is built less on one single public piece of evidence than on several accounts that line up in key places: an argument outside a house, gunfire near a parked SUV and McGee’s own statement to detectives.
Prosecutors charged McGee, 37, with second-degree murder, two counts of armed criminal action and unlawful use of a weapon after Williams, 32, was found fatally shot in a backyard on East 62nd Street. The case matters at this stage because the released documents already show how investigators are likely to argue reliability: they have witness reports about the sounds and movement around the shooting, a statement from McGee acknowledging he fired a gun to scare Williams and a scene that placed her beside the vehicle where the couple had been staying.
The points of overlap begin before the shooting. McGee told police he and Williams went to the residence so he could record music in a basement studio. Witnesses also placed him at the house for that purpose. He told detectives Williams stayed in the gold Chevrolet Traverse while he went inside, and the police account says officers later found her outside that same vehicle. He said he had gone out repeatedly to talk with her and to ask her to come in so they might be able to sleep there for the night. Witnesses, meanwhile, reported hearing a man and woman arguing outside. Those details matter because they tie the defendant, the victim, the location and the dispute together before the first shot was reported.
The next overlap comes around the gunfire itself. Witnesses inside the residence told police they heard three shots. A woman said she heard an argument followed by gunshots. A man said he also heard arguing and shots before seeing a male in a light-colored hoodie moving toward the back of the property. McGee, in his interview, admitted to handling the firearm during the confrontation. According to the probable cause statement, he said he started shooting into the air to scare Williams and that the gun might have gone off as he raised it. Prosecutors are not adopting his phrasing. They charged him with murder and with exhibiting a 9 mm firearm in an angry or threatening manner, signaling that they see the weapon use as criminal conduct before and during the fatal shot, not as a neutral attempt to frighten someone away.
The final overlap appears in what happened immediately afterward. Witnesses told police they saw McGee move away from the area after the shots and then return. McGee told detectives that after the shooting he ran two or three houses east and threw the firearm. Officers who responded just after 3 a.m. found Williams with gunshot wounds to the neck in the backyard and found McGee there acting erratically, according to the records. Witnesses also described a change in his behavior, saying he appeared calm when they first came out and later became erratic and yelled that someone had shot his girlfriend. Investigators can be expected to use those overlapping descriptions of movement and behavior to argue consciousness of guilt, though a defense lawyer may later attack the timing, the stress level of the witnesses and the meaning of McGee’s statements.
What the evidence file does not yet show is also important. The public documents do not say whether the gun has been recovered after McGee allegedly threw it away, whether forensic testing has matched any shells or bullets to a specific weapon, or whether nearby cameras captured the yard, the street or McGee’s movement after the shots. There is also no public indication yet of whether the defense will dispute the voluntariness or wording of McGee’s statement after Miranda warnings. Those unknowns do not erase the overlap already in the record, but they mark the likely points where the case could shift as it moves beyond the probable cause phase and into fuller litigation.
Jackson County Prosecutor Melesa Johnson announced the charges on March 23, one day after the shooting. A judge set McGee’s bond at $250,000 cash only, and the prosecutor’s office noted that the charges are accusations and that he remains presumed innocent unless convicted or unless he pleads guilty. For now, the prosecution’s public theory is plain: Williams died during an argument outside the house, and the pieces released so far fit together closely enough for the state to proceed on a homicide charge. Whether that alignment holds under cross-examination and forensic review will shape every step that comes next.
For now, the state’s case remained centered on those repeated points of agreement across witness statements, scene details and McGee’s interview, with the next court milestone expected to test how durable that alignment is.
