KANSAS CITY, MO — Jackson County prosecutors have filed first-degree murder and armed criminal action charges against a Sugar Creek man after investigators say they found a missing Independence man’s body encased in concrete during a search in May.
Charging documents identify the victim as 45-year-old Jonathan Brown and the defendant as William Morrison. Prosecutors say the case began with Brown’s disappearance and later led detectives to a residence tied to Morrison, where cadaver dogs detected the scent of human remains in a basement area near a newly poured slab.
Authorities later excavated that space and uncovered a man’s corpse. The Jackson County Medical Examiner’s office ruled the death a homicide after determining the victim appeared to have been shot once in the back of the head.
How investigators say the search led to the basement discovery
A heavily redacted probable cause document from the Jackson County Prosecutor’s Office describes a trail of information that investigators used to challenge Morrison’s explanation of Brown’s disappearance. According to the filing, Morrison told several people that Brown had gone to Springfield, Missouri.
Detectives used cellphone records and surveillance video from a nearby residence to test Morrison’s account of his movements in a white Buick sedan around the time Brown vanished. Investigators said that evidence did not match what Morrison had told others.
The same documents say one person connected Morrison to the Buick and to a house where he had been doing concrete work. That connection became important once detectives focused on the property and the fresh concrete in the basement.
Cadaver dogs alerted near a fresh slab and a dirt pile
On May 23, members of the Kansas City Fire Department and Missouri Task Force One joined the search of the residence linked to Morrison. Cadaver dog handlers and detectives were looking for signs of Brown after his disappearance raised concern among investigators.
Two independent cadaver dogs reportedly alerted to the odor of human remains in the basement. The alerts were near a freshly poured concrete slab and a dirt pile beside it, according to the probable cause document released by prosecutors.
Detectives then got a warrant to dig in that area. The excavation uncovered a body wrapped or set inside the concrete, which investigators say belonged to Brown.
Prosecutors say Morrison tried to direct attention away from himself
In addition to the search at the house, prosecutors say investigators reviewed communications involving Morrison while he was in custody on unrelated matters. The documents state that on May 23, while Morrison was in the Jackson County Jail, he contacted one of his employees and asked him to get rid of an item hidden on top of an air duct in Morrison’s home.
That item turned out to be a brown leather wallet containing an ID that alarmed the employee, who then contacted police. The filing does not say what name appeared on the identification, but it describes the discovery as significant enough to prompt a law-enforcement response.
Investigators also say a female associate of Morrison told detectives he had given her two cellphones to take to Springfield and throw away. Prosecutors say those accounts are part of the evidence linking Morrison to the case.
Morrison is already in custody and faces a parole violation warrant
Police say Morrison is currently being held on unrelated charges and also has an active felony parole violation warrant. He is on parole through the Missouri Department of Corrections for earlier convictions that include theft and involuntary manslaughter.
The new murder case adds to Morrison’s legal problems as prosecutors pursue the homicide charge tied to Brown’s disappearance and death. The Jackson County Prosecutor’s Office has not publicly said how long Brown had been missing before the body was found, but the case centers on events from May.
For investigators, the key pieces included the witness accounts, digital records, video surveillance and the unusual discovery beneath concrete in the basement of the residence associated with Morrison.
What the homicide charge means for the broader case
The filing of first-degree murder and armed criminal action charges marks a major step in a case that began as a missing-person investigation. Prosecutors say the evidence now connects Brown’s disappearance to a fatal shooting and an attempt to conceal the body.
Because the probable cause document is heavily redacted, some details remain withheld from public view. Even so, the available record shows investigators pieced together a timeline using witnesses, cellphones, surveillance and the search of the home.
Brown’s death was ruled a homicide by the medical examiner, and prosecutors say the body’s placement in concrete made the recovery especially difficult. Morrison’s case will now proceed through the court system as he faces the new charges in Jackson County.
