Prosecutors charged Antwon Shirley after Nevada Mosley was fatally shot inside her home, where three juveniles were present.

KANSAS CITY, Mo. — Three children inside a Kansas City home became some of the most important witnesses in the investigation of their mother’s fatal shooting after police say one child saw her boyfriend point a gun at her and heard gunfire moments later.

Antwon Shirley, 43, was charged in Jackson County with second-degree murder, armed criminal action, first-degree burglary, unlawful possession of a firearm and two counts of endangering the welfare of a child in the Aug. 1 death of 38-year-old Nevada N. Mosley. The Jackson County Prosecutor’s Office publicly listed the charges in an Aug. 7 case update and emphasized that they are accusations. Shirley is presumed innocent unless he pleads guilty or is convicted.

The investigation began shortly before 7 a.m. Aug. 1, when Kansas City police were dispatched to a residence in the 5600 block of Agnes Avenue after a report of a shooting. Officers arriving at the home encountered a juvenile outside and found the front door open, according to court-document accounts reported by local news organizations. Inside the house, officers found Mosley in a back bedroom suffering from gunshot wounds. She was taken to a hospital, where she was pronounced dead.

Three juveniles were in the residence, and investigators quickly began relying on what they said and what officers found in the bedroom. According to the probable cause account, one child was awake during the shooting. Police said the child described hearing a clicking sound shortly before seeing Shirley point a firearm at Mosley. The child told investigators that Mosley tried to get out of bed, struck an adjacent dresser and that gunshots followed. The child then left the bedroom to seek a relative. Two other children had been asleep when the confrontation began, authorities said.

The children’s presence is reflected directly in the criminal case. In addition to the homicide, burglary, weapons and armed criminal action counts, prosecutors charged Shirley with two counts of endangering the welfare of a child. Authorities have not publicly released the children’s names, and the available charging accounts do not provide their ages. Their identities are being withheld in this report because they are minors and because further identifying information is not necessary to describe the case.

Investigators also documented physical and circumstantial evidence inside and outside the home. Police said the bedroom door appeared to have been kicked in. Shell casings were recovered from the bedroom floor, along with paperwork associated with Mosley and Shirley. Surveillance footage also showed a vehicle belonging to Shirley outside the residence, according to the probable cause statement as described in published reports. Those details became part of the evidence police cited while identifying Shirley as the suspect.

The shooting followed signs of conflict in Mosley and Shirley’s relationship, according to witnesses interviewed by investigators. One witness said the pair had not been getting along and described Shirley as jealous. That witness also said Mosley had wanted Shirley to return the keys to her home. A separate account in court-document reporting said Shirley had taken Mosley’s cellphone on July 30 before returning the phone and her house keys later that night. The same account said he came back in the early morning hours and asked to be allowed inside.

Those statements provide investigators with a timeline of tension before Mosley’s death, but they remain witness accounts rather than judicial findings. Prosecutors have not established at trial what led to the shooting, and no available court ruling has determined Shirley’s motive. The second-degree murder charge alleges criminal responsibility for Mosley’s death, while the burglary charge concerns his alleged entry into the residence. The precise factual and legal theories prosecutors intend to prove would be tested through the court process.

Police said Shirley was no longer at the house when officers responded. Investigators later received information from one of his relatives, who said Shirley contacted her after the shooting. According to the probable cause statement, Shirley allegedly told the relative that he had done something bad and that he had “snapped” and shot Mosley. Authorities also said Shirley told more than one person that he intended to surrender because he believed police throughout the city would be looking for him.

Before that surrender, however, investigators believe Shirley took steps that made him more difficult to locate. Police alleged that he disposed of his cellphone and got rid of a vehicle registered to him. Those actions are described in the investigative record as part of what occurred after the shooting. They do not, by themselves, resolve the murder allegation, and the available reports do not establish whether prosecutors have filed any separate charge specifically tied to disposal of the phone or vehicle.

Shirley surrendered to Kansas City police on Aug. 2, the day after Mosley was shot. Published accounts said he turned himself in at the Kansas City Police Department’s East Patrol Division. A judge ordered him held on a $500,000 cash-only bond. The prosecutor’s office subsequently identified him in its weekly report of newly filed cases, listing the murder count together with armed criminal action, burglary, unlawful possession of a firearm and the child-endangerment counts.

The case brings unusual importance to the accounts of children who were inside the home. One child’s description placed Shirley and Mosley together immediately before the gunfire, according to police, while the juveniles’ presence also formed the basis for separate criminal charges. At the same time, the probable cause statement represents an early stage of the criminal process. Statements collected by investigators can later be challenged, supplemented or tested in court, and prosecutors carry the burden of proving each charge beyond a reasonable doubt if the case reaches trial.

Public reporting available shortly after Shirley’s arrest listed a preliminary hearing for Sept. 2. That date has since passed, but reliable public sources reviewed for this report did not establish the outcome of that hearing or identify a later trial date. The prosecutor’s office has continued to list the filed allegations as criminal charges, and no reviewed source established that Shirley has been convicted in Mosley’s death.

Mosley’s death left investigators with several different categories of evidence: a child’s eyewitness account, statements from other people in the home or connected to the couple, surveillance footage, evidence recovered from the bedroom and statements Shirley allegedly made after leaving the scene. How much of that evidence is admitted and what weight it receives will depend on future court proceedings. For now, the case remains one in which the people closest to the violence included children who police say were inside their mother’s home when she was killed.
