Antwon Shirley made incriminating statements to relatives before surrendering one day after Nevada Mosley was fatally shot, investigators say.
KANSAS CITY, Mo. — A man accused of killing his girlfriend inside her Kansas City home allegedly told people he expected the entire city to be looking for him, disposed of his cellphone and separated himself from his vehicle before surrendering to police the next day, according to investigators.
Antwon Shirley, 43, turned himself in Aug. 2 after police identified him as the suspect in the fatal shooting of Nevada N. Mosley, 38. Prosecutors later charged him 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. A judge set his bond at $500,000 cash only.
The surrender ended roughly a day in which investigators say Shirley had left the scene, communicated with people who knew him and considered giving himself up while taking actions police interpreted as efforts to conceal his location. According to the probable cause account, one of Shirley’s relatives contacted law enforcement after speaking with him. The relative said Shirley acknowledged that he had done something bad and allegedly said he had “snapped” and shot Mosley.
Investigators said Shirley spoke on two occasions to two different people about surrendering. In one of those conversations, police said, he suggested that “the whole city” would be looking for him. Authorities allege that before turning himself in, Shirley disposed of his cellphone and got rid of a vehicle registered in his name. Public reports do not explain precisely what became of either item or whether investigators recovered them.
Shirley ultimately surrendered at the Kansas City Police Department’s East Patrol Division, according to local reporting. His decision to turn himself in became the final step in an investigation that began the previous morning at a home on Agnes Avenue, where officers found Mosley critically injured and children still at the residence.
Police had been dispatched to the home shortly before 7 a.m. Aug. 1. An arriving officer encountered a juvenile outside the residence, and the front door was open, according to court-document accounts. Officers entered and located Mosley in a back bedroom with gunshot wounds. She was transported for emergency treatment but was pronounced dead at the hospital.
By the time police were looking for Shirley, detectives had multiple reasons to focus on him. Three juveniles were at the home, and authorities said their statements identified Shirley in connection with the violence. One child who was awake reportedly heard a clicking sound and saw Shirley point a firearm at Mosley. Police said the child described Mosley trying to get out of bed, striking a nearby dresser and then hearing multiple shots before fleeing the room to find a relative.
The bedroom itself provided another line of evidence. Investigators said its door appeared to have been kicked in. Shell casings were on the floor, and police also found paperwork belonging to Mosley and Shirley. Surveillance video showed Shirley’s vehicle outside the residence, according to the probable cause statement. The combination of witness information and physical evidence meant police were not relying solely on the statements Shirley allegedly made after leaving.
Investigators were also told about conflict between Shirley and Mosley before the shooting. One witness said the couple had not been getting along and described Shirley as jealous. Police said Mosley had requested the return of her house keys. Another account said Shirley had taken Mosley’s cellphone on July 30 before giving it and the keys back that night. He later returned to the house in the early morning hours and asked to be let inside, according to the witness statement described in court reporting.
Those earlier events form part of the prosecution narrative, but they have not been established as findings of fact at trial. Similarly, Shirley’s alleged remarks to relatives are attributed statements contained in the investigation. A defendant can challenge how statements were obtained, what was actually said, how witnesses understood them and whether the statements are admissible. No public material reviewed for this report establishes that a judge or jury has ruled on those questions.
The Jackson County Prosecutor’s Office publicly confirmed Shirley’s charges in its Aug. 7 weekly case update. The office listed him among defendants facing newly filed cases and specifically cautioned that charges are accusations. Shirley therefore remains legally presumed innocent unless he enters a guilty plea or prosecutors prove the allegations against him in court.
The murder charge is only one part of the case. Prosecutors also allege first-degree burglary, a count that corresponds with the circumstances of Shirley’s alleged presence in Mosley’s home. The armed criminal action count is tied to the alleged use of a weapon in another felony. An unlawful-possession count concerns Shirley’s alleged ability to legally possess the firearm. Two child-endangerment allegations reflect the presence of juveniles during the incident.
Authorities have not publicly identified the children in the reports reviewed for this article, and their names are not necessary to understand the criminal case. Police said three juveniles were in the home, though two were asleep when the confrontation began. The account attributed to the child who was awake could become especially important because it describes the moments directly preceding the gunfire.
The actions police attribute to Shirley after the shooting may also receive scrutiny as the case proceeds. Investigators often document a suspect’s movements, communications and behavior after an alleged offense, but the meaning of those actions is ultimately a matter for the legal process. The allegation that Shirley discarded a phone and disposed of a vehicle does not itself establish that he committed murder. Prosecutors would have to connect any such evidence to the crimes charged and meet the required burden of proof.
Published reports at the time of Shirley’s arrest stated that a preliminary hearing was scheduled for Sept. 2. That date is now past. The reliable public sources reviewed for this report do not establish the result of that proceeding or provide a verified later trial date, so the initial hearing schedule cannot be described as a future event.
The publicly documented case therefore ends, for now, not with a verdict but with the surrender that followed Mosley’s death. Police say Shirley left the Agnes Avenue home, made statements to people he knew, took steps to distance himself from a phone and vehicle and then walked into a police facility the next day. Prosecutors must still prove what happened before that surrender, including who fired the shots that killed Mosley and whether each of the six charged offenses can be established beyond a reasonable doubt.
