The Arlington Police Department has made an arrest in connection to the murder of Kier Solomon, a transgender woman who was shot and killed at a North Arlington apartment complex in 2021.
Following a complex and thorough investigation, APD detectives obtained a warrant for the arrest of 25-year-old Arthur Morris Jr on one count of Murder. At the time of the warrant, Mr. Morris was already in the custody of the Texas Department of Criminal Justice, serving a 7-year prison sentence for an unrelated Aggravated Robbery conviction.
On September 30, 2021, at approximately 9:32 p.m., officers responded to an apartment complex in the 1100 block of Stonetrail Road after a resident reported seeing someone slumped over in a parked but running vehicle. The officers discovered the person inside the car, later identified as Ms. Solomon, had been shot. Ms. Solomon was transported to an area hospital where she was later pronounced deceased.
Detectives recovered Ms. Solomon’s phone from the car, which showed she had been messaging with an unidentified individual via an app about meeting them at the location. They determined the number used to communicate with Ms. Solomon was a temporary number that had been generated by the app.
Detectives later learned about another incident that occurred two weeks prior, where someone messaged a different victim on the same app and asked them to meet at the same location. During that encounter, the suspect took items from that victim, displayed a gun, and fired a shot at that victim’s car. Additional investigation pointed to Mr. Morris as the suspect in this incident. Given the similarities in the two cases, he became a person of interest in Ms. Solomon’s murder.
In September 2025, detectives received the break in the case they needed. Numerous search warrants related to the app account revealed an email address and ultimately a cell phone number that detectives were able to directly connect to Mr. Morris. Records for that cell phone number placed Mr. Morris at the crime scene before, during, and after the murder.
In consultation with the Tarrant County District Attorney’s Office, detectives moved forward with filing the Murder charge against Mr. Morris, as well as an Aggravated Robbery charge for the earlier incident.
“This investigation truly highlights the persistence and dedication of our detectives,” said Chief of Police Al Jones. “Sometimes we get that big break in a case right away and other times we don’t. What never changes, though, is our commitment to delivering justice for victims of crime and exhausting every possible lead to achieve that goal. I’m extremely proud of the outstanding investigate work that was done to solve this case.”
Mr. Morris is currently being held at a TDCJ facility in Childress, TX. He will be returned to Tarrant County for his arraignment.
