Arlington Police Arrest Suspect in 2021 Murder of Kier Solomon

UPDATE: Arlington Police have made a significant breakthrough in the 2021 murder of transgender woman Kier Solomon, arresting 25-year-old Arthur Morris Jr. today. This arrest comes after a relentless four-year investigation, with Morris currently serving time for unrelated charges in the Texas Department of Criminal Justice.

On September 30, 2021, officers discovered Solomon shot in her car at a North Arlington apartment complex. Despite immediate medical attention, she tragically succumbed to her injuries. Detectives quickly identified a disturbing pattern: Solomon was lured to the location via a dating app, a tactic also linked to Morris in subsequent investigations.

The investigation gained momentum when another victim reported a similar incident involving robbery and aggravated assault just weeks prior to Solomon’s murder. Authorities noted that this modus operandi raised red flags and led them to focus on Morris.

By September 2025, detectives had pieced together crucial evidence connecting Morris to the crime scene through phone and email records, placing him “before, during, and after the murder,” according to the Arlington Police Department. Police Chief Al Jones praised the investigative team’s persistence, stating,

“What never changes, though, is our commitment to delivering justice for victims of crime and exhausting every possible lead to achieve that goal.”

Currently held in a facility in Childress, Texas, Morris awaits transfer to Tarrant County for his arraignment. The arrest marks a pivotal moment for Solomon’s family and the community impacted by her violent loss. The tireless work of Arlington detectives demonstrates a commitment to justice, offering a glimmer of hope for the loved ones left behind.

As this story develops, the Arlington Police continue to encourage anyone with additional information to come forward. The community watches closely as justice inches closer for Kier Solomon.
