Texas officials are asking for the public’s assistance in their search for a woman accused of killing a professional cyclist.

Per a regional report from KXAN-TV, an arrest warrant was previously issued for Kaitlin Marie Armstrong in connection with the death of cyclist Anna Moriah Wilson. Armstrong, according to an arrest affidavit cited in the report, has been accused of first-degree murder.

In a statement shared earlier this month, the Austin Police Department said officers had responded on May 11 just before 10 p.m. local time to an emergency call from a woman who said she had “returned home to find her friend bleeding and unconscious.” The victim, later identified as Wilson, was pronounced dead that same evening.

At the time, police said an initial investigation showed Wilson had been shot inside the home. An official cause of death said she died due to multiple gunshot wounds. The U.S. Marshals Lone Star Fugitive Task Force has since confirmed it is also assisting in the investigation after receiving a request from the Austin Police Department.

“Members of the Lone Star Fugitive Task Force are actively conducting a fugitive investigation and pursuing leads on the whereabouts of Armstrong,” the agency said in a statement dated May 20.

Armstrong has reportedly removed her social media accounts and was said in an arrest affidavit to have “not been seen or heard from” since May 13. Subsequent days have seen additional alleged details surrounding the investigation being made public, including word that Armstrong—according to a friend cited in the KXAN-obtained affidavit—had learned in January that a man with whom she was in a romantic relationship (Colin Strickland) had also been in an alleged relationship with Wilson.

The friend, who is not named in reports, is said to have told police they recalled Armstrong becoming “so angry [she] wanted to kill Wilson.”

On the day officers responded to the aforementioned emergency call, Strickland allegedly dropped Wilson off at the residence (which belonged to a friend of the cyclist) around 8:35 p.m. local time. Security footage obtained from a neighbor is alleged to show Armstrong’s vehicle arriving at the residence shortly after.

A GoFundMe page has been launched by the family of Anna Moriah Wilson, who also went by “Mo.” According to the fundraiser’s description, donated funds will be put toward “community organizations that help youth find self-confidence, strength, and joy through biking, skiing, and other activities that Moriah was passionate about.”
