The investigation was therefore still broad when detectives began checking neighborhood video. That changed once the black Jeep appeared. The vehicle was not simply seen somewhere in east Austin; later electronic records put Armstrong’s Jeep beside the alley adjoining the apartment at the beginning of the critical gap and showed it moving again just after the gunshots.
THE LAST EVENING WITH STRICKLAND
Strickland’s interviews also changed as detectives learned more. When officers first delivered the news, he was not yet being confronted with every fact police possessed, and his initial estimate of when he had dropped Wilson off was imprecise. Later records allowed investigators to fix the time much more closely at about 8:36 p.m.
He described an ordinary Austin evening. He and Wilson went to Deep Eddy, then Pool Burger, and nothing about Wilson’s behavior suggested she expected someone to confront her when she returned to Cash’s apartment. Strickland did not report seeing anyone threatening her at the pool or restaurant.
What he did hide was the emotional complexity surrounding Armstrong. Strickland acknowledged that he had learned to conceal contact with Wilson because conversations about her could trigger conflict. He had deleted their message thread and saved Wilson under another contact name, behavior that initially made his own story look less straightforward than it actually was.
He also admitted sending Armstrong a false explanation after dropping Wilson off. Rather than tell Armstrong he had spent the evening with Wilson, he claimed he had been across town delivering marijuana to a friend. The lie mattered because it demonstrated that Strickland himself understood the subject of Wilson was sensitive inside his relationship.
At the same time, that lie did not make him the shooter. Location evidence placed him away from Maple Avenue during the murder window, and the Jeep data pointed back toward Armstrong’s vehicle. Investigators could therefore distinguish between deception designed to avoid a relationship argument and evidence connected directly to the homicide timeline.
Strickland also explained how the firearms entered the relationship. In December 2021, after he and Armstrong reconciled, he purchased two pistols. One was for himself, and one was for Armstrong after she expressed fears about personal safety while driving and cycling alone.
That purchase became enormously significant only after the crime laboratory compared Armstrong’s SIG Sauer P365 with the evidence from Maple Avenue. What may have begun as an ordinary self-defense purchase became one of the strongest physical links in the murder case.
ARMSTRONG AT THE POLICE STATION
The May 12 interview is important because later retellings often describe it as if detectives had already solved the murder and accidentally released Armstrong. In reality, the case was still developing, and the legal basis for holding her that day came from an unrelated misdemeanor warrant that turned out to contain the wrong birth date.
Detective Conner initially told Armstrong she was there on the theft-of-service warrant and explained that police also wanted to discuss information connected to Wilson. Because Armstrong was initially treated as being in custody, Conner began addressing Miranda warnings.
A knock on the interview-room door interrupted the process. When Conner returned, she explained that officers had learned the warrant was not valid for Armstrong because the birth date did not match. She explicitly told Armstrong she was no longer under arrest, was free to leave and did not have to continue speaking.
Armstrong immediately became cautious. She questioned whether she should have an attorney and repeatedly stated that she wanted to leave. The detective nevertheless tried to persuade her that hearing Armstrong’s side could explain facts that otherwise looked suspicious.
Armstrong said she had only learned from Strickland that a woman in the cycling community had died. She disputed the idea that she had known Strickland and Wilson were together the previous day, and she did not agree with detectives’ description of her as jealous.
Then Conner disclosed a much more serious fact: Armstrong’s Jeep had been seen near the residence. The detective told her that without an explanation, the combination of the vehicle and the relationship history looked bad. Armstrong again said she wanted to leave.
The original video narration suggests that merely mentioning a lawyer made every subsequent question illegal. The appellate court did not adopt that simplified view. The relevant issue was custody: Miranda protections apply to custodial interrogation, and after the warrant was invalidated Conner had told Armstrong she was free to leave and that the discussion was voluntary.
Armstrong later argued that statements from this encounter should have been suppressed. The Third Court of Appeals reviewed the video and circumstances in detail. It held that any error did not justify reversal because the disputed statements were largely consistent with Armstrong’s defense and because substantially stronger evidence of guilt had been introduced independently.
AFTER ARMSTRONG LEFT
Police continued building the case rather than immediately arresting Armstrong without sufficient legal support. The ballistics work, vehicle records, witness statements and digital evidence developed over the following days. On May 17, investigators had enough to secure the murder warrant.
By then Armstrong was moving quickly. She traveled from Texas to the northeastern United States and on May 18 used her sister’s passport to board a flight from Newark to Costa Rica. The use of another person’s passport became especially important because it showed more than ordinary travel; it was a method of leaving the country without traveling under her own identity.
The fugitive search lasted 43 days. Investigators eventually learned she was staying near Santa Teresa Beach, an area on Costa Rica’s Pacific coast popular with travelers and yoga communities. U.S. Marshals said local authorities located her at a hostel on June 29.
Evidence later introduced in court showed that Armstrong was using the alias Allison Paige and had undergone cosmetic procedures. Those facts became part of the prosecution’s argument that her actions after the murder demonstrated an effort to avoid identification and capture.
The defense, however, was still entitled to challenge the inference prosecutors wanted jurors to draw from flight. A defendant can dispute why she traveled, why she changed her appearance or whether post-crime conduct proves the underlying charge. The jury ultimately accepted the state’s interpretation when considered with the rest of the evidence.
THE PEOPLE LEFT BEHIND
Colin Strickland was investigated closely because he had been with Wilson immediately before her death and because he had hidden their communications from Armstrong. His location records, cooperation and the broader evidence ultimately moved investigators away from him as a suspect.
Caitlin Cash was drawn into the case simply because Wilson had been staying with her and because she was the person who opened the door that night and found her friend. Her 911 call became one of the first pieces of the public record, but her role was that of a witness and grieving friend.
For Wilson’s family, no forensic explanation or sentence could restore what was lost. The legal system could determine criminal responsibility and impose punishment, but it could not return a daughter, sister and athlete whose life had barely entered its prime.
Armstrong’s 90-year sentence remains in place. As of the Texas Third Court of Appeals decision filed January 23, 2026, the judgment of conviction had been affirmed.
The case began with a friend walking into an Austin apartment and calling 911. It ended, years later, with a record built from doorbell audio, vehicle logs, cell-phone data, a discarded bicycle, a handgun, an international fugitive search and an appellate opinion examining the investigation in minute detail.
What first looked like a baffling killing with no obvious witness eventually became a case in which technology preserved movements that the people involved could no longer explain away. For investigators, the most important witness was not a single person standing in the room that night, but the digital trail left behind by almost every step before and after the shooting.
