The arrest warrant from Austin police says Kaitlin Marie Armstrong was dating Colin Strickland, another star cyclist. Wilson had also been romantically involved with Strickland, according to police. Surveillance videos and ballistics appear to connect Armstrong to Wilson's murder.
On May 11, 2022, at approximately 9:56 PM, APD Officer Martin Salinas #9382 responded to a check welfare urgent call at 1708 Maple Avenue in Austin, Travis County, Texas. Officer Salinas arrived on scene and located the caller inside of the residence performing CPR on a female subject, later identified as Anna Wilson. Officers on scene reported Wilson had multiple defects on her body that had the appearance of gunshot wounds.
Wilson's friend advised she went inside of her residence approximately two minutes before she called 9-1-1 and noticed the front door to the residence was unlocked. Wilson's friend stated Wilson was observed lying on the bathroom floor covered in blood and no one else was inside. Wilson's friend advised Wilson's Specialized S-Works bicycle appeared to be stolen but nothing else inside was missing.
Detective Rolando Ramirez #4140 observed a surveillance camera mounted on the exterior of a residence near the crime scene. This residence is directly north of Wilson's friend's residence and the camera faces a driveway next to Wilson's friend's residence. Strickland advised he currently lives with his girlfriend, Kaitlin Armstrong, a white female, born on April 21, 1987. Strickland stated they have been dating for approximately three years but briefly ended their relationship for one to two weeks in October 2021. Wilson and Strickland then had a romantic relationship before Strickland ultimately began dating Armstrong again.
Strickland advised he did not go inside of the residence and left promptly after dropping off Wilson. Strickland advised he drove his motorcycle northbound through an alleyway until East Martin Luther King Jr. Boulevard. Strickland advised he stopped his motorcycle and sent a text message from his phone to Armstrong at 8:36 PM.
Strickland went into the garage and began working on his bicycles to prepare for an upcoming race. While in the garage, Strickland sent another text message to Armstrong at 9:21 PM. Strickland advised not long after he sent that message, Armstrong arrived to the residence driving the 2012 Jeep Grand Cherokee with the large bicycle rack mounted on the trailer hitch of the vehicle, a luggage rack mounted on the roof, and chrome around the windows.
