The body of Anna Moriah “Mo” Wilson, 25, of San Francisco, was found May 11, and Austin police issued a murder warrant for Kaitlin Marie Armstrong, 34, last week.
The warrant affidavit says there was a possible romantic triangle involving Armstrong, Wilson and Colin Strickland, another professional cyclist who had been Armstrong’s longtime boyfriend.
The affidavit says Strickland took up with Wilson after he and Armstrong split last October but that Strickland and Armstrong had subsequently reconciled.
Strickland has cooperated with investigators and is not a suspect.
Wilson was in Austin for a race in Hico, which is about 190km north.
Within 24 hours of Wilson’s death, officers from the Lone Star Fugitive Task Force apprehended Armstrong in connection with an unrelated arrest warrant and spoke to her.
However, Austin police then said they learned Armstrong’s arrest warrant was not valid and told her she was free to leave.
Armstrong requested to end the interview and left after detectives began confronting her about security camera video that allegedly placed her car near the crime scene, an affidavit states.
