(Newser) – Kaitlin Marie Armstrong told the elite cyclist she is accused of killing to "stay away" from her boyfriend, according to documents revealing what authorities say is increasing evidence against the 34-year-old who's been on the lam for more than a month. After being confronted on May 12 with video evidence showing a Jeep Grand Cherokee like the one she owned driving up to the Austin home where Anna Moriah "Mo" Wilson was shot dead the day prior, Armstrong almost immediately sold the vehicle then fled the state of Texas, according to US Marshals. She flew out of Austin on May 14, three days before a murder warrant was issued, and was tracked to New Jersey's Newark Airport on May 18 but no further, per NBC News.
