(AUSTIN) -- U.S. Marshals found the black Jeep Grand Cherokee registered to Kaitlin Marie Armstrong, the Austin woman suspected of killing professional cyclist Anna Moriah Wilson in May, the law enforcement agency said Thursday.
Investigators with the U.S. Marshals Lone Star Fugitive Task Force discovered that Armstrong sold the car to a CarMax dealership in Austin on May 13 for $12,200. Armstrong received a check from CarMax just one day after she was questioned by police, they said.
Wilson was found bleeding and unconscious at a friend's house on May 11 after suffering multiple gunshot wounds, according to police. Despite first-responders performing life-saving measures, she was pronounced dead. Police issued a warrant for Armstrong's arrest and have been looking for her since last month. She faces a first-degree murder charge.
Colin Strickland, who has been dating and living with Armstrong for three years, dated Wilson during a brief break in their relationship. Strickland and Armstrong resumed dating after that. The day Wilson was killed, she had met with Strickland to go swimming, according to police.
Investigators said Armstrong went to Austin International Bergstrom Airport on May 14, where she boarded a flight to Houston Hobby Airport. Shen then took a connecting flight to New York LaGuardia Airport. Her last known location is the Newark Liberty International Airport where she was dropped off on May 18, according to U.S. Marshals.
Investigators say a source told them Armstrong was provided with transportation to the Newark airport on May 18, but upon searching outbound flights from the airport they found no flight reservations under her name.
The U.S. Marshals Service has elevated the case to "major" and is offering a reward of up to $5,000 in addition to the $1,000 reward from the Capital Area Crime Stoppers, for any information that leads to her arrest. An anonymous donor is also offering up to $15,000 in reward money for her arrest, according to the agency.
Investigators put out a warrant out for Armstrong's arrest on May 25 for unlawful flight to avoid prosecution.
U.S. Marshals described Armstrong as 5 feet, 8 inches tall and weighs about 125 pounds. She has long, curly light brown hair and hazel eyes.
