A Texas woman is being sought by law enforcement in connection to the shooting death of elite cyclist Anna Moriah Wilson after a love triangle turned fatal.

On Monday, the United States Marshals Service announced that it was conducting a fugitive investigation into Wilson’s shooting and that it was seeking the arrest of 34-year old Kaitlin Marie Armstrong on charges of first degree murder.

The Austin Police Department, which secured the warrant for Armstrong's arrest, suspect she was responsible for shooting Wilson to death on May 11.

The case had its beginnings in October when Armstrong had split with her boyfriend, cyclist Colin Strickland. During the interval between the break-up and renewing the relationship, Strickland briefly dated Wilson, who was visiting Austin for a race.

Upon learning about the relationship, Armstrong repeatedly expressed a desire to kill Wilson as far back as January. According to a police tipster, Strickland had purchased a 9mm Sig Sauer handgun for Armstrong, apparently unaware that the weapon would be used to kill Wilson months later.

Though Wilson and Strickland’s relationship had allegedly transitioned into a friendship by May, Armstrong continued to contact Wilson to tell her to "stay away" from Strickland.

According to the Austin police affidavit, Wilson was discovered shot to death in the bathroom of a home she was staying at in the city at approximately 9:56 p.m. and was pronounced dead at 10:10 p.m.

Detectives soon discovered surveillance footage from a nearby property that showed an SUV similar to one owned by Armstrong pull up to the home where Wilson was staying only one minute after Wilson had returned home.

They next traveled to Strickland’s home where Armstrong was staying and confronted her with the surveillance footage. According to detectives, Armstrong was informed that a vehicle resembling hers was seen at the site of the shooting and things “did not look good” for her.

Armstrong, who reportedly nodded in agreement to their assessment, was not arrested at the time, but police recovered a handgun from the home and conducted ballistic testing to see if its rounds matched the shell casings recovered at Wilson’s home. They were a match.

Strickland has not been accused of having any involvement in Wilson’s killing and his alibi was accounted for by detectives. In a statement, Strickland expressed “regret and torture” because of his “proximity” to the crime.

"Moriah and I were both leaders in this lonely, niche sport of cycling, and I admired her greatly and considered her a close friend. I am deeply grieving her loss," Strickland said in the statement.
