Armstrong allegedly lashed out over Wilson getting into a relationship with Armstrong's boyfriend, professional cyclist Colin Strickland. Wilson got involved with Strickland while he was briefly separated from Armstrong, his long-time girlfriend.

"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."

Armstrong's SUV, Firearm Tied to Crime Scene

Officers said they managed to identify Armstrong as the killer after they matched her 2012 Grand Cherokee to the dark-colored SUV seen on surveillance footage near the home where Strickland dropped Wilson off after they pair went for a swim and a meal, officers said in an affidavit obtained by The Austin American-Statesman.

Moreover, Officers seized Armstrong's 9mm handgun from the home she lived with Strickland. Shell casings from the firearm matched those found in the home where Wilson was slain.

A caller, who refused to be identified, contacted officers and claimed to be with Armstrong in January 2022, according to an affidavit obtained by American-Statesman. Armstrong just discovered Strickland was having a romantic relationship with Wilson even though Armstrong was dating Strickland, the individual said.

"The caller advised Armstrong became furious and was shaking in anger," police said. "Armstrong told the caller Armstrong was so angry Armstrong wanted to kill Wilson. Armstrong then proceeded to tell the caller Armstrong had either recently purchased a firearm or was going to."

According to police, Armstrong tried to keep Strickland and Wilson away from one another. Strickland told authorities he had to change Wilson's name on his phone so Armstrong wouldn't find out who he was speaking to, as he and Armstrong rekindled their romantic relationship, cops said.

They also noted that Strickland admitted he had to change Wilson's name in his phone because Armstrong had blocked Wilson's number in Strickland's phone. Strickland also had to delete text messages on his phone to prevent Armstrong from finding them."
