‘Deleted mystery note’: Detective Testifies on Accused Killer Kaitlin Armstrong’s Note Found in Phone

The murder trial for Kaitlin Armstrong continued Wednesday in Austin, with a police detective testifying that the accused killer deleted a note shortly after the death of Moriah “Mo” Wilson.

Austin Police Detective Richard Spitler testified Wednesday morning that over two dozen search warrants were executed during the homicide investigation, including searches on Armstrong’s iCloud account. According to Spitler, Armstrong deleted a note with an address near the apartment complex crime scene the day after the murder.

The note, according to Spitler, had the address, 1704 Maple Avenue, saved. The murder happened at 1708 Maple Avenue in Austin.

As CrimeOnline previously reported, Armstrong, who’s currently on trial for allegedly murdering Wilson, was arrested in 2022, in a Costa Rica hideaway spot she fled to after Wilson’s death. Investigators believe that the defendant murdered Wilson after Wilson was having an affair with, Colin Strickland, identified as Armstrong’s then-boyfriend.

Police found Wilson, a professional cyclist who arrived in Austin for a race, deceased inside her friend Caitlin Cash’s apartment in May 2022. She had been shot multiple times, police said, after going out to dinner and swimming with Strickland.

Spitler added Wednesday during testimony that Armstrong apparently kept tabs on the manhunt for her, following Wilson’s death, according to her phone data.

Armstrong managed to remain elusive for 45 days after the murder. Investigators said she sold her Jeep before fleeing, and then used her sister’s passport and spent thousands getting plastic surgery in an attempt to alter her appearance.

“Everything about this scene… seemed like it was very personal,” Spitler said.

According to testimony, other evidence found in Armstrong’s phone included:

  • Flight reservations from New Jersey to Costa Rica
  • An Uber receipt showing a ride from Armstrong’s residence to the Austin-Bergstrom International Airport
  • Internet searches for news coverage concerning “Kaitlin Armstrong”
  • Skype and VPN purchases
  • Southwest Airlines itinerary email

Armstrong pleaded not guilty. If convicted, she could face up to 99 years in prison.
