NBC Dateline: 5 crucial things about the murder case against Kaitlin Armstrong you need to know

1) Armstrong's relationship with Colin Strickland

Authorities believe that the motive behind murdering Wilson was romantic jealousy, making Armstrong's relationship with her boyfriend, Colin Strickland, pivotal to the case. Armstrong was involved in a long-term relationship with Strickland, a professional cyclist. As per E! News, the couple were in a live-in relationship. The pair reportedly decided to take a break from their relationship in late 2021.


2) Strickland's fling with Wilson

After Strickland and Kaitlin Armstrong broke up for a short while in late 2021, Strickland, according to E! News, got involved in a fling with Anna Moriah ''Mo'' Wilson. However, Strickland mentioned that it was a brief affair and that once he and Armstrong got back together, he was never romantically involved with Wilson.

However, he reportedly continued to stay in touch with Wilson, which he did not reveal to Armstrong. Strickland allegedly went for a swim with Wilson on May 11, the day she was murdered, but lied about where he was that day to Armstrong.


3) SUV found in security camera footage

As per E! News, the day Wilson was shot, a ''dark-colored'' SUV was shown parked next to Wilson's friend's house at 8:37 PM.

Strickland said that it's a 2012 Jeep Grand Cherokee that belonged to his girlfriend, Kaitlin Armstrong, and mentioned that he never drove it.

Subsequent investigation revealed that there was ''significant'' potential that the shell casings found by Wilson's body could have come from the Sig-Sauer that police discovered at Strickland's house. Soon, the police decided to file for Armstrong's arrest.
