Kaitlin Armstrong: Never before seen evidence from murder trial

AUSTIN, Texas - FOX 7 has obtained evidence from the Kaitlin Armstrong murder trial. It has never been seen outside the courtroom. 

Armstrong was sentenced to 90 years in prison for the murder of her boyfriend’s friend, Anna Moriah Wilson.

Screams and three gunshots are heard on a neighbor's surveillance camera.

"My friend is staying with me and I just walked in, and she’s lying on the bathroom floor and there’s blood everywhere and I don’t know what happened," Anna Moriah Wilson’s friend, Caitlin Cash said to dispatch after calling 911.

Cash walked into a murder scene. Her friend, Wilson, was lying on the ground and not breathing.

"Just pump hard and fast and count out loud so I can count with you," the dispatch told Cash on the phone.

"1, 2, 3, 4, 5, 6," Cash is heard on the phone.

Cash performed CPR for more than five minutes until EMS and police arrived.

Wilson had been shot multiple times.

Wilson was visiting from California and staying in Cash’s East Austin home. Wilson was a professional cyclist, preparing for an upcoming race nearby.

Earlier in the day, Wilson reconnected with a fellow professional cyclist.

"She was with our friend, Colin, Colin Strickland," Cash told Austin Police investigators.

"She went swimming, I left to go have dinner with my friends, and then I came back, and this is my house, this is my house, and she’s staying with me," Cash told investigators.

Cash told Austin police one item was missing, Wilson’s bike.

"Where would she keep her bike?" an Austin police officer asked Cash.

"I mean it would be right inside the door," Cash said.

While a detective was taping off the area, she found something in the bushes.

"Hey, come here, somebody might be in here, this might be the bike," an Austin police investigator said.

At this point, they didn’t know how the bike got there or who was responsible for moving it.

How Kaitlin Armstrong became connected to this evidence is what detectives determined in the next few days before she fled the country.
