In the ongoing trial of Kaitlin Armstrong for the murder of Anna Moriah “Mo” Wilson, testimony concluded Monday with firearms forensics examiner Steven Aston discussing the bullets recovered from the crime scene in east Austin. Aston’s testimony on Tuesday focused on the unbiased nature of ballistic examinations. He identified the projectiles found at the scene – two bullets in different conditions and a set of bullet fragments – as originating from the gun police allege Armstrong used in the shooting.

The trial, which began about two weeks ago, has included testimony from various witnesses. These include Wilson’s brother, her friend Caitlin Cash who discovered Wilson and called 911, crime scene analysts, Austin Police Department homicide detectives, neighbors, Armstrong’s former boyfriend Colin Strickland, Armstrong’s friends, and a U.S. Deputy Marshal who apprehended Armstrong in Costa Rica approximately a month after the murder. Testimony also came from the owner of a gun range Armstrong visited months before the murder.

The defense argues that despite surveillance footage showing Armstrong’s Jeep at the crime scene, there is no video evidence of Armstrong herself at the location. Armstrong was captured on airport surveillance video before fleeing to Costa Rica, where she was later arrested and extradited to Texas.

Dr. Bernadette Derussy, who performed the autopsy on Wilson, testified about the nature of the gunshot wounds. Wilson suffered two headshots and one to the heart, consistent with previous testimonies. A wound on Wilson’s index finger and a graze wound on her leg were also noted, with the finger wound potentially indicating a defensive action.

Officer Rosalda Johnson, involved in transporting Armstrong for a medical appointment, testified about Armstrong’s brief escape attempt on October 11, 2022, which led to a chase before Armstrong was apprehended.

DNA specialists Alejandra Gil and Samantha Perkins from the DPS crime lab testified regarding DNA evidence. Gil prepared DNA samples from Wilson’s bicycle, Armstrong’s firearm, and saliva samples from various individuals. Perkins’ analysis revealed Armstrong’s DNA on both Wilson’s bicycle, found near the murder scene, and the firearm. Strickland’s DNA was also present on the firearm, but less prominently than Armstrong’s.
