Lois Cobb’s handgun in her purse was not seized and analyzed. Arenz testifies a number of other guns belonging to RJR employees were never seized or tested.

Testifies the actual killings are not on the video. Says it could have been advisable to test Adam Fuehrer’s wallet and driver’s license, found outside Fuehrer’s body on the floor, for prints. Arenz could not say if the assailant took off his gloves at points in the video where the assailant is not seen.

He was the case agent, which means he oversaw the processing of the crime scene and delegated investigative assignments as needed. On April 1, 2019, he arrived at the RJR scene between 9:00 a.m. and 9:15 a.m. When he arrived, he saw many RJR employees outside, crime scene tape around the building and police outside as well as other BCI agents.

Arenz testifies he inventories the lunch box and released it to the employee. Learned an RJR truck driven by William and Lois Cobb was located parked at Indigo Signs. He sent two BCI agents over to the pickup to inspect and process it.

When a search warrant arrived for going through the RJR building, he and others began processing the crime scene. Arenz describes the processing the crime scene: Photography, video, type of evidence to look for and more. Explains when evidence is located, it is photographed, collected and turned over to an agent assigned as the evidence custodian. That person will package it, label it and write down key information related to the evidence. Describes the procedure to avoid cross-contamination of evidence, such as handling one piece of evidence at a time, changing gloves with each piece of evidence. Describes “chain of custody,” meaning identifying each person who handles the evidence as it goes from one person to another.

Testifies 8 or 9 agents helped him process the crime scene on April 1, 2019. Describes how he preserved the integrity of the crime scene, such as limiting access to the crime scene, wearing gloves and shoe coverings, logging all pertinent information.

Reviews the evidence inventory sheet, a three-page description of all the evidence collected on April 1, 2019, along with a chain of custody list of people who handled all the items seized.

Prosecuting attorney Karlei Neufeld

Testifies investigators do not collect and process every drop of blood at the scene. Describes the process of deciding which blood swabs to take for processing. Look for blood in locations that is not obviously from the victim or is separate or a distance from the victim. In Lois Cobb’s case, collected blood samples from door frame of bathroom, handle on the door, from the floor in the office away from Lois Cobb’s body, on the walls.

Testifies when first started processing the office shared by Robert Fakler and William Cobb, started looking for blood evidence, trace evidence (hairs, fibers), weapons, digital evidence (cellphones), identification to confirm the victim’s identity. Looking for signs of struggle. Testifies it appeared there was a struggle in the office: A fire extinguisher on the floor, a chair that was tipped over that appeared to have hit the wall and made an indentation. Says the scene suggested was a struggle between William Cobb and the assailant.

Arenz describes finding a cap in the office next to William Cobb’s head. Agents noticed a bullet hole in the side of the cap.

Arenz describes how investigators process a victim’s body at a crime scene: Photographs, evidence collection.

Arenz testifies he observed numerous stab wounds to William Cobb’s chest area, injuries to his arms and an injury to the left side of his head. At the scene, says investigators located what appeared to be bullet wounds in both forearms and the head. Says when the coroner was later moving the body, a bullet fell from an arm. That bullet was retrieved and saved as evidence and tested.

Then Arenz processed the scene around Lois Cobb’s body in the office. Says there were bloodstains inside and outside the bathroom. She had deep lacerations to the neck, stab wounds to the chest, a gunshot wound to the chest and a wound on one of her arms. Says it appeared the attack on her started outside the bathroom and ended with her partially inside the bathroom, based on bloodstains, her eyeglasses lying next to her outside the bathroom and the position of the body (upper portion of her body in the bathroom and lower portion outside the bathroom).

When the coroner later moved the body, they discovered additional stab wounds on Lois Cobb’s back.

8:43 a.m.: The jury is being brought into the courtroom.
