A jury found Brian Steven Smith guilty of the murders of Kathleen Jo Henry, 30, and Veronica Abouchuk, 52, two Alaska Native women who died on September 4, 2019 and August 2018, respectively.

Smith was found guilty of all 14 criminal charges, including first- and second-degree murder, tampering with evidence and sexual assault in the deaths of both women.

The jury also found that an aggravated factor of substantial physical torture applied to Smith’s first-degree murder charge in the killing of Kathleen Jo Henry.

Smith, who is from South Africa, previously admitted to committing both murders in an interrogation on October 8, 2019, which was presented to the jury during the trial. Still, Smith pleaded not guilty to all charges.

Timothy Ayer, Smith’s defense attorney, said during closing arguments Thursday that the October interrogation was “fabricated” to trick Smith into confessing. Yesterday he called the interrogation “eight hours of pre-planned psychological warfare.”

ABC News contacted Ayer for further comment, but requests were not immediately returned.

During the trial, which began on February 6, Alaska state prosecutors presented graphic video and photographic evidence of Smith recounting his actions during Henry’s murder.

Police were brought to Smith when a woman claimed to have found an SD card labeled “Midtown Marriott Homicide” lying on the floor on Sept. 30, 2019, according to court documents.

The woman, Valerie Casler, later admitted to stealing the phone from Smith’s truck and transferring the contents to an SD card which she then turned over to police, she testified on the stand. She said that she lost the original phone.

Ayer argued that Casler is an unreliable source.

Prosecutors Brittany Dunlop and Heather Nobrega alleged that Smith killed Henry in a Marriott hotel room, as shown on cellphone videos, in Midtown Anchorage, Alaska. Prosecutors also argued that Smith killed Abouchuk in his living room with a green gun, which Smith confessed to during interrogation in October 2019.

“You will all bear the burden of knowledge,” Dunlop said at the start of the trial. “I am sorry that you bear the burden of this very, very heavy knowledge. But I am going to ask you to convict the defendant of all the charges against him.”

Prosecutors alleged Smith preyed on vulnerable women. Both victims, Henry and Abouchuk, were of Alaska Native descent. Both women, along with Casler, the woman who handed over the SD card, also felt homeless. Smith had picked Casler up from her temporary lodging when she stole his phone.

In an emotional testimony, Abouchuk’s daughter, Kristy Grimaldi, shared that her mother also experienced alcohol addiction.

“As a child, I didn’t really understand why or what my mother was like, but as an adult, I really felt for her,” Grimaldi said. “She even talked about, you know, going to treatment and it not being a good experience for her.”

Investigators found additional devices in Smith’s home containing deleted images and videos of Abouchuk’s alleged murder.

Smith faces a life sentence.
