Alexander Renner, 37, was staying with 52-year-old David Knotts at a Vienna Drive NE home in Albuquerque in spring 2022. Renner was last seen walking into the house in May. On May 4 the two men had an altercation that ended when Knotts fatally shot Renner in the head. Knotts then wrapped Renner’s body in a rug and left it hidden in the garage.

Renner’s family reported him missing in June 2022 after they were unable to contact him. Neighbors later noticed a foul odor coming from the Vienna Drive home. By September detectives identified Knotts as the primary suspect, obtained a search warrant, and on September 22, 2022 found Renner’s decomposed remains still rolled up in the rug inside the garage. Police determined Knotts was responsible for Renner’s death and arrested him in December 2022 on murder and evidence-tampering charges.

If anyone knew Alexander, his movements that spring, or saw anything unusual at the Vienna Drive residence, please come forward with information.
