Overview

• Tyler McCain was booked into the Shasta County Jail without bail on Wednesday and is scheduled for arraignment Friday.
• Nikki, 39, vanished in May 2024; her Chevy Avalanche was found near the Shasta–Tehama county line with a strong odor of decomposition and a blood‑stained sheet later confirmed as hers.
• Prosecutors cite additional forensic findings tying Tyler’s DNA to items from the vehicle and say a confidential informant reported he admitted killing her after a domestic‑violence incident.
• In April 2025, deputies found Nikki’s partially burned driver’s license in Tyler’s wallet during a traffic stop, according to investigators.
• The district attorney will seek murder with a special‑circumstance allegation, refile 2023 domestic‑violence counts and add firearm, ammunition, forgery and traffic charges, while searches continue and a $30,000 reward seeks tips to locate Nikki.
