Keith Green, 27, of Millbrae, California, was reported missing on April 29, 2016, after he failed to return home following a meeting with his ex-girlfriend, Tiffany Li, at the Millbrae Pancake House. He left behind his wallet, car, and other personal belongings; his phone was later found by a hiker in Golden Gate Park. A decomposing body discovered May 11, 2016, near a homeless encampment between Healdsburg and Geyserville was identified as Green, and an autopsy ruled his death a homicide.

The investigation produced multiple arrests: Tiffany Li, her boyfriend Kaveh Bayat, and their former bodyguard Olivier Adella. Authorities alleged Li and Bayat orchestrated the killing because Li feared losing custody of her children to Green, and that Adella had been hired to dispose of the body. Search warrants were executed at residences in Burlingame and Hillsborough.

The criminal cases drew extensive publicity. Li and Bayat were charged with murder; Adella was initially linked as an alleged accessory and had agreed to cooperate under a deal that was later revoked when he did not honor it. During the trial both Li and Bayat accused Adella of being the killer. A civil wrongful death suit by Green’s mother was set to go to trial in January 2022.

Did anyone who knew Keith or saw him in late April 2016 notice anything unusual about his plans or contacts?
