John Gilbert Farfan, 50, walked away from a care facility in Santa Rosa, California, on February 22, 2011, and was not seen or heard from after leaving. A prolonged search followed but produced no immediate answers about his whereabouts.

Partial human remains were found in a creek bed in Shiloh Ranch Regional Park in Sonoma County in December 2013. Those remains were identified as Farfan’s in May 2015. The cause and circumstances of his death have not been resolved publicly, and investigators continue to look into how he came to be in the park and what led to his death.

If anyone knew John, saw him in February 2011, or has information about his movements in Sonoma or Santa Rosa, please come forward.
