Anton Mutu, 30, was reported missing from Carmichael by his wife Tuesday morning, Sonoma County sheriff's Sgt. Jim Naugle said this afternoon.
Mutu's BMW SUV was found Wednesday in the parking lot of the 805-acre Armstrong Redwoods State Natural Reserve adjoining the 5,683-acre Austin Creek State Recreation Area.
The third day of the search began at 7:30 a.m. today and will continue until darkness, Naugle said.
It's unknown if Mutu has a cellphone with him and has tried to use it because coverage in that area of west Sonoma County is poor, Naugle said.
There is no evidence foul play is involved in Mutu's disappearance, Naugle said.
