I found him listed as "inmate in 1930 at Township 3, San Mateo, California". I would like to know what he was in prison for and for how long. He served in WW1 in the Spruce Production Divison, 40th Joice S.P.D. Co 124th. Can any one help me with this. Thank you, Kit Niemann Researching the men in the SPD
