There's a family story that Charles Milton landed in a Mexican jail because someone committed suicide in his bar (probably in Agua Prieta, Sonora). His daughter managed to eventually get him out (working from Arizona) and he moved to live with her in Douglas, Cochise, AZ.
He appears to have moved in with his daughter about 1939 and he died in 1942. So, the jail/prison time was before 1939. Where might I find records relating to something like this? I've looked pretty thoroughly through the online US newspapers.
