Dale Williams, Sr., was indefinitely committed in May 2005 under the Minnesota Sex Offender Program, a program administered by the Minnesota Department of Human Services. He is currently a civil detainee in a MDHS facility in Carlton County, Minnesota. His son is a vulnerable adult who resides in a group home after the Polk County District Court appointed a guardian for the son in 2004. In this 42 U.S.C. § 1983 action, Williams alleges that Cal Ludeman, Commissioner of Human Services, and James Arneson, a Polk County Social Services supervisor, violated Williams's federal constitutional right to contact his son by denying visits, blocking phone calls, and preventing his son from writing. The district court1 dismissed these claims based upon defendants' showing that they were not personally involved in limiting contacts between Williams and his son. Williams appeals.
