City of Casey issued the following announcement on March 3.
Some of you may receive or have received a mailer from the Illinois Sheriffs' Association referencing the Clark County Sheriff's Office and having Sheriff Brown's name attached. This is a legitimate request asking for our local residents to become Associate Members. The ISA never solicits by phone. The ISA offers scholarships to local students in Clark County which are partially funded by our local Associate Membership dues. If you receive a mailer please consider it. Also, this is one of the only fundraisers we participate in and never by phone
