County Mayor Tim Stribling and Smithville Mayor Jimmy Poss signed proclamations Thursday declaring September Suicide Prevention Month in both DeKalb County and the City of Smithville. DeKalb County's age-adjusted suicide rate was 15.7 per 100,000 people, translating into three reported suicide deaths in 2013, the most recent year county-specific figures are available for. Two of the victims were female and one was male.
