Officials worried about a surge in suicides in southwestern Illinois’ Saint Clair County said they hope increased use of social media about the issue saves lives.  The 22 suicides declared by the county’s coroner this year through July are just five fewer than the number over all of 2013, the Belleville News-Democrat reported.  The number of people who have taken their own lives in the county has ranged from 19 to 37 since 2008.  The reasons for the growing number of suicides this year remain elusive.  The county’s board chairman, Mark Kern, signed a proclamation Monday to raise awareness about this growing danger.  Kern also met with members of the Suicide Prevention Alliance and the county’s mental health board in recognition of National Suicide Prevention Week.  About 20 county organizations will turn to social media such as Facebook and Twitter to post links and videos about suicide prevention, the newspaper reported.
