Statistically, there is unlikely to be a repeat, at least in the Evansdale area.
I live in Iowa, about 90 miles from Evansdale. After 13 July, there were no children to be seen in my tiny little town without parents, which is highly unusual. This is a place where it's common to see little packs of children playing and riding bikes from spring to late fall. Even at Wal-Mart where it is common to see a parent pushing the cart and a couple of children sort of orbiting the parent at a distance, children were under tight control.
Last summer there were several reports of attempted abductions that turned out to be misunderstandings, no abduction intended.
What good could a warning do that wasn't already being done? And how much higher would the tension level have gone had there been more warnings.
Tangential thought: driving in other states, I was always amused at the "bridges may ice over before the road" and "curves may be slippery" signs on the roads. That seems like nannying drivers, who shouldn't get behind a wheel if they don't know that stuff. Plus, reading (or hearing) a warning over and over tends to desensitise people to the subject of the warning.
