Reviewing only those cases closed by investigators and then only those closed as an unknown, the worldwide number narrows to 99. And 84 of those cases were U.S.
Now looking at just the U.S. 84 cases – they were filed from 32 states ranging from 1 to 8 cases per state. The totals were typical where more cases were reported from the higher-populated states. So Texas has 8 of those cases; Missouri, California and Ohio each have 7 cases; and Pennsylvania had 6 cases.
But one state stood out from the list – Iowa with 5 cases.
