Deaths in that town were about 10x normal for the month of March. I estimate the IFR by looking at the serological results showing 70% were infected, and observe that 1.4% of the population of the town died in March. 1.4%/70%=2% of those infected died. Now it could be that there was some other cause for the death rate in the town to be 10x normal, but I think that's pretty unlikely. That said, I'm sure there are excess deaths from other causes, like heart attacks that didn't go to the hospital because they were overloaded, etc, but you could consider those deaths to be indirectly from COVID as well.
