Bugs
If already established as a Minuteman settlement, the quest target may show as Jamaica Plain (possibly other locations as well) settlers. Killing the targeted settlers doesn't seem to affect anything and the quest is completed as normal. However doing so will also potentially affect the standing of whatever companion you're with.
