I first thought "in quam" was a Latin expression, perhaps from the Napoleonic Code and used only in Louisiana,  related to sales by decedents or estates.  Then it occurred to me, perhaps after watching the John Oliver video last night, that the land was "in Guam."  (Oliver pointed out that "GUAM" looks like a graphic from the old Batman series where "BAM" and "POW" would flash on the screen at appropriate moments.)
