Los Angeles County prosecutors say a man who built a Mojave Desert compound known as Phonehenge West has been sentenced to almost 18 months in jail because he failed to pay for its demolition.

The L.A. Times reports Friday that Alan Kimble Fahey was ordered to pay more than $83,000 in costs incurred for the dismantling of the 20,000-foot labyrinth of interconnected structures and telephone poles. But Fahey has repaid just $1,250 to the county.
