The way i read it is that "Hot Sun
Spa" was busted after receiving complaints, then got a search warrant and found items relating to prostitution. But it did not mention other parlors being busted after receiving complaints. They could of been set up after a undecover
LE went in and was offered a service, then proceeded with a search warrant. "There are more ways than 1 to catch a fish" I believe since this was the last known parlor to front prostitution, all the mongers ventured off there setting off a chain reaction of complaints.
. There might be more spas, but one can dam well expect that the other parlors(in that county) will be "Gun Shy" due to what is going on. Referring to the article by "jj1492"
