Narcotics investigators made a bizarre find in a Rock Hill subdivsion this week. 

They said a man was growing more than $200,000 worth of marijuana inside his house in the Carnegie Estates neighborhood.

"It's just amazing that things like this can happen in your own neighborhood," said neighbor Amanda Weakland.

This week, narcotics officers obtained a warrant to search the house on Favorwood Drive. Deputies said 27-year-old Calvin Hoang rented the house. 

Inside, they found 128 marijuana plants growing on the second floor.  The operation was so sophisticated, it even had a filtering system to cut down on the drugs' smell, investigators said.

"He just used to come and go rarely. You wouldn't see him that often," said Jackie Meadows about her neighbor Hoang. 

Narcotics officers said nice neighborhoods are now attracting grow houses.

"You pay a little more for the rent, but in the end it's a whole lot less risk that you're going to get caught," said Cmdr. Marvin Brown of the York County Multijurisdictional Drug Enforcement Unit.

He said recent helicopter flights searching for marijuana outside have driven the illegal crops indoors.

"You could probably go for years without getting caught," said Brown.

Brown said narcotics agents in Charlotte told investigators there could be suspicious activity at the house, and that's why they started investigating.

Hoang is currently in jail facing charges of trafficking and manufacturing marijuana.
