On 9 August 2010 the Statewide Narcotics Task Force, flying marijuana-eradication missions over eastern Connecticut with National Guard helicopter support, spotted cannabis plants on a Canterbury property from the air.[1] Ground officers went to 41 Raymond Schoolhouse Road, where they found four people at a property whose home and large two-story barn had been converted into a multi-stage cultivation operation around a greenhouse.[2][1]

Officers seized 1,102 marijuana plants in various growth stages, which police valued at about $1 million, along with $1,600 in cash and cultivation equipment.[2] Richard Houghtaling, Thomas Phravixay, Sisouk Phravixay and William Eichin faced charges including cultivation of marijuana over one kilo and operating a drug factory, and were held on a combined $150,000 bond for court in Danielson the next day.[2] The task force called it one of the largest residential cultivation operations ever found in Connecticut.[1]
