Police seized nearly 1,900 marijuana plants during a major sweep Wednesday morning in San Jose.
The pot plants seized have a street value of around $3 million to $5 million. Police arrested a couple who investigators claim ran the operation, including four other people allegedly involved. The couple arrested has been identified by police as Dean Trinh and Kim Le.
Police called the pot-growing operation "elaborate" and was spread across seven homes turned into greenhouses throughout the city.
"This is going to require a lot more follow up investigation as to who the owners were of the properties," San Jose Police Department spokesman Albert Morales said.
The homes, which were newly renovated and turned into greenhouses, featured sophisticated lighting and ventilation systems. Police said the homes were also powered by stolen electricity.
Police said the landlord for one of the properties reported suspicious activity, which led to the sweep.
The Dubanski Drive owner, Susan Ra, said her family lived in the area for 40 years then hired a rental agency two years ago to manage the property.
Ra was stunned Wednesday to hear about the drug operation.
"I'm pretty shocked," she said. "I did not know (about) it."
Neighbors also were in shock to hear of the drug operation.
