A firefighter checking out a call to a White Bear Lake house last month found no flames, but plenty else to arouse suspicion.
There was the heat escaping from the eaves of the house, and frost on the inside of the windows, White Bear Lake Police Chief Lynne Tellers Bankes said Monday.
The homeowner arrived and said he would make sure all was well, Bankes said. But the firefighter described the curious signs to a police investigator, she said, and on Monday, about two weeks later, authorities busted a marijuana-growing operation in the house's basement and seized pot believed to be worth at least a couple of million dollars.
Ramsey County Undersheriff George Altendorfer said the enterprise was one of the largest pot-growing operations in the county's history.
A 27-year-old homeowner was taken into custody.
His toddler son, who was with him Monday, was turned over to child-protection authorities, Bankes said.
Discovery of the marijuana greenhouse follows similar busts in recent years in such Twin Cities area communities as Blaine, Forest Lake, Bloomington and Apple Valley. As in many of those cases, the White Bear Lake grower took advantage of a spacious basement and the peacefulness of his new suburban neighborhood.
The only apparent inhabitants of the house in the 3400 block of Michael Avenue, north of the Maplewood Mall, were more than 1,000 plants growing under about 40 umbrella-shaped metal lamp shades. According to Ramsey County property-tax records, the suspect and another person bought the 6-year-old house last Nov. 9 for $367,000.
