The defendant, Patricia Smith, appeals the decision of the Superior Court (Vaughan, J.) denying her motions to suppress. We affirm.
The following facts are not in dispute or are supported by the record.
The defendant was charged with one felony count of manufacturing marijuana, a controlled drug. See RSA 318-B:2 (2011). She moved to suppress evidence obtained when the police searched her property on November 20, 2009. Following a hearing, the superior court denied her motion. The defendant then filed a supplemental motion to suppress, which the court also denied.
In September 2009, the Grafton County Sheriff's Department received a tip that the defendant was growing marijuana inside her house at the corner of Deerfield Drive and Lakeside Drive in Haverhill. In response, Detective Frederic James III began an investigation by obtaining the defendant's electric bills from the power company, which indicated unusually high usage year-round. He then learned from the New Hampshire Department of Employment Security that the defendant was likely working without paying taxes, self-employed, or not working at all. He also drove past the defendant's house and noticed two air vents, one of which he described in the affidavit accompanying the warrant application as a "typical dryer-style vent" and the other as a "powered exhaust vent." His suspicions thus aroused, Detective James enlisted Sergeant Gary Prince of the New Hampshire State Police to help him investigate the matter further.
On November 12, 2009, James and Prince went to the defendant's property after dark and entered a wooded area behind her home to conduct surveillance. Several minutes later, they observed a power vent turn on; soon after, they smelled an odor of fresh marijuana permeating the air. Ten minutes later, the vent turned off and the smell dissipated. About an hour later, the vent again turned on, and the officers again smelled fresh marijuana in the air. When they left the wooded area, they no longer smelled the odor of marijuana.
On November 15, James and Prince again entered the wooded area behind the defendant's home, and again noted a correlation between the activation of the power vent and an odor of fresh marijuana. They also noticed that the odor was not present when they walked away from the defendant's house, but became stronger when they approached the house. They made similar observations on a visit to the wooded area behind the defendant's house on November 17.
On the basis of their observations on the three nights during which they visited the woods behind the defendant's house, James and Prince obtained a warrant to search it. The defendant moved to suppress evidence obtained during the search, arguing that the officers should have obtained a search warrant before entering the wooded area and that the search warrant for the house lacked probable cause.
At the suppression hearing and in the affidavits supporting the warrant, both James and Prince explained that they had substantial training in detecting the odor of fresh marijuana. James testified that they entered an unmaintained wooded area behind the defendant's property and throughout their surveillance of her house stayed well behind a stone wall separating the woods from a mowed lawn. He estimated that the defendant's property was one-third of an acre in size. He also testified that they retrieved information about the property lines from the registry of deeds and tried to measure where the defendant's property ended to avoid entering it. He admitted, however, that they crossed onto her property during their investigation. The superior court denied the defendant's motion to suppress, concluding that the officers did not enter the defendant's curtilage and that the evidence presented to the judge established the requisite probable cause.
When reviewing a trial court's ruling on a motion to suppress, we accept the trial court's findings unless they lack support in the record or are clearly erroneous. State v. Beauchemin, 161 N.H. 654, 656 (2011). We review legal conclusions de novo. Id.
The defendant argues that the police violated Part I, Article 19 of the State Constitution because they entered the curtilage of her home without first obtaining a warrant. She argues that she had a reasonable expectation of privacy in the wooded area behind her home because of its close proximity to the house itself and because the police did not make their observations from a public vantage point. The State contends that the defendant had no such reasonable expectation of privacy because the area searched, though in close proximity to her home, was outside the home's curtilage.
Part I, Article 19 of our State Constitution protects all people, their papers, their possessions and their homes from unreasonable searches and seizures. State v. Goss, 150 N.H. 46, 48 (2003). To receive constitutional protection in the area searched in this case, the defendant must have exhibited a subjective expectation of privacy in the area and that expectation must be one that society is prepared to recognize as reasonable. Goss, 150 N.H. at 48-49.
We have long adhered to the common law principle that certain property surrounding a home deserves the same protection against unreasonable searches and seizures as the home itself. State v. Pinkham, 141 N.H. 188, 190 (1996); State v. Pinder, 128 N.H. 66, 74 (1986). Such areas, known as curtilage, were traditionally accorded constitutional protection and required either a warrant or circumstances falling within a recognized exception to the warrant requirement before they could be entered or searched. State v. Johnson, 159 N.H. 109, 111 (2009). The boundaries and contents of the curtilage are not easily described. Pinkham, 141 N.H. at 190. We have stated that the curtilage includes those outbuildings that are directly and intimately connected with the habitation and in proximity thereto and the land or grounds surrounding the dwelling which are necessary and convenient and habitually used for family purposes and carrying on domestic employment. Johnson, 159 N.H. at 112; Pinkham, 141 N.H. ...
