Police receives an anonymous complaint of underage drinking at a house officer did not knock on the front door. Instead, while Officer Wood remained on the front lawn, OfficerJohnsonwalkedontothe side yard of the single-story house. The side yard was an open area covered in grass. No fence, gate, or shrubbery suggested entrance was forbidden. There was not a walkway or an entrance to the home accessible from the side yard. A cement block wall marked the property line between the defendant's side yard and the home of his immediate neighbor. Defendant's home was set back about 20 feet from the public sidewalk. About10feet from the front of the house, OfficerJohnsoncame upon a large side window. The window is visible from the public street or sidewalk, but the inside of the room is not. The neighbor on that side of the house would have difficulty seeing into the window because of the high cement block wall separating the two homes.OfficerJohnson, standing on the darkened side of the yard outside the window, heard music coming from the stereo inside the room, although the music was not loud. A light bulb dimly lit the room. Looking in the window, OfficerJohnsonsawDefendant seated at a table with several baggies with a white powdery substance. The officers then based on probable cause, received a search warrant. Upon returning the next day and searching the house, the officers found several bags of drugs and arrested the Defendant.
