Is a "mere visitor" subject to a search warrant?

In People v. Berry (1990) 224 Cal.App.3d 162, 273 Cal.Rptr. 509, this court considered the characteristics which distinguish a visitor from an occupant for Fourth Amendment purposes. The issue before the court was whose personal property law enforcement officers could search pursuant to a warrant to search a residence. We held, if the circumstances apparent to the searching officers show indicia of only a casual, temporary presence at the place being searched, the person is a "mere visitor" whose property cannot be searched solely because it happens to be located on premises named in the warrant. If the circumstances suggest a relationship between the person and place sufficient to connect the individual to the illegal activities giving rise to the warrant, search of the person's property on the premises is permitted.
