Under the “open fields” doctrine, evidence that a body was found 450 feet from the defendant’s house during random digging done at the direction of the sheriff acting without a warrant was properly admitted into evidence. Conrad v. State, 63 Wis. 2d 616, 218 N.W.2d 252 (1974). Seizure by police of a large quantity of marijuana from the defendants’ 155-acre farm did not contravene their 4th amendment rights. State v. Gedko, 63 Wis. 2d 644, 218 N.W.2d 249 (1974). The search of the defendant’s wallet after the defendant’s arrest on unrelated charges that led to the discovery of a newspaper article about a crime that, after questioning, the defendant admitted to committing was proper in order to find weapons or contraband that might have been hidden there. State v. Mordeszewski, 68 Wis. 2d 649, 229 N.W.2d 642 (1975). The seizure by police officers of a box of cartridges from under the edge of a couch on which the defendant was resting at the time of the defendant’s arrest was proper under the plain-view doctrine, since if police had a prior justification to be present in a position to see an object in plain view and its discovery was inadvertent, the object may be seized, and the use of a flashlight by one of the officers did not defeat the inadvertence requirement. Sanders v. State, 69 Wis. 2d 242, 230 N.W.2d 845 (1975). A warrantless search of two persons for concealed weapons was reasonable when an armed robbery with a sawed-off shotgun had been committed a short time before by two men, one of whom matched the description given for one of the robbers. Penister v. State, 74 Wis. 2d 94, 246 N.W.2d 115 (1976). The doctrine of exigency is founded upon actions of the police that are considered reasonable. The element of reasonableness is supplied by a compelling need to assist the victim or apprehend those responsible, not the need to secure evidence. West v. State, 74 Wis. 2d 390, 246 N.W.2d 675 (1976). A warrantless search by a probation officer was constitutionally permissible when probable cause existed for the officer to attempt to determine whether the probationer had violated the terms of probation. State v. Tarrell, 74 Wis. 2d 647, 247 N.W.2d 696 (1976). The plain view doctrine does not apply if the observation is not made inadvertently or if the officer does not have the right to be in the place from which the observation is made. State v. Monahan, 76 Wis. 2d 387, 251 N.W.2d 421 (1977). Discussing the criteria used as justification for warrantless searches of students by teachers. L.L. v. Circuit Court, 90 Wis. 2d 585, 280 N.W.2d 343 (Ct. App. 1979). A warrantless entry under the emergency rule justified a subsequent entry that did not expand the scope or nature of the original entry. La Fournier v. State, 91 Wis. 2d 61, 280 N.W.2d 746 (1979). An investigatory stop-and-frisk for the sole purpose of discovering a suspect’s identity was lawful under the facts of the case. State v. Flynn, 92 Wis. 2d 427, 285 N.W.2d 710 (1979). Furnishing police with the bank records of a depositor who had victimized the bank was not an unlawful search and seizure. State v. Gilbertson, 95 Wis. 2d 102, 288 N.W.2d 877 (Ct. App. 1980). Evidence obtained during a mistaken arrest is admissible as long as the arresting officer acts in good faith and has reasonable articulable grounds to believe that the suspect is the intended arrestee. State v. Lee, 97 Wis. 2d 679, 294 N.W.2d 547 (Ct. App. 1980). A warrantless entry into the defendant’s home was validated by the emergency doctrine when the officer reasonably believed lives were threatened. State v. Kramer, 99 Wis. 2d 306, 298 N.W.2d 568 (1980). The warrantless search of a fisherman’s truck by state conservation wardens under statutory inspection authority was presumptively reasonable. State v. Erickson, 101 Wis. 2d 224, 303 N.W.2d 850 (Ct. App. 1981). Under Tyler, 436 U.S. 499 (1978), the warrantless search of an entire building on the morning after a localized fire was reasonable as it was the continuation of the prior night’s investigation that had been interrupted by heat and nighttime circumstances. State v. Monosso, 103 Wis. 2d 368, 308 N.W.2d 891 (Ct. App. 1981). A warrantless entry into a home was validated by the emergency doctrine when an official’s reasonable actions were motivated solely by the perceived need to render immediate aid or assistance, not by the need or desire to obtain evidence. State v. Boggess, 115 Wis. 2d 443, 340 N.W.2d 516 (1983). Police having probable cause to believe a vehicle contains criminal evidence may search the vehicle without a warrant or exigent circumstances. State v. Tompkins, 144 Wis. 2d 116, 423 N.W.2d 823 (1988). Fire fighting presents exigent circumstances justifying a warrantless entry. A fire fighter may contact police to inform them of the presence of illegal possessions in plain view. A subsequent warrantless search and seizure is proper. State v. Gonzalez, 147 Wis. 2d 165, 432 N.W.2d 651 (Ct. App. 1988). A reasonable police inventory search is an exception to the warrant requirement. At issue is whether an inventory is a pretext for an investigative search. State v. Axelson, 149 Wis. 2d 339, 441 N.W.2d 259 (Ct. App. 1989). When effecting a lawful custodial arrest of an individual in the individual’s home, a law enforcement officer may conduct a search of closed areas within the immediate area of the arrestee even though the search imposes an infringement on the arrestee’s privacy interests. State v. Murdock, 155 Wis. 2d 217, 455 N.W.2d 618 (1990). Under the circumstances presented, an officer properly conducted an inventory search resulting in the discovery of contraband in a purse left in a police car because the search was conducted pursuant to proper department policy. State v. Weide, 155 Wis. 2d 537, 455 N.W.2d 899 (1990). Police corroboration of innocent details of an anonymous tip may give rise to reasonable suspicion to make a stop under the totality of the circumstances. A suspect’s actions need not be inherently suspicious in and of themselves. State v. Richardson, 156 Wis. 2d 128, 456 N.W.2d 830 (1990). The validity of a “Good Samaritan” stop or entry requires that the officer has the motive only to assist and not to search for evidence, has a reasonable belief that the defendant needs help, and once the entry is made absent probable cause, that objective evidence exists giving rise to the investigation of criminal behavior. State v. Dunn, 158 Wis. 2d 138, 462 N.W.2d 538 (Ct. App. 1990). The reasonableness of a search does not come into question unless a person has a reasonable privacy expectation. There is no reasonable expectation of privacy in TDD communications made from the dispatch area of a sheriff’s department. State v. Rewolinski, 159 Wis. 2d 1, 464 N.W.2d 401 (1990). A parolee’s liberty is conditional. A judicially issued warrant is not required for the seizure of an alleged parole violator in the parolee’s home. State v. Pittman, 159 Wis. 2d 764, 465 N.W.2d 245 (Ct. App. 1990). The evidentiary search of a person not named in a search warrant, but present during the search of a residence reasonably suspected of being a drug house, was reasonable. State v. Jeter, 160 Wis. 2d 333, 466 N.W.2d 211 (Ct. App. 1991).
