The Pennsylvania Superior Court has decided the case of Commonwealth v. Rosendary, holding that the police do not need a search warrant to get a parolee’s GPS monitoring data from parole agents so long as the parolee was already on GPS monitoring for reasons unrelated to the investigation of the new crime. In this case, the defendant’s GPS monitor put him at the scene of the crime, but the police had obtained that data without getting a search warrant for it. The Superior Court, however, rejected Rosendary’s arguments that the evidence should be suppressed, finding that police do not need a search warrant to get this type of data from parole agents and that the police did not use the parole agents as “stalking horses” for the police investigation.  

The Facts of Rosendary

The defendant was on parole for a robbery conviction. As part of his parole, he was eventually placed on GPS monitoring. He signed a consent form agreeing to the monitoring. He did not have much of a choice, though, as the alternative to GPS monitoring would have been incarceration. The police subsequently arrested him and charged him with another robbery. At his trial, the Commonwealth introduced evidence from his parole GPS ankle monitor which incriminated him by putting him at the crime scene.

Prior to trial, the defendant moved to suppress the GPS data. He argued that the police should have obtained a search warrant in order to get the GPS information from his parole agent and that alternatively, the parole agent had worked as a “stalking horse” for the police in order to evade the warrant requirement. The trial court denied the motion to suppress, and the defendant appealed.

The Superior Court’s Ruling

The Pennsylvania Superior Court denied the appeal. First, it rejected the defendant’s argument that the police violated the Fourth Amendment’s warrant requirement by getting the GPS data without a search warrant. Although the police ordinarily need a search warrant in order to get GPS location data for a suspect, the Court held that they did not need to get a search warrant in this case. Specifically, the defendant had a diminished expectation of privacy in his GPS data because he was on parole, he had agreed to wear the monitor in lieu of incarceration, and he knew that the data would be shared with his parole agent. Thus, he had no reasonable expectation that the data would be kept private, and he had agreed to wear the ankle monitor. Therefore, law enforcement did not need a search warrant to get the data. Further, the parole agent had not shared unlimited data with the police. Instead, the parole agent had shared only the location data for where the defendant was at the time of his suspected involvement in the robbery. The Court found that this was not a significant intrusion into his privacy because the data shared was limited in time and scope.

The Court also rejected the defendant’s stalking horse challenge. Under the stalking horse doctrine, the police may not take advantage of a suspect’s status as a probationer or parolee to avoid the warrant requirement. In other words, the police may not ask probation or parole to conduct a warrantless search for the purpose of finding evidence related to a police investigation. Instead, the police should get a warrant. For example, if a defendant could show that the police had asked a probation officer to conduct a search of the defendant’s house to look for evidence because the police suspected the defendant of a crime, then that search could potentially violate the stalking horse doctrine and require suppression of the evidence. Here, however, the defendant introduced no evidence that the police had directed the search or directed parole to put the defendant on GPS monitoring. He was already on GPS monitoring, and the police simply requested the data from his parole agent. As he did not have a reasonable expectation of privacy in the data, the parole agent was free to share this information with the police.

The Takeaway

This result is not particularly surprising. It is usually not possible to suppress evidence that was shared with the public as suppression requires a reasonable expectation of privacy. A probationer or parolee who is subject to GPS monitoring has no real reason to believe that the evidence would be kept private, so courts are generally not going to suppress it.

As a general rule, it’s best not to commit new crimes while wearing a probation or parole GPS tracking device. The evidence will likely be admissible in court, and the police will not be required to get a search warrant for the evidence. There is still the possibility of challenging the collection of this type of evidence should the defendant be able to show that probation or parole improperly conducted a search at the request of the police and that the police may not have otherwise had the authority to conduct such a search, but that type of violation is often difficult to prove.
