When a Person Commits a Crime, Is There Probable Cause to Search the Person’s Phone for Evidence?

The question in the title of this post is one that I’ve been asked lots of times in different factual contexts. The basic question is, given that most people have cell phones, and that people tend to use their phones to document and to communicate about just about everything that they do, is it reasonable to believe that a person who has committed a crime has evidence of that crime on his or her phone?

Real-Time Cell Phone Tracking Update, Including a New Case

The Court of Appeals of North Carolina recently decided a case about police obtaining real-time location information from a suspect’s cellular service provider. The case does not address the principal controversy concerning such information. Nonetheless, it provides a good refresher on the issue and marks a good time for an update on the national controversy about this issue.

Probable Cause and the Party at Peaches’ House

The United States Supreme Court issued its opinion in District of Columbia v. Wesby on Monday, holding that police officers had probable cause to arrest 16 people for unlawful entry after finding them reveling in a vacant house without the permission of its owner. The court further held that even if one assumed the officers lacked probable cause, they were entitled to qualified immunity because there was no clearly established law that rendered their actions unreasonable. The D.C. Circuit and the trial court had ruled otherwise, leading to a compensatory damages award of nearly $700,000 for the plaintiffs.

While trial courts are regularly called upon to evaluate whether facts known to an officer provide probable cause of criminal activity, it is less common for the Supreme Court to engage in such factbound determinations. Thus, the analysis in Wesby, whose language doubtless will soon be cited in the North Carolina reporters, warrants a closer look.

Last week, the court of appeals reversed a defendant’s conviction for first-degree murder. That doesn’t happen every day, so let’s unpack the case. The central issue concerns two eyewitnesses’ in-court identifications of the defendant.

Supreme Court of North Carolina: Officer Did Not Improperly Extend a Traffic Stop by Frisking a Driver and Ordering the Driver into a Patrol Car

In 2015, the Supreme Court of the United States decided Rodriguez v. United States, 575 U.S. __, 135 S. Ct. 1609 (2015). Rodriguez held that it was improper for an officer to extend a traffic stop for several minutes in order to conduct a dog sniff of the stopped vehicle. More generally, the decision requires an officer to pursue the “mission” of a traffic stop diligently, without measurably extending the duration of the stop for investigative activity unrelated to the purpose of the stop.

Our court of appeals has issued several decisions under Rodriguez, including some in defendants’ favor. Everyone has been waiting for those cases to make their way to the state supreme court. Now one has, and it turns out that the supreme court’s understanding of Rodriguez differs considerably from the view adopted by at least some panels of the court of appeals.

The case in question is State v. Bullock, __ N.C. __, __ S.E.2d __, 2017 WL 5017435 (2017), and this post explores it further.

New Book on Traffic Stops and Offenses

I’m pleased to announce that the School of Government has just released a new book entitled Pulled Over: The Law of Traffic Stops and Offenses in North Carolina. Shea Denning, Christopher Tyner, and I are the authors. It’s an important topic given that North Carolina officers conduct more than a million traffic stops each year and that many criminal cases, small and large, begin with a motor vehicle stop. This post provides more information about the book.

Should an Officer Use His or Her Personal Cell Phone to Take Work-Related Photographs?

I’ve been asked several times lately whether it is a good idea for an officer to use his or her personal cell phone to take work-related photographs, such as photographs of a crime scene or photographs of seized items. In this post, I explain why I think that’s OK, so long as it is consistent with agency policy.

Serial, Cell Site Location Information, and Experts . . . on a Wednesday

It’s not Thursday, but I’m going to throw it back a few years to 2014. Like the rest of the nerds I know, I became obsessed that year with the podcast Serial. The first season of that podcast chronicled the prosecution of Adnan Syed for the 1999 murder of his ex-girlfriend, Hae Min Lee. Host Sarah Koenig meticulously sifted through the evidence and conducted goodness-knows-how-many interviews with everyone connected to the case, including numerous recorded interviews with Syed, who is serving a life sentence in a Maryland prison. Syed claims that he did not kill Lee, whose body was discovered six weeks after she disappeared buried in a Baltimore park. Koenig spends the first several episodes of the podcast describing inconsistencies in witness’s accounts of the day Lee disappeared—inconsistencies that raise doubts about Syed’s guilt. But in episode five, Koenig, with the help of her producer, analyzes the evidence that the State offered regarding which cell towers serviced calls to Syed’s phone during the time that one of Syed’s friends claimed Syed was burying Lee’s body. The producer concludes:

“I think they were probably in [the park] . . .   Because . . . the amount of luck that you would have to have to make up a story like that and then have the cell phone records corroborate those key points, I just don’t think that that’s possible.”
