Police Blotter is a weekly CNET News.com report on the intersection of technology and the law.
What: Woman, sentenced to 25 years in prison for murdering her husband, appeals on Fourth Amendment grounds. Conviction based in part on GPS tracking and her Internet searches.
When: Texas appeals court rules on March 13.
Outcome: Sentence upheld.
What happened, according to court documents: For the last three years or so, Police Blotter has followed topics like police tracking vehicle movements through GPS and search engine history being used as evidence in court.
Texas resident Wendi Mae Davidson enjoys the dubious distinction of being a convicted murderer whose case involves both types of electronic monitoring.
Davidson's legal travails began on January 16, 2005, when she told the U.S. Air Force that her husband Michael Severance, an airman, had been missing since the day before. Air Force investigators and the San Angelo Police Department began parallel investigations, which led them to conclude it was unlikely that Severance had deserted.
Air Force Special Agent Greg McCormick did learn early on that Davidson owned a horse on a ranch, but investigators didn't know where it was. In hopes that Davidson would lead them to it, Air Force agents placed a tracking device on the underside of her car in the middle of the night on February 26.
One day later, "data retrieved from the device" showed that Davidson had driven to a ranch owned by Terrell Sheen, who told agents that he boarded horses including Davidson's and that they were welcome to search the property. The Air Force agents did: it proved to be an expansive ranch that included a barn, mobile homes, fenced corrals, and ponds.
Their search did not find Severance, the missing airman. On March 5, a Texas Ranger and a San Angelo sergeant interviewed Davidson at the veterinary clinic where she worked. They already knew at this point (it's unclear how they knew this) that the computer had been used to perform Internet searches on topics including polygraphs and the phrase "decomposition of a body in water." The police said Davidson became defensive when asked about the pond on Sheen's ranch and her Internet searches.
What you might expect to happen did, in fact, take place. Michael Severance's body was found in one of the ponds, with Davidson claiming she moved the body to protect a family member who might have been the murderer.
The police didn't believe her; she was charged with murder and two counts of tampering with evidence and, after a no-contest plea, was eventually sentenced to 25 years in prison. One report said Davidson owned a small animal clinic and had apparently poisoned her husband with a mix of phenobarbital and pentobarbital before weighing down his body with a boat anchor.
On appeal, Davidson's lawyers filed a motion to suppress evidence obtained from the tracking device. (It's not clear that it was a GPS-based unit, but because that's by far the most common, it's a fair assumption.) Her appeal said the tracking data should be suppressed because a judge's approval was necessary--and more specifically that it violated the Fourth Amendment, the Texas Constitution, and the Texas Code of Criminal Procedure.
Note that while her husband was a member of the U.S. military, Davidson was not, and the same Fourth Amendment standards that circumscribe the actions of local police should presumably circumscribe the actions of federal investigators as well.
If the same rules apply, what should those rules be? Courts have split on the topic; here's a review of cases I wrote in 2005. Suffice it to say that a pair of U.S. Supreme Court cases--U.S. v. Knotts and U.S. v. Karo--established that police don't need court approval to track suspects, at least when using a crude radio beeper.
This is basic law school criminal procedure. There is no legitimate expectation of privacy outside one's home, with few exceptions. Post 9/11, we're lucky there's still an expectation of privacy at all in the US.
To expect someone on MY property from the Government, or otherwise, isn't trespassing? People would need to build moats and the great wall of china around their land to facilitate this ridiculous request. If it's my land, visible from the road or not, DOES NOT mean you are entitled to be on it. What the hell?
No expectation of privacy in any public area, okay. No expectation of privacy in any area viewable from a public area, okay with limitations (no binoculars, etc). But, the police now have free access to any part of private lands they wish to enter? Is anything they see from such private property in an area that is not normally viewable from public areas now good evidence? They can now wander at will through private lands? Private lands are now "public areas" so far as the police are concerned?
I have some problems, here. Such encroachment always expands.
Throw out her sentence for the warrantless tracking device: Sentence her to life for her double stupidity in disposing of the bod in a place with such a close nexus to the husband's hobby and for doing that search on a computer with such a close nexus to her day-to-day life. Oops, forgot, we cant incarcerate people for stupidity -- well, then sterilize her.

The "open field" part of the decision referred to the legality of the tracking device, not a search.
