A Minnesota father was convicted this week of murdering his teenage son in a case that hinged on a combination of digital forensics and industrial-scale landfill search technology. Steven Pladson, 44, was found guilty of second-degree murder in the death of 14-year-old Landen Pladson, whose remains were recovered from a landfill in Sherburne County in 2022. The verdict, delivered on October 7, 2026, in Benton County District Court, marks the culmination of an investigation that relied heavily on cell phone location data, vehicle GPS records, and a methodical grid search of thousands of tons of waste.
**Context**
Landen Pladson was reported missing on August 12, 2021, after he failed to return home from a friend’s house in Foley, Minnesota. His father, Steven Pladson, initially claimed he had dropped the boy off near a local park. However, inconsistencies in his account quickly drew the attention of law enforcement. Investigators from the Benton County Sheriff’s Office and the Minnesota Bureau of Criminal Apprehension obtained warrants for cell phone tower records, which showed that Steven Pladson’s phone had traveled to a remote area near the town of Rice on the night of Landen’s disappearance — a location inconsistent with his stated route.
Further analysis of the father’s vehicle GPS system revealed that his pickup truck had stopped for an extended period at a rural gravel pit. When authorities searched the site, they found traces of blood and a spent shell casing. The digital evidence placed Steven Pladson at the scene during the critical window of time. Despite this, Landen’s body was not immediately found. Investigators believed the remains had been disposed of in a commercial dumpster that was later transported to the Elk River Landfill, a massive facility that processes waste from multiple counties.
Finding a body in a landfill is a notoriously difficult task. The Elk River Landfill receives hundreds of tons of waste daily, and by the time the search began, the relevant material had been buried under layers of fresh garbage. The search team, which included FBI evidence response specialists, used a combination of ground-penetrating radar, aerial drone imagery, and a systematic grid search protocol. They also employed a custom software algorithm developed by the University of Minnesota’s Department of Civil, Environmental, and Geo- Engineering to predict the likely location of the remains based on landfill compaction records and truck delivery logs. After weeks of digging, Landen’s skeletal remains were recovered in October 2021.
**Analysis**
The Pladson case illustrates how modern law enforcement increasingly relies on technology to solve crimes that would have been nearly impossible to crack a generation ago. Cell phone location data, once considered novel, is now routine in homicide investigations. In this case, it provided the critical link between the father’s account and the physical evidence. The GPS data from the vehicle was equally damning, showing a deviation that the defendant could not explain. These digital breadcrumbs are now admissible in court under the U.S. Supreme Court’s Carpenter v. United States framework, which requires a warrant for historical cell site data but allows its use once obtained.
Perhaps the most technologically striking aspect of the case was the landfill search. The use of predictive modeling to narrow down a search area within a landfill is a relatively new forensic technique. The algorithm, developed with grant funding from the National Institute of Justice, analyzes waste compaction patterns, truck arrival times, and the specific cell where the dumpster was emptied. This approach dramatically reduced the search area from several acres to a few hundred square feet. Without it, the recovery might have taken months or never occurred at all. The success of this method is likely to encourage other jurisdictions to adopt similar tools for cases involving landfill disposal.
