A search for two young siblings missing in a heavily wooded area near their Nova Scotia home prompted the Canadian Broadcast Corporation to tap Robert Koester, author and app creator of Lost Person Behavior, for insight on what search-and-rescue teams face. Koester, who is also a search mission coordinator with the Virginia Department of Emergency Management, said the first thing searchers need to consider are the basics of a solid investigation, such as the child’s age, scenario, timeline, and what caused them to go missing. Searchers can apply that information to statistics to identify high probability areas. For example, half of lost 4- to 6-year-olds—the ages of the missing siblings—are typically found less than one-half mile away, Koester said. Among his insights: Be aware that a child may not shout back when a searcher is shouting their name and may actively hide because they may be afraid or think they’re in trouble. Thick underbrush “may look impenetrable to you as the adult searcher standing up at five feet. But if you’re down at between one and three feet, you may see a way to scramble underneath … So all those places need to be searched,” Koester said.






















In his “Genetic Genealogy” presentation, crime scene forensics expert Ed O’Carroll cited several ways to “give people back their names,” adding “crime is more solvable than ever before.”
• Be a “genetic witness”: Encourage people on the genealogy sites GEDmatch and AncestryDNA to opt in to giving law enforcement a broader field of DNA samples to consider when trying to pinpoint someone who may have committed a violent crime. “As many of us know, CODIS only gives a hit about half the time we use it.”
