Researchers have developed a new technique that can potentially link serial killer victims based on subtle facial similarities. The concept was based on the victims' notorious killer, Ted Bundy, selected for his crimes. The researchers found a number of the victims had similar facial geometrics than those randomly selected from a public database. The application of the research could be a new tool to help law enforcement working on unsolved cases, linking victims to known killers.
Children as young as 6 months can show empathy for victims. The findings debunk the theory that the ability to empathize only develops after one year of age.
