An investigation uncovered disturbing new details in the murder-for-hire case of a Minnesota teenager. For more than two years, Peter Van Sant has been on a journey through the dark web, investigating websites that advertise hitmen for hire. His 2018 report “Click for a Killer” exposed about 20 active murder plots. Van Sant joins “CBS This Morning” to discuss the investigation, airing on "48 Hours" Saturday at 10/9c on CBS.
