After the Columbine massacre, members of a local church planted 15 linden trees as a memorial to the 15 people who had been killed — the 13 victims and two shooters. A couple of weeks later, while onlookers cheered, some parents of the dead children marked 13 trees with the names of the victims and chopped down the remaining two that represented the killers.
