Content: They point to data showing that suicides, often thought to occur mostly in the dreary, socially isolating winter months, actually spike in the spring, starting in April. There is debate about why, although the prevailing explanation is that the increase in sunlight improves mood and energy just enough for suicidal people to make plans and follow through. “They can muster the energy to do something,” said Lankford, the Alabama professor. The timing of the suicidal spike is important, experts say, because many mass shootings and other violent attacks are thought to be a form of suicide among the socially isolated. Harris and Klebold killed themselves. Cho, the Virginia Tech shooter, killed himself. In April 2009, Jiverly Antares Wong killed himself after fatally shooting 13 people at an immigration center in Upstate New York. “You have these people coming out of hibernation from the winter with all their anger peaked and ready to go,” Lankford said, adding that their rage may build as they see people out having fun together in groups. “ That highlights the discrepancies between those who are socially healthy and those who aren’t.” Experts on school shootings think that spring’s relationship to suicidology could offer another explanation — besides Columbine — for why so many of those incidents happen after the winter.
