This message from WHS:

Dear Wellesley High School Community,

I am writing to you today with profound sadness to inform you that one of our students, Vic Klenk, has died. Our thoughts and sympathies are with Vic’s family and friends. The family has requested that information about the cause of death not be shared and we believe it is important to respect their wishes and privacy during this difficult time. — Principal Jamie Chisum

This from Swellesley:

Vic, an avid horseback rider and nature lover, was looking forward to attending college next fall. We are told they loved family, friends, and learning. Members of WHS’s Guidance Staff and Crisis Response Team will be available to meet with students as they return to school on Monday and over the coming days and weeks. In addition, Principal Chisum will address the student body with a video message. Families are asked to contact the school if they feel their child is in need of additional assistance.
