VICTORIA Members of the Oak Bay High School community are expressing their condolences after a teenager died unexpectedly over the weekend. In a letter sent to families Monday, Oak Bay principal Tom Aerts said that St. Michael s University School student Harrison Helliwell died on Sunday. The Grade 10 student went to Oak Bay High last year, and was expected to return to the school for Grade 11. Since he previously attended Oak Bay High, the school said he likely had many social connections with current students. The school provided some advice for families who may be affected by the unexpected death. The school suggests that parents listen to children and make time for them as they grieve, try to maintain a regular routine and watch for physical signs of grief, such as headaches, loss of appetite, anxiety or sleep disturbance.
