As C-Tran awaits the outcome of a police investigation into this month’s fatal bus accident in downtown Vancouver, this week it heard questions about the incident from a man connected to another recent tragedy.Vancouver resident David Sale addressed the C-Tran board Tuesday with some of his own safety concerns — including the locations of bus stops and crosswalks near the scene of the Dec. 2 accident.Sale’s own daughter, Danielle, was one of two people killed in a 2010 accident involving a TriMet bus and a group of pedestrians in Portland. Three others were injured. Sale has since advocated for improved safety around public transit, and expressed the same wish this week.“I am here to help,” Sale said, “and not hurt.”Just before noon on Dec. 2, a No. 4 C-Tran bus struck and killed Margaret McCluskey, 88, at the intersection of Washington and Eighth streets. The bus was turning left from Eighth onto southbound Washington when it hit McCluskey in the crosswalk, according to police. The driver, Al Purvis, was placed on paid administrative leave — which is standard C-Tran procedure — until the investigation is over.Vancouver police haven’t finished that inquiry yet, said spokeswoman Kim Kapp. C-Tran will conduct its own review when the police report is released.
