Through a “Public Records” request, I was able to confirm the following deaths on Oregon tracks last year. (It should be noted, however, that Oregon is a relatively light-racing state, with but one regular track, Portland Meadows, and a handful of county fairs. In addition, Portland only had 31 days of live racing.)
4-year-old Really a Hero was euthanized after breaking in the 2nd at the Eastern Oregon Livestock Show (a 3-day fair) on June 7th. Equibase had the Donald Young-trained (and owned) mare “[going] wrong” and being vanned off.
4-year-old Demetrius was euthanized after the 10th at Portland Meadows December 2nd. The Margie Cantrell-trained gelding, too, was merely a “went wrong, pulled up, vanned off” on the chart. Two more ambulance-riders dead. This is horseracing.
