[1] The car was filled over capacity with people from outlying areas en route to Tacoma's 4th of July parade.
As the car descended a hill down Delin Street towards a sharp curve, it became evident the motorman would not be able to slow down sufficiently, and passengers began to jump off.
[2] Residents and bystanders in the area heard the crash and hurried to give aid.
Ultimately, the accident was blamed on the motorman, F. L. Boehm, for allowing the car to reach excessive speed, with the jury also finding that Tacoma Railway and Power Company was criminally negligent for assigning Boehm to an unfamiliar route and for improper maintenance of its cars, rails, and the unsafe grade.
[2] The Tacoma Railway and Power Company stopped using the trestle shortly thereafter and it was torn down in 1910.
