A few other horrifying details:
* Riders were restrained by Velcro straps. These frequently came loose. One rider broke several toes after his restraint came undone during a ride, forcing him to dig his feet into the corners of the raft.
* The brake system on the ride was completely nonfunctional when the boy was killed, and had been that way for several weeks. Evidence suggests that the park planned to delay maintenance until the park closed for the season.
