In the inventory of items seized is "5 jumper wires" allegedly used to bypass the mechanism that controlled the deployment and release of the ride's safety harnesses.
Prosecutors allege ride owner Joshua Macaroni, 32, deliberately tampered with the ride's safety mechanism.
The search warrant alleges Mararoni and ride operator Tim Tutterow, 42, were aware of the problem Oct. 21 - days before the ride malfunctioned on Oct. 24. That's when the Vortex ride restarted as riders were getting off, sending people flying to the ground - including a family of three.
Macaroni's lawyer has said he was not at the fair of the time of the accident, and they couldn't see how he was involved. However, prosecutors said that before a Labor Department ride inspection, Macaroni told Tutterow to make sure no one was looking while he put in the jump wires.
Both Macaroni and Tutterow are charged with three counts of felony assault with a deadly weapon.
The release of the search warrant Thursday signals an end to the on-site investigation at the State Fairground and will effectively allow the owner to take the ride back to Georgia.
Meanwhile, the Wake Forest family that was injured - father Anthony Gorham, mother Kisha Gorham, and 14-year-old son Justen Gorham - have been recovering from their severe injuries.
At last report, Kisha and Justen had been released from the hospital, but Anthony was still being treated for severe brain, skull, neck, and spinal injuries.
A fundraiser has been set up for their mounting hospital bills.
