According to the video from Rudys show, a drunken Hunter dropped off the computers to be repaired. It is standard procedure to download contents while repairing. Hunter came back and dropped something else off as well. When the repairman later contacted him to come get his stuff, he got no answer. He reached out several times to Hunter but he never came back.
After the time specified in the written repair agreement ran out, the equipment and contents became the property of the shop owner. He then examined the contents and realized he was in possession of some illegal stuff. He contacted various authorities several times, even the FBI, but none responded. He grew more worried and finally gave the information to Rudys lawyer.
Rudy says they have only had time to go through about a quarter of the evidence. So far there are four main players and four areas of illegality. Rudy says its classic RICO and that they are really the Biden crime family.
I forgot to mention that Rudy said one of Hunters business associates has verified the contents of the laptops and the emails are true.
