A variety of conspiracy theories have sprung up around the Charlottesville car attack. As usual there were suggestions that the attack was faked. One piece of "evidence" was the car license plate on the car driven by James Alex Fields Jr, an Ohio plate reading GVF 1111. Video of his mother, Samantha Bloom, shows a similar number GVF 1122. Conspiracists suggest this is an unusual looking number, and it's unusual that two family members would have such similar numbers.
Some claims are obviously ridiculous, like the idea that the "G" stands for "Government". The license plates are standard Ohio plates. Both numbers are correctly registered to the cars shown and show up on public info sites like SearchQuarry. But because their information comes from scraping public source it's not always up to date.
The name returned (Jerome V....) is not that of the driver, it's the name of the previous owner of the car. This is tied to the VIN number, and not the license plate. Incorrectly using this information led to Jerome and his family having to leave home due to death threats:
The other car however is listed as being registered to Samantha Bloom.
Searching for other license plates like GVF 1112, 1113 etc return perfectly normal results.
The simplest explanation here is that mother and son re-registered their cars at the same time when moving into Ohio from Kentucky.
Since they were registered at the same time they got numbers that were very close together. The family appears to have moved from Florence, Kentucky, into Ohio. (Florence, KY is essentially a suburb of Cincinnati, OH, so it's a short move over the Ohio River and you have to re-register your car)
