According to charging documents obtained by Las Vegas Now, Haig's fingerprints were found on armor-piercing bullets in Paddock's hotel room, where the gunman shot and killed 58 people attending the Route 91 Harvest Festival in Las Vegas on Sunday, October 1.
The DOJ's release claims that Haig told investigators that while he does reload ammunition, he does not sell it to customers and that none of the ammunition recovered from the shooting scene would have toll marks from his reloading equipment.
An Arizona man who sold ammunition to the gunman in the deadliest mass shooting in modern US history has been charged with manufacturing armor-piercing bullets. The court has set February 15 for a preliminary hearing.
If found guilty, he can fail jail-term up to five years. Haig's identity emerged by mistake after his name was not redacted in court documents. Investigators were in touch with Haig shortly after the shooting. Haig did not have a license to manufacture the weaponry, but sold such ammunition in Nevada, Texas, Virginia, Wyoming, and SC, according to business records. Had he used it, Howard said, even relatively low-quality cellphone video would have shown the very bright projectile trajectory. "I had no way to see into his mind".
Federal officials declined or didn't immediately respond to requests for comment.
Haig, who has closed his ammunition business, said he has received unwanted media attention and death threats since his name was released.
When Haig asked Paddock what he planned to do with the 720 rounds, which were surplus military tracer bullets, Paddock reportedly responded by saying he was planning on going to the desert to "put on a light show" with friends.
Victor said police found his client's name and address on a box that Paddock had - a box that Haig gave him to carry the tracer rounds he had bought.
Haig's lawyer said they held the news conference in a bid to protect his reputation after he was revealed earlier this week to be a "person of interest" in the investigation.
Later Friday, he appeared in federal court in shackles with his lawyer, Marc Victor.
In response to a question from CNN in January, the Clark County sheriff, Joe Lombardo, said federal authorities are investigating a person in the case. The product that I sold him had absolutely nothing to do with what he did.
"This was a routine transaction to purchase a routine type of ammunition that is available in many different retail outlets throughout the state of Arizona", the attorney said. He says he is only a merchant and the government should not have released his name.
Speaking of the bullets which contain a pyrotechnic charge that illuminates the path of fired bullets, Haig said, 'You would have seen red streaks coming from the window'.
