(CNN) An Arizona man described as a person of interest in police search warrants following the Las Vegas mass shooting in October says he sold ammunition to attacker Stephen Paddock.
Douglas Haig told CNN affiliate KNXV on Tuesday that he was identified as a person of interest following the massacre that left 58 people dead at a country music festival outside the Mandalay Bay Resort and Casino.
Douglas Haig told KNXV he'll answer questions at a news conference Friday.
"I'm the guy that sold ammunition to Stephen Paddock," Haig told the TV station outside his home in Mesa. He declined to provide additional details, saying he will answer questions at a news conference Friday with his attorney.
Haig did not respond to CNN calls Tuesday evening. Las Vegas police officials told CNN the department cannot comment on Haig or any names, and referred CNN to federal authorities.
Haig told CBS he sold Paddock 720 rounds of tracer ammunition from a business he ran out of his house until a few months ago.
"He told me exactly what he wanted. I handed him a box with the ammunition in it and he paid me and he left," Haig told CBS, adding that he didn't detect anything odd about Paddock. "He said he was going to go put on a light show. I can't remember if he said for or with his friends. But that's what he did say."
A judge in Nevada unsealed search warrant records Tuesday that mentioned a second person of interest in the case but redacted the name. The killer's girlfriend, Marilou Danley, had been identified earlier as a person of interest but has since been publicly cleared.
The Las Vegas Review-Journal identified Haig on Tuesday as the second person of interest, which led to his confirmation to reporters. While Danley and Haig were named by law enforcement as persons of interest in search warrant affidavits, neither has been charged with a crime.
Days after the shooting, Haig told Newsweek that agents from the federal Bureau of Alcohol, Tobacco, Firearms and Explosives interviewed him but said he had nothing to do with the crime.

Douglas Haig is also the name of a business associate on a website called Specialized Military Ammunition. The website describes itself as "your source for premium, MILSPEC, tracer and incendiary ammunition in popular military calibers," including ammunition that "ignites diesel and kerosene."
It's unclear whether it's the same person. A message posted on the website says it will be closed indefinitely.
"Check back to see if/when we are up and running again," the undated message says.
