Los Angeles (AFP) - An Arizona man was charged Friday with making armor-piercing ammunition without a license and selling it to the Las Vegas gunman whose October killing spree left 58 concert-goers dead.
Stephen Paddock, 64, killed himself after the rampage carried out from his hotel suite on Las Vegas' famed Strip on October 1 -- the deadliest mass shooting in recent US history.
Douglas Haig, 55, is charged with one count of conspiracy to manufacture and sell armor-piercing ammunition and was released on bail pending a preliminary hearing on February 15 in Phoenix.
He faces the maximum penalty of five years in prison, and possibly a $250,000 fine, if convicted.
Paddock allegedly came to Haig's home in Mesa, on the outskirts of Phoenix, in September last year to buy ammunition.
Haig had previously operated "Specialized Military Ammunition," an Internet business selling armor-piercing bullets, some of them high explosive, according to a statement from US Attorney Dayle Elieson of Nevada.
Records show he had done business in Nevada, Texas, Virginia, Wyoming and South Carolina despite having no license to manufacture armor-piercing ammunition.
Haig told investigators he reloads ammunition but does not offer reloaded cartridges for sale, and none of the rounds recovered in Las Vegas crime scenes would have tool marks consistent with his reloading equipment.
But Elieson said forensic examiners had recovered reloaded, unfired .308 caliber cartridges in the shooter's hotel rooms bearing Haig's fingerprints.
Armor-piercing ammunition recovered inside the shooter's rooms had tool marks consistent with Haig's reloading equipment, the statement added.
Police believe Paddock, a wealthy retired accountant and compulsive video poker player who took Valium for anxiety, had lost a significant amount of money before his killing spree.
Technicians scouring Paddock's computer found searches for firearms and elite police response teams, as well as "numerous photos of child pornography," Clark County Sheriff Joe Lombardo said last month.
Paddock had stockpiled an arsenal of firearms in his room at the Mandalay Bay hotel before he rained fire down on a country music festival where about 22,000 people had gathered.
In addition to the 58 dead, hundreds were wounded. They included 422 people who sustained wounds related to gunfire.
