CHANDLER, Ariz. (AP) -- The Latest on an Arizona man who sold ammunition to the gunman who carried out the deadliest mass shooting in modern U.S. history (all times local):

Las Vegas police wouldn't say whether armor-piercing ammunition was fired during the deadliest shooting in modern U.S. history after a dealer who sold it to the gunman was charged with manufacturing such bullets. Unfired armor-piercing bullets found inside the Las Vegas hotel room where Stephen Paddock launched the Oct. 1 attack had the fingerprints of ammunition dealer Douglas Haig, according to a criminal complaint filed in federal court in Phoenix. It said Haig previously ran an internet business, called Specialized Military Ammunition, selling armor-piercing bullets - some consisting of high-explosive and incendiary rounds - throughout the United States, but lacked a license to manufacture such ammunition. (Reuters) - An ammunition dealer who has acknowledged selling hundreds of rounds of tracer bullets to a gunman responsible for killing 58 people in Las Vegas was charged on Friday with conspiracy to make and sell armor-piercing ammunition without a license. Las Vegas police wouldn’t say whether armor-piercing bullets were used in the shooting but referred to a preliminary report saying some rifle magazines were loaded with armor-piercing ammunition. Haig, a 55-year-old aerospace engineer who sold ammunition as a hobby for about 25 years, was charged 35 minutes before holding a news conference where he said he didn’t notice anything suspicious when he sold the tracer rounds to Paddock. However, among the unfired rounds found in Paddock’s hotel room were two cartridges which forensic analysis determined were armor-piercing/incendiary ammo that had Haig’s fingerprints on them, the complaint states. From the complaint: "Significantly, forensic analysis determined that the two unfired armor piercing cartridges from Paddock's Mandalay Bay hotel room (bearing Douglas Haig's fingerprints) had toolmarks consistent with the reloading equipment recovered in Haig's backyard workshop during the October 19, 2017 search."
