A criminal complaint says two unfired .308-caliber rounds found in gunman Stephen Paddock's room had Douglas Haig's fingerprints on them and tool marks from Haig's workshop. The bullets in the cartridges were classified as armor-piercing, the complaint says.
On October 19, the FBI searched Haig's home in Mesa, Arizona, and seized ammunition it says classifies as armor-piercing, the compaint alleges. Haig did not have a license to manufacture armor-piercing ammunition, documents say.
Haig, 55 appeared in court Friday and was released on this own recognizance with specific conditions that were not spelled out in court proceedings. He is due in court again February 15 for a preliminary hearing.
Haig has said publicly he sold tracer ammunition to Paddock, but he had no other dealings with him and never saw anything suspicious in their brief interactions.
Haig also said during a Friday morning conference at his attorney's office that he has received death threats after his name was revealed in newly released search warrant records this week.
Marc J. Victor, Haig's attorney, told CNN he had no comment.
