The Latest on the investigation into the deadliest mass shooting in modern U.S. history (all times local):

4:35 p.m.

The coroner in Las Vegas has started releasing redacted autopsy records about the 58 people killed in the deadliest mass shooting in modern U.S. history.

Records relating to the shooter, Stephen Paddock, are not being provided.

Clark County Coroner John Fudenberg (FYOU'-den-berg) said in December that all those victims were killed by gunfire.

The records were released after a public records lawsuit was filed by The Associated Press and Las Vegas Review-Journal.

Case numbers, names, ages, hometowns and racial characteristics are blacked out of the documents.

The release of the documents come on the eve of the four-month anniversary of the Oct. 1 shooting on the Las Vegas Strip that authorities say also left more than 800 people injured.

A lawyer for an Arizona man who sold ammunition to the gunman in the deadliest mass shooting in modern U.S. history says his client was disturbed that he didn't spot any suspicious signs about his one-time customer.

Attorney Marc Victor says Douglas Haig of Mesa had no reason to believe Stephen Paddock would carry out the Oct. 1 attack that left 58 people dead at a concert in Las Vegas.

Victor says Haig wishes he could have figured out the intentions of Paddock but defends the sale of tracer ammunition as legal.

Records identified Haig as a "person of interest" in the investigation, but officials haven't said whether he has been cleared or is under criminal investigation.

It's unclear if the ammunition Haig sold to Paddock was used in the shooting.

An Arizona man identified in court documents as a "person of interest" after the Las Vegas massacre says he sold ammunition to the gunman, Stephen Paddock, and says he had no idea what Paddock was going to do when he met him weeks before the shooting.

Douglas Haig tells "CBS This Morning" on Wednesday he sold more than 700 rounds of ammunition to Paddock. He says Paddock told him he was going to put on a "light show" with the tracer ammunition he purchased.

Haig says he talked to Paddock three times and that officials won't find any connection between the two.

He says he wonders, "What did I miss?" and "Why didn't I pick this up?" in his interaction with Paddock.

An Arizona man identified in court documents as a "person of interest" after the Las Vegas massacre says he sold ammunition to the gunman Stephen Paddock.

Douglas Haig says he met the gunman one time and he had been contacted by investigators earlier in the case.

Haig told The Associated Press on Tuesday night: "I am the guy who sold ammunition to Stephen Paddock,"

Haig did not release other details before walking into his home in the Phoenix suburb of Mesa.

A law enforcement official told The Associated Press in October that Paddock bought 1,000 rounds of tracer ammunition from a private seller he met at a Phoenix gun show. The official spoke anonymously because they weren't authorized to disclose case information.

Records show Haig owns Specialized Military Ammunition, LLC. The company's website says it sold tracer and incendiary ammunition but is now "closed indefinitely."
