A court error publicly revealed the name of a man identified as a person of interest in the deadliest mass shooting in modern U.S. history.

Clark County District Court Judge Elissa Cadish acknowledged that a member of her court staff failed to black out the man’s name on one of 276 pages of documents released to news organizations including The Associated Press and Las Vegas Review-Journal.

After the error was recognized, lawyers for the news organizations were told to return the documents. The attorney representing AP and other media did so, but the other lawyer had already transmitted the documents and the Review-Journal published Douglas Haig’s name online.

Cadish later ordered the document not be published without redactions, but she acknowledged she couldn’t order the newspaper to retract the name.
