Three months before killing 58 people and wounding more than 500 in Las Vegas last October, the gunman behind the deadliest mass shooting in US history sent emails discussing buying bump stocks, which can make semiautomatic rifles fire hundreds of rounds a minute, media reports on unsealed search warrants showed.
Bump stocks believed to be used in the massacre were found in the 32nd-floor hotel room from where Stephen Paddock fired down on a crowd
gathered on a Sunday night for the finale of a country music festival held on the Las Vegas Strip.
The details suggesting the attack may have planned months in advance were part of more than 300 pages of search warrants unsealed by a federal judge in Nevada on Friday, according to the Los Angeles Times, one of several publications that sought release of the documents.
The unsealed documents do not provide a motive for the killings, the Los Angeles Times reported.
