Las Vegas police are making public their final report on the shooting that killed 58 people and injured hundreds last year at a country music festival and was the deadliest mass shooting in modern U.S. history.

Clark County Sheriff Joe Lombardo announced he will provide reporters with the results of 10 months investigating the Oct. 1 shooting on the Las Vegas Strip, though it's unclear if police will have any answers as to why gunman Stephen Paddock shot from a Mandalay Bay hotel room into a concert crowd of 22,000 people.
 
The sheriff and the top FBI official in Nevada have said that they believe the shooter acted alone and it was not terrorism and that they may never know his motive.
 
Police have released 13 batches of investigative documents, 911 audio, police reports, witness statements and video over the last three months.
