Police have made public 22 more video clips of body-worn camera footage showing gun-wielding officers encountering tourists on Las Vegas Boulevard after the Oct. 1 shooting that killed 58 people and injured hundreds.

Wednesday's public records release provided images of officers with rifles in parking lots, stopping motorists, advising hotel residents which properties were open and searching empty casino floors in the hours after the massacre.

Sheriff Joe Lombardo on Aug. 3 declared the police investigation finished, with no motive found for the deadliest mass shooting in modern U.S. history. An FBI final report is expected by the end of the year.

Officials say the shooting from a Mandalay Bay resort suite into a Route 91 Harvest Festival concert crowd was the act of a lone gunman and not a broad conspiracy.

A doctor accused of improperly looking up prescription records of the dead gunman after the Oct. 1 mass shooting on the Las Vegas Strip will invoke his constitutional right against self-incrimination at an upcoming Nevada State Pharmacy Board disciplinary hearing.

Lawyer E. Brent Bryson said Wednesday that Dr. Ivan Goldsmith is the focus of a "witch hunt" for the source of a newspaper report about gunman Stephen Paddock's prescriptions in the days after the deadliest mass shooting in modern U.S. history.

Bryson accused board officials of "grandstanding to try to influence public opinion about Dr. Goldsmith, to paint him in a negative way before the hearing."

Nevada State Prescription Board attorney Brett Kandt denied the grandstanding claim and declined comment about the complaint against Goldsmith.
