Police responding to the deadliest mass shooting in modern American history may have witnessed gunman Stephen Paddock commit suicide inside his Las Vegas hotel room, newly unsealed documents indicate. The revelation contradicts previous police reports that the shooter was already dead when authorities arrived.

“As SWAT officers breached room 135, they observed Stephen Paddock place a gun to this head and fire one round,” one page of court documents released on Tuesday stated.

The account differs from that of Las Vegas Metropolitan Police Department Sheriff Joe Lombardo, who has said numerous times that officers found 64-year-old Paddock dead of an apparently self-inflicted gunshot wound when they breached his room at the Mandalay Bay Resort and Casino. Moments earlier, Paddock had shot 58 people dead from his shattered hotel room window.

On Tuesday, Lombardo told the Las Vegas Review-Journal he could not comment on the document because he had not read it. He referred requests to Police Sergeant Jerry MacDonald, who is expected to comment on Wednesday, the newspaper reported.

MacDonald had reported the SWAT team observed Paddock’s suicide while requesting a search warrant over the phone at 3 a.m. on October 2. Las Vegas Metropolitan Police Department spokesman Larry Hadfield told the Las Vegas Review-Journal MacDonald’s statement may have been inaccurate.

“During the early stages of the investigation, search warrants were completed with the known facts at the time. A search warrant is requested and information provided is preliminary and establishes the probable cause and reason to search the premise. The preliminary report released on January 19 is a more complete picture of the investigation as we know it now. As the investigation unfolds, we will have more accurate information available at a later date,” Hadfield said.

On January 19, police released an 81-page-long preliminary report detailing its investigation into the massacre containing two different passages, in which investigators said that Paddock was already on the floor when authorities entered his room.

“The Strike Team reported Paddock was down from an apparent self-inflicted gunshot wound to the head,” page 15 said.

“Team 2 encountered Paddock lying on the floor on his back. The officers believed Paddock had a self-inflicted gunshot wound,” investigators wrote on page 30.

The documents released on Tuesday following a court battle between police and media outlets also identified a second person of interest in the case, Douglas Haig, who in a previous conversation with Newsweek said he never knew “wacko” Paddock.

And in a bizarre revelation, the papers showed that police believed that Paddock had purchased a black vase full of fake flowers from Walmart four days before the shooting and brought them into his suite. Police requested a search warrant on October 31 to seize the flowers, the Las Vegas-Review Journal reported.

The Las Vegas Metropolitan Police Department did not immediately return a request for comment from Newsweek.
