Input: Consider Input: Undersheriff Kevin McMahill of the Las Vegas Metropolitan Police Department  said at a press briefing the department has been exploring every aspect of Paddock's life  from birth to death  in search of an explanation.  He  said they have looked into details regarding Paddock's personal life  political affiliations  social behaviors  and economic situation â but answers remain evasive.
"We have been down each and every single one of these paths trying to determine why. Trying to determine who else may have known of these plans  " McMahill  said  adding that the rumors and speculation that have abounded in the wake of the shooting have been unhelpful to their investigation.
"In the past  terror attacks or mass-murder incidents  motive was made very clear  very clear in most of those cases by a note that was left  by a social media post  by a telephone call that was made  by investigators mining computer data  " McMahill  said. "Today in our investigation  we don't have any of that uncovered. I wish we did. We will and are continuing to investigate with great tenacity and hope to arrive at an answer."
 McMahill  also shot down several prevalent rumors that have circulated throughout media reports  telling reporters that they are confident no second shooter was in the room with Paddock during the attack.  He  said  he  could not  however  confirm whether any other people knew about Paddock's plans to carry out the shooting.
 McMahill  also said investigators do not believe anyone other than Paddock accessed  his  suite before the attack  despite reports suggesting a room key was used to enter  his  suite while Paddock's car was outside the hotel's parking garage.
 He  also said the Tannerite â an explosive powder used for long-range target practice â that was recovered from Paddock's home was not in a condition to be used in an IED  as others had questioned.  McMahill  said  it  was also unclear what Paddock intended to do with the tannerite.
Investigators are  however  "keenly interested" in Paddock's medical status at the time of the shooting   McMahill  said. The Las Vegas Review-Journal recently reported that Paddock had been prescribed the anti-anxiety drug diazepam â also known by its brand name  Valium.
"It's really imperative that the listening public have a very clear understanding that there are still a number of people out there that know that something looked out of place  " McMahill  said. "Someone may have been acting suspiciously that night  or in the years prior  the months prior. Somebody that may have seen something or know something."

Output: Las Vegas motive of Stephen Paddock still unclear police say

Input: Consider Input: The New Yorker cut ties with  Ryan Lizza  over sexual misconduct.
 Lizza  was one of the magazine's most prominent journalists.
 He  said  he  was "dismayed" at The New Yorker's decision.
The New Yorker on Monday announced that it had cut ties with  the high-profile political reporter Ryan Lizza  because of what  it  characterized as "improper sexual conduct."
"The New Yorker recently learned that  Ryan Lizza  engaged in what we believe was improper sexual conduct " the magazine said in a statement. "We have reviewed the matter and  as a result  have severed ties with  Lizza . Due to a request for privacy  we are not commenting further."
CNN  where  Lizza  is a political analyst  also said on Monday that he would not appear on the network while it investigates.
"We have just learned of the New Yorker's decision " a CNN representative said. " Ryan Lizza  will not appear on CNN while we look into this matter."
In a statement   Lizza  said  he  was "dismayed that The New Yorker has decided to characterize a respectful relationship with a woman I dated as somehow inappropriate."
But the lawyer representing an alleged victim of  Lizza 's misconduct pushed back on his statement.
"Although she desires to remain confidential and requests that her privacy be respected  in no way did  Mr. Lizza âs misconduct constitute a 'respectful relationship' as  he  has now tried to characterize it " Douglas Wingdor said in a statement. "Our client reported Mr. Lizzaâs actions to ensure that he would be held accountable and in the hope that by coming forward she would help other potential victims."
 Lizza  has for years been one of the most high-profile political journalists in America  writing lengthy profiles about former President Barack Obama and others.
Earlier this year   Lizza  reported on an expletive-filled conversation he had with Anthony Scaramucci  President Donald Trump's communications director. Days after the report  Scaramucci departed the White House; he had been in the position for one week.
