Input: Even before her boyfriend was named as the man responsible for the deadliest mass shooting in modern US history   Marilou Danley  knew something was up.
An hour before Las Vegas cops released Stephen Paddockâs name   Danley  deleted  her  Facebook account  according to newly released documents about the Oct. 1 mass murder of 58 people attending an outdoor country music concert on the Strip.
 Danley  was traveling in the Philippines when Paddock unleashed the bullet barrage from the 32nd floor of the Mandalay Bay resort.
 Danley  was âadamant that  she  had no prior inclination of Paddockâs intentions to conduct the attack â says an FBI agentâs affidavit.
But the documents suggest  Danley  moved quickly after the shooting to obscure  her  relationship with the 64-year-old Paddock.
At 2:46 a.m.   her  account was deleted  said the documents.
Output:
Vegas shooterâs girlfriend may have known something was up
