>> Just a week after the deadliest mass shooting in US history, the FBI on Monday will be releasing transcripts of calls placed to 911 dispatchers by the Orlando gunman during his rampage. The shooter, Omar Mateen, who killed 49 people before dying in a gun fight with police is said to have repeatedly paused during his three hour siege to call 911 and post messages on line from inside the Pulse nightclub, professing his support for Islamist militant groups.

Lynch said investigators are focused on building a complete profile of Mateen, a US citizen of Afghan descent who has been described by officials as self-radicalized.>> We're trying to uncover everything we can about this killer's motivations, what led him to this particular place, this particular club.

Sunday nearly 50,000 people gathered at the park in Orlando for a memorial vigil. Lynch will a meet with survivors and investigators in Orlando on Tuesday.
