At 2:35 a.m., Mr. Mateen called 911 himself to claim responsibility for the attack, and declared allegiance to the Islamic State, the F.B.I. At 2:51 a.m., when Mr. Mateen was on the phone with a police negotiator, the F.B.I. Emergency calls from inside the Pulse nightclub poured into the Orlando police in the early morning of June 12 from panicked and wounded revelers reporting the bloody scene as it played out. A few times, callers went silent or their calls went dead, leaving dispatchers no way of knowing if they were still alive. “SWAT breached,” the log says at 5:02 a.m. At 5:15, as the officers traded gunfire with Mr. Mateen, it notes, “Shots fired north bathroom,” and less than a minute later, “Subj down.”An entry just before 5:18 a.m., using a police term for armed, states, “Bad guy down strapped.”
