As a gunman attacked Newtown, Ct.’s Sandy Hook Elementary School last December, staff members inside relayed their mounting horror to police dispatchers who calmly urged them to take cover and protect the students, according to emergency recordings released yesterday, the Wall Street Journal reports. The seven calls totaling about 25 minutes produced little new information on the assault that took the lives of 20 students, six staff members and the shooter, except to serve as a fragmentary, moment-by-moment record of the shooting that stunned the nation and set off fierce debate about gun violence. The release of the tapes concluded a months-long legal dispute between the Newtown Police Department and the news media. The calls include those made by a teacher, a custodian and another adult who said she was inside the school. About half the recordings center on dispatchers’ interactions with a school custodian who stayed on the line to tell officials what he was seeing and hearing. The release of the emergency recordings came a week after a prosecutor’s report said shooter Adam Lanza’s motive may never be known.
