LANCASTER, Pa. -- Charles Carl Roberts IV had "absolutely no emotion" in his voice as he told 911 operators he would kill a group of Amish girls if police didn't leave in "two seconds," Lancaster, Pa., District Attorney Don Totaro said.

Interactive: U.S. School Shootings

Totaro described the voice of the killer just moments before he opened fire on five girls, then committed suicide on Oct. 2 at an Amish schoolhouse in Nickel Mines, Pa.

He described Roberts as having a calm, flat voice as he refused an operator's request to hold on and be transferred to the Pennsylvania State Police. Roberts repeated his two-second demand, then hung up.

The district attorney transcribed the 911 calls from the day of the killing. He said there's no indication that anyone else in the school can be heard.

But the public won't actually hear any of it. The district attorney's office refused to release the audio, with one assistant prosecutor saying the contents of the tape would be "salacious."

Other transcripts include a call from Roberts' wife, expressing repeated concern he would kill himself, and a farmer's call initially reporting a man with a gun in the school. That farmer was Amos Smoker.

In some cases where the transcript indicates the line went dead, it is because the call was transferred to state police and was not recorded by Lancaster County, the prosecutor's office said.
