Jurors hear chilling audio of shootings in Little Falls murder trial

The jury in the Byron Smith murder trial listened to a chilling audio recording of the fatal shootings of two teenagers who had broken into Smith's Little Falls house in November 2012.

Smith, 65, is being tried on first-degree murder charges for killing Nick Brady, 17, and Haile Kifer, 18, after they broke into his home on Thanksgiving night 2012.

Jurors heard about 15 minutes of the recording Tuesday, the second day of testimony, and on it they heard the voices of the teenagers as they were surprised and shot to death by Smith, the Star Tribune reports.

At various points on the tape, Smith can be heard saying “you’re dead,” "you're dying," and “oh sorry about that,” and calling Kifer a “bitch,” according to FOX 9.

Family members of Brady and Kifer sobbed as the audio played, but jurors displayed little emotion, FOX 9 reports.

Smith set up video and audio recording devices in his home after repeated break-ins over several months, and according to his attorney, he wore a holster and pistol in his house because he was afraid intruders would come back.

Smith has argued that he fired at the teens while defending his home from intruders, which is legal in Minnesota, but prosecutors say he crossed a line when he continued to fire at the unarmed teens after they were injured.

The two teenagers were linked to other area robberies. Authorities said a car linked to Brady and Kifer contained prescription drugs stolen from another house. Court documents from another case show Brady had previously burglarized Smith’s property at least twice.

If convicted of first-degree murder, Smith, a retired security engineer for the U.S. Department of State, faces life in prison.
