He's confessed to firing multiple shots at two teenage intruders. He's got videotape of them outside his house before they broke in and an audio recording of their gruesome killings as they walked the stairs to his basement on Thanksgiving Day.
And according to prosecutors, he made chilling comments to the teens as they lay dying: "You're dead" to Nick Brady, 17, and "bitch" to Brady's cousin Haile Kifer, 18.
With so much evidence working against Little Falls homeowner Byron David Smith, who posted bond and got out of the Morrison County jail Tuesday, how does an attorney go about defending him on second-degree murder charges?
"I might withdraw," Minneapolis defense attorney Joe Friedberg quipped.
Attorney Steve Meshbesher, who represents the 64-year-old retired a U.S. State Department employee, declined Tuesday to discuss his legal strategy or make his client available to talk about what happened.
"I'm not going to turn this into a zoo," he said. "There's been too much media attention already. This is about me defending a person who is very defendable, and I have every intention of doing that in the courtroom."
Meshbesher said he will spend the coming weeks scrutinizing everything prosecutors have gathered in building their case against Smith, who once set up security systems at U.S. embassies across the world.
In the meantime, colleagues said Tuesday that Meshbesher faces a formidable challenge in defending his client, who lived alone in a home on the edge of Little Falls and said he had been the victim of multiple break-ins.
