It isn't that the 42-year-old man had done anything wrong to infuriate Elytte Barbour and his wife.
The couple – married three weeks - just wanted to kill someone together, police said.
And Troy LaFerrara happened to be the unlucky one.
The Barbours are accused of luring LaFerrara through a sex ad on Craigslist, and stabbing and strangling him to death.
Barbour told police he and his wife had tried to kill others. But the plans didn't work out.
"So," police said, "they continued to try to find someone."
