Via The Volokh Conspiracy, a remarkable story from Florida:

While Ronald Earl Williams was stabbing his wife to death, he unknowingly created a key piece of evidence that could only exist in a wireless age.

Williams somehow activated his cell phone, which then called his wife’s cell phone while he was killing her, Assistant State Attorney Walter Manning told a jury on Tuesday.

The voice mail recorded the killing — with Williams threatening to kill his wife, and Mariama Williams screaming in terror — during the attack in their St. Petersburg home.

The recording could help jurors decide whether to convict Ronald Williams of first-degree murder and whether to recommend the death penalty. From the looks on jurors’ faces Tuesday, just listening was painful.
