The defendant had already been convicted of manslaughter for killing his neighbor by the jury, according to a New York Criminal Lawyer.
One of the key concepts in the case, included prominently in the jury instructions, was “prudence”. Specifically, they were asked to determine whether the defendant acted in prudence when it came to the victim.
The jury foreperson used his iPhone to access an Encarta and look up the word “prudence”, during a break from deliberations. He then shared this information with the other jurors, sources told New York Criminal Lawyers.
