JACKSONVILLE, Fla. -- Jurors asked a fourth question Thursday of Judge Russell Healey, having deliberated 10 hours already in the first degree murder trial of Michael Dunn. Deliberations will resume at 9 a.m. Friday.

The five men, seven women jury wanted to know the date of a letter Dunn sent to his family and friends. The typed letter was introduced into evidence and described Dunn's recollection of events the night of Nov. 23, 2012.

According to Dunn's testimony under cross examination by Prosecutor John Guy, letter was written in June 2013.

When told, a couple jurors nodded, as if they knew and expected that answer.

In other matters, the judge said he planned to keep the four alternates sequestered through tomorrow, in case they were needed. He agreed to let the jury continue deliberating until 6:15 pm, and then bring them back at 9 am assuming no verdict is reached.

You can watch live coverage of the verdict on at firstcoastnews.com and on twitter @FCN2go.

First Coast News has poured over Dunn's jail letters and came up with two possible letters and posted them below. Both letters are heavily redacted.

The first letter, written to his fiancée Rhonda Rouer, contains a coded message in the first paragraph. First Coast News decoded the message and we believe it says:

"Three things that are certain in this life: Death, taxes and that the press will get it wrong."

In the second letter below, also written to Rouer, he recounts what happened the night of the shooting and reiterates "...there was a weapon."
