AVENTURA, Fla. -

Jury selection is under way in the trial of a man accused of killing his wife, whose defense attorneys have in the past blamed her death on an allergic reaction from a spray tan.

Forty-eight prospective jurors were brought in Monday in the trial of Adam Kaufman, who is accused of strangling his wife, Eleonora "Lina" Kaufman, 33, in their Aventura home in November 2007.

Adam Kaufman has denied killing his wife. Originally, his defense attorneys talked about the possibility that his wife may have had an allergic reaction to a spray-on tanning solution, causing her to choke and pass out.

Local 10 has obtained defense documents that indicate they will now introduce medical records and history that show Lina Kaufman had a virus known as CMV, which affects the heart, and that she suffered from fainting spells and headaches consistent with symptoms of cardiac insufficiency.

Judge Bronwyn Miller, prosecutors and the defense sought Monday to find out whether the potential jurors know about the case and whether they can be fair amid the media attention the case has gotten.

Jury selection is expected to take another day or two, and the trial is expected to last up to three weeks.
