"I'm not comparing Mr. Nelson to the Alzheimer's patients I see," said Psychologist Robert Ouaou. "But that's similar to what we see in people with Alzheimer's. The same part of the brain is affected."

ORANGE COUNTY, Fla. — A doctor took the stand to explain to the jury that Nelson has problems with executive reasoning after examining his brain and finding a frontal lobe injury.

Technical issues derailed some of Monday's testimonies that were supposed to take place over Skype, so the judge sent the jurors home.

Scott Nelson admitted to the crimes on the stand during last week's trial. Nelson testified last that he "wasn’t planning on killing" Fulford.

The courtroom fell silent Monday when Fulford's husband, Robert Fulford, took the stand.

"We all know how Jenny died, but I'd like to share a little about how she lived," Robert Fulford said, later showing pictures of him an his wife.

A medical examiner later took the stand to tell the jury that it took Jennifer Fulford five minutes to bleed to death.

Scott Nelson's attorneys presented evidence Monday to try to keep him off death row.

Lawyers spent the morning telling the jury about all the people who have been mean to Scott Nelson throughout his life and how it affected him mentally.

Prosecutors said they will discount a mental illness diagnosis.

A death sentence requires a unanimous decision by the jury.
