Julie Schenecker will not testify in her own defense for her double-murder trial.

The defense rested their case Tuesday. Court resumes Wednesday morning at 8:30 a.m. with the state's rebuttal.

The ex-husband of Schenecker was called to this stand again Tuesday, this time by the defense, and he testified for about four hours in the New Tampa woman's murder trial.

Through tedious questioning on direct and cross examination, Parker Schenecker gave a comprehensive timetable of their relationship, starting when they met while playing volleyball and continuing all the way until, authorities say, Julie Schenecker shot and killed their teenage children, 16-year-old Calyx and 13-year-old Beau.

During the afternoon, the defense called Dr. Wade Myers, a forensic psychologist, who, like two medical experts Monday, testified about the profoundness of Julie Schenecker's mental illness. All three experts said Schenecker was insane when she shot the children.

Julie Schenecker is charged with two counts of first-degree murder and has pleaded not guilty by reason of insanity. To be found criminally insane under Florida law,  a jury would have to find that either didn't know what she was doing when she killed her children or didn't understood that it was wrong.

Myer said he diagnosed Juli Schenecker as bipolar with psychotic disorders, although he considered a diagnoses of schizoaffective disorder because she often lost her train of thought in mid-sentence. He said that at one time, Schenecker was on 10 different medications with psychoactive effects.

The psychologist told him that she believed that if she left her children behind, they would be sexually abused.

"She was insane at the time she shot her children," Myer said.

Defense attorney Jennifer Spradley questioned Parker Schenecker about his and Julie's Army travels, courtship, marriage and the birth of their children.

Parker Schenecker also testified about Julie's mental state, alcohol use and a November 2010 traffic crash. He said he told Julie after the crash that she would no longer be driving their children around and that she had to go to rehab and needed to "re-assimilate herself into the family."

He said the relationship between Julie and Calyx began to deteriorate around the time the teen left middle school and started King High School in Tampa.

Of his frustrations with the strained relationship between his wife and daughter, Parker said he told family members: "Have any of you ever lived with a 50-year-old who has the judgement of 10 year old?"

Defense attorneys portrayed Parker Schenecker as a man unfamiliar with mental illness and unable to comprehend his wife's bipolar disorder. He said he didn't monitor her many medications and didn't know she had a gambling problem until after the children's death.

On Monday, Dr. Edra Solomon said she spent about a total of 20 hours with Schenecker in the weeks after her arrest on Jan. 28, 2011 murders and said she based her diagnosis on the time spent with her a review of her medical records. Solomon said Schenecker had "bipolar 1 with psychotic features."

Also, Dr. Michael Maher testified that Schenecker was prescribed up to 10 different anti-psychotic, anti-depression and mood-stabilizing medications for her bipolar and depression disorder.

If found guilty, Schenecker could face life in prison.
