The state asked Zimmerman's wife about the time her husband went into hiding after shooting Martin.
"I have not been with my husband since he's been in hiding," she said, adding that she talked to him every day, even when he left Florida.
Shellie Zimmerman said she's received hate mail since the fatal shooting.
"Anything that happens to my husband is a personal threat to me. "I have received hate mail," she said, adding that no direct threats to her were contained in the letters.
George Zimmerman's father, Robert Zimmerman Sr., was then questioned by O'Mara over the phone and said that he's lived in Central Florida for more than five years.
Zimmerman Sr. said he's a disabled veteran who doesn't have a lot of money or assets. He later told the state that his son has a car but didn't know if he owns it.
"I've never known him to be violent at all, unless he was provoked, and then he'd turn the other cheek," said Zimmerman Sr. when asked about his son's temperament.
De la Rionda asked Zimmerman's father about his son's prior arrest.
"I knew of an incident involving alcoholic beverage control officers in plain clothes," Zimmerman Sr. said, adding that he never read the arrest report. "I believed (my son) because he's been honest his whole life."
De la Rionda also asked about George Zimmerman's interest in law enforcement.
"He's always been interested in criminal justice," said Robert Zimmerman Sr., confirming that his son majored in the subject in college, and later adding, "At some point in his life he wanted to be a magistrate or a judge. ... "He wanted to be able to help somehow."
He was then asked about having contact with his son since the shooting.
"I've had fairly limited contact with my son since his head was beaten," Robert Zimmerman Sr. said. "His face was swollen quite a bit. He had a protective cover over his nose, his lip was swollen and cut, and there were two vertical gashes on the back of his head."
George Zimmerman's mother, Gladys Zimmerman, also testified at the hearing, saying she stays in frequent contact with her son and his wife.
"We have received a lot of threats," she said after being asked about her family's safety.
Zimmerman's mother said her son is protective of children and the homeless, adding that he was recognized by the Sanford mayor.
"In 2010, he found out a homeless person was beaten in Sanford, and he organized the community to ask for justice," she said, adding that he posted flyers throughout town and attended churches to raise awareness about the case.
She said her son also mentored two African-American students, a 14-year-old boy and his sister, in Orlando.
Gladys Zimmerman told the court that she would plead for her son to be careful while traveling to meet with the children.
"Please don't go, it's too dangerous," she said, adding that her son replied, 'Mom, if I don't go they don't have nobody.'"
The state did not call any witnesses.
Dale Gilbreath, a state investigator and one of two working the Martin shooting case, was called to the stand by O'Mara and questioned about the probable cause affidavit that he signed.
O'Mara asked Gilbreath about the word "profiling" that was listed in the affidavit.
"When talking to the police dispatcher, he identified (Martin) as suspicious," said Gilbreath, who also said that he has never spoken to Zimmerman.
Gilbreath further discussed the night of the fatal shooting.
"Zimmerman said he didn't want (Martin) to get away because they always get away," he said.
