The main witness in the death penalty case against an Orange County man accused of murdering an 83-year-old woman took the stand Tuesday, the second day of the trial.

Janet Gutierrez testified that Juan Rosario asked Elena Ortega for money the night the woman was beaten, robbed and then left to die in her burning home in 2013.

Gutierrez was on the stand Tuesday morning. She said at the time that she told Rosario she didn't have any money. Later that night, Gutierrez said, Rosario came home with money and jewelry and was covered in blood.

"He told me he had to kill her because she saw his face and his fingerprints were everywhere," said Gutierrez, who is Rosario's ex-girlfriend.

Gutierrez said she helped Rosario cover his tracks.

Defense attorneys said Gutierrez is a convicted felon who is an unreliable witness. They said she's not credible because she has changed her story several times since coming forward. Attorney Roger Weeden said Gutierrez sent Rosario love letters and visited him in jail. 

Gutierrez told Weeden on the stand that she was promised immunity.

"What does that mean?" Weeden asked.

"That I couldn't be charged for anything that I told them," Gutierrez responded.

The judge admonished the defense Tuesday, however, saying attorneys were not turning over discovery to the state. Judge Leticia Marques said Rosario's attorney had violated the discovery rules three times. 

If Rosario is found guilty, jurors will make their recommendation in May or June if he should get the death penalty.

This is the first death penalty case tried in Orange County after Gov. Rick Scott took almost two dozen first-degree murder cases away from State Attorney Aramis Ayala.

Ayala said earlier this year that she will not seek capital punishment as a sentence while she is in office.
