Nancy Bautista's fury over her husband's request for a divorce raged on even after she stabbed him the back, prosecutors said Wednesday.

On Aug. 27, 2007 — four months after the April 15 stabbing — she called police claiming that her husband had come to her apartment and stabbed her. They were estranged but not yet divorced at the time.

Bautista, 54, is on trial for attempted first-degree murder of Michael Bautista and making a false report in connection with the alleged Aug. 27 stabbing.

"The defendant's vendetta against him continued," said prosecutor Elly Peirson. "The defendant accused him of stabbing her in the back at her apartment. She is charged with false reporting for trying to frame him."

Michael Bautista, 56, an administrator for the Community College of Denver, testified Wednesday that he was at a Starbucks at Wadsworth Boulevard and Jewell that evening waiting for a woman he met on an Internet dating service. He said he waited for an hour and a half and then went home.

There, he said he received a call from Nancy Bautista's daughter asking why he stabbed her mother and telling him that the police were looking for him.

"I was totally surprised. I was amazed," he said.

Michael Bautista said he didn't know his where his wife's apartment was and didn't realize it was several miles from the Starbucks.

Defense attorney Michael Ferber suggested that Michael Bautista may have concocted his alibi at a Starbucks near his wife's apartment, while a juror asked whether Michael Bautista thought his wife had posed as the Internet date.

Michael Bautista said that he later suspected that because the woman's message contained wording that his wife commonly used.

Ferber also said that the couple was arguing over Michael Bautista's extramarital affairs — not a property list for their divorce — when Nancy Bautista, a nurse, stabbed her husband April 15, 2007, puncturing a lung.

Michael Bautista denied the alleged affairs under cross-examination by Ferber but admitted he sent a coworker an iTunes gift card because she was upset about breaking up with her boyfriend just before Valentine's Day 2007. He also sent her an email Feb. 7, 2007 that was found by his wife in which he said, "I know I'm crazy but you would make a great Valentine."

He denied that a sexual relationship developed between the two and denied sending emails to the woman that indicated they were intimate.

Prosecutors fought introduction of the emails.

"All this is going to do is make Michael Bautista look like a sleazebag and that's what they are trying to do," Peirson said.

Ferber also contended that Nancy Bautista threw glasses of champagne at her husband in an attempt to get away after he grabbed her and slammed her against the wall. Michael Bautista denied that.

Michael Bautista said he told his wife she had "become your mother" because "her mother was very controlling" and would berate her stepfather. "It seemed to me she did emasculate men fairly easily," he said.
