In 1975, Carl Vergari appointed Pirro to the position of Assistant District Attorney of Westchester County, where she began her career by writing appeals and handling minor cases. In 1977, Pirro approached Vergari and requested that he apply for a federal grant for local district attorney's offices to establish bureaus that specialized in domestic violence. She hoped that Vergari would take advantage of potential funding as well as a 1977 change in New York law that moved many domestic violence cases from family court to criminal court. Vergari agreed to apply, and his office became one of four in the nation to win the grant. In 1978, he appointed Pirro to be the first chief of the new Domestic Violence and Child Abuse Bureau. Pirro was known to be an aggressive bureau chief. Due to possible coercion, she had a strict policy against dropping cases at a victim's request. Many people praised Pirro for her passion as Domestic Violence Bureau Chief, but she attracted increasing criticism from colleagues due her attention-grabbing behavior and violations of tradition. On multiple occasions, Chief District Attorney Vergari spoke to Pirro concerning her violation of office policy. She had issued press releases with her own name--and not Vergari's--on top. The relationship between Pirro and Vergari disintegrated in the late 1980s, after Pirro claimed sole responsibility for the establishment of the Domestic Violence and Child Abuse Bureau. On June 1, 1990, just five months prior to Pirro's first appearance on the ballot for County Court Judge, she attracted widespread attention and some criticism for rushing to conduct a bedside arraignment of Maria Amaya at the Intensive Care Unit of United Hospital in Port Chester. Amaya had been charged with four counts of second-degree murder for the deaths of her four children. She was a 36-year-old immigrant from El Salvador who had a history of being hospitalized for mental issues. Amaya had killed the four children and attempted suicide after believing that they were being corrupted by drugs and sex. Vergari had served as district attorney for Pirro's entire tenure as an assistant district attorney and her time on the bench. In 1999, he critiqued Pirro as "bright and capable" and someone who "plays hardball seeking publicity" but is also "very self-centered in everything she does". During a 1986 abortive campaign for lieutenant governor, Pirro claimed to have never lost a case in "about 50 trials". This number was disputed when presented in 2005 to colleagues, who said that the real number of trials personally handled by Pirro "wasn't more than 10". Pirro's then-spokesman, Anne Marie Corbalis, contended only that Pirro had a "100% felony conviction rate" as an Assistant District Attorney. In November 1993, Pirro was elected Westchester County District Attorney; she was the first woman to hold that position. She was re-elected in 1997 and 2001. On May 23, 2005, Pirro announced that she would not seek re-election to a fourth term as Westchester County District Attorney. On December 31, 1993--within hours of Pirro's midnight inauguration as District Attorney--Scripps newspaper heiress Anne Scripps Douglas was savagely bludgeoned in the head with a skull hammer by her estranged husband, Scott Douglas (who subsequently committed suicide by jumping off the Tappan Zee Bridge), as she slept in their Bronxville home. By the time police arrived, Scott Douglas had fled the scene, and Anne Scripps Douglas died in hospital on January 6. Pirro, already known as a passionate prosecutor of domestic violence cases, was a frequent presence in the media during the period between the murder and when Scott Douglas's body washed ashore in Riverdale in early March 1994. This increase in Pirro's national profile led to her surfacing as a frequent guest on network and cable television news in June 1994, when O.J. Simpson was arrested for the murder of his ex-wife, appearing frequently as a talking head for Nightline, Larry King Live, and Geraldo. Within months of taking office, Pirro undertook a costly renovation to the district attorney's facilities and expanded to an additional floor of the county courthouse. The largest expenses were a new kitchenette and a media room, costing $20,000, to assist Pirro's growing profile; additional expenditures also came to remodel her personal office with mahogany. Pirro was the first female president of the New York State District Attorneys Association. Also while district attorney, she was appointed by then Governor George Pataki to chair the New York State Commission on Domestic Violence Fatality Review Board. Its report and recommendations resulted in legislation passing that enhanced protections of, and safeguards for, the victims of domestic abuse. Pirro made her biggest procedural mistake as district attorney when she repeatedly refused to reopen the murder case of Jeffrey Deskovic. In 1990, Deskovic was falsely convicted of killing a 15-year-old girl and spent 16 years in prison before he was exonerated by DNA evidence. On May 26, 1986, Pirro, then an assistant district attorney, was announced as the running mate of Westchester County Executive and presumptive Republican gubernatorial nominee Andrew O'Rourke at a press conference in Manhattan's Roosevelt Hotel. Pirro was selected by O'Rourke and New York State Republican Committee Chairman Anthony J. Colavita after nearly a dozen individuals declined the position, including Erie County Executive Ed Rutkowski, Hempstead Presiding Supervisor Thomas Gulotta, and the Executives of Broome and Oneida Counties. Colavita, who said at the press conference that he "had so many say 'no' to me (during the lieutenant governor search), it doesn't hurt anymore", pointed to Pirro's prosecutorial experience, ability to effectively use crime as an issue, Italian married name, youth, and status as a woman when asked about her strengths as a candidate. Pirro's selection frustrated many New York Republicans, with Assembly Minority Leader Clarence D. Rappleyea Jr. traveling on May 27 from Albany to the first night of the State Republican Committee's Nominating Convention in Syracuse, to tell O'Rourke and Cloavita that his conference was concerned by Pirro's lack of political experience or statewide stature. Many Republicans also worried that if Pirro were nominated, their ticket would be too geographically dominated by downstate and the suburbs, with O'Rourke, like Pirro, being from Westchester, and the presumptive nominees for attorney general, Peter King and United States Senate, Alfonse D'Amato both hailing from Nassau County. On May 28, just one day prior to the scheduled vote for the lieutenant gubernatorial nomination at the state party convention in Syracuse, Pirro announced her withdrawal from the race, saying that her husband could not disclose his legal clients or the couple's business interests (later revealed to have been her husband's partial ownership of a Connecticut carting company with alleged mafia connections), and that many of his clients did business with the state, which would make it "virtually impossible" for her to serve as Lieutenant Governor. Pirro had privately informed O'Rourke and Cloavita of her decision during the evening of May 27, and the two were generally supportive, telling the press that her departure had nothing to do with Rappleyea's intervention. Pirro was replaced just six hours after her announcement by Michael Kavanagh, the District Attorney of Ulster County. CANNOTANSWER
