A Jefferson Parish Sheriff's deputy has been arrested for allegedly raping a minor three years ago, and the victim's family is wondering how he got through the Sheriff's Office's screening process. Jonathan Andrew Este', 25, of 821 Heritage Avenue in Terrytown, was booked Monday with forcible rape and three counts of felony carnal knowledge of a juvenile after a 16-year old West Jefferson girl told a deputy that he raped her three years ago. Este', who has been with the Sheriff's Office for slightly more than a year, remains at the Jefferson Parish Correctional Center on $82,500 bond. Sheriff Newell Normand said that while a deputy was investigating a family disturbance Friday, the victim reported that she had been raped in November 2005 by Este'. The victim said she met Este' in an Internet chat room, and they dated for a month. Normand said Este' took the girl to a Gretna apartment, where she said he raped her. The victim maintained a relationship with Este', who was 22 years old at the time, for about eight months, and they had intercourse on four occasions. The other three incidents were consensual, Normand said. The girl said Este' impregnated her, but she later had a miscarriage. When Este' was confronted by investigators, he admitted to having sex with the victim on four occasions, but said each encounter was consensual. However, he acknowledged that he knew the victim was underage when he had sex with her. Este' has been fired, and all of the incidents took place before he got hired, Normand said. "Any time that we arrest one of our own, it's one of the saddest days as it relates to our organization," Normand said at a Tuesday afternoon press conference. "Having said that, we are all individuals that are fallible... Adults don't have sex with juveniles." However, the victim and her family are wondering how Este' was able to initially get hired by the Sheriff's Office, particularly since prospective hires are required to take a polygraph exam. The victim and her family said the Sheriff's Office has told them not to discuss the incident, but they said the rape has been a tragic event for their family. The Times Picayune does not identify the victim in sexual abuse complaints and is not identifying her parents. The victim said that she has had serious emotional problems since the rape, especially since she got pregnant. The girl's family found out about the incident only last week, when she was taken to River Oaks Psychiatric Hospital and she admitted what happened. Until then, they did not know that she had been pregnant. The victim said she feels betrayed that the Sheriff's Office would hire someone like Este'. "He's a police officer. How did he slip through the cracks?" she said. "He made me afraid to tell anyone." Neighbors of Este' said there was no indication that he would do anything like rape a minor. Este' had been living in a home in the quiet community for about three months, with a roommate who also is a Jefferson Parish sheriff's deputy. All of his neighbors said he and his roommate seemed like quiet young men. Col. John Fortunato, a spokesman for the Sheriff's Office, said Este' may have been able to pass his pre-employment polygraph because in his mind he may believe he did not commit a crime. The Sheriff's Office only asks prospective deputies if they have committed an undetected crime, so if an individual does not believe their actions were criminal, it would not cause a spike during the test, Fortunato said.
