On the same day that Jacques Guillois was lauded at a Kiwanis Club dinner for his work as an East Hampton Town police detective over the past year, the suspect in his most prominent investigation, Jason Lee, a managing director of Goldman Sachs, was back in Criminal Court in Riverhead.
Mr. Lee, who was placed on leave by the financial giant after his Aug. 21 arrest, is accused of raping a 20-year-old Irish student on Aug. 20, his 37th birthday. By all accounts, there would have been no arrest without Mr. Guillois’s involvement.
The young woman, identified only by her initials, D.D., was reportedly traumatized by the alleged attack, said to have happened after an all-night liquor-and-drugs party at a Clover Leaf Lane, East Hampton, house rented for the summer by Mr. Lee and his wife, Alicia Lee. Ms. Lee, herself a financial adviser at Goldman, was at their Manhattan apartment at the time.
Detective Guillois reportedly treated D.D. “like she was his daughter” until the young woman felt able to go to headquarters and make a statement. After it was allegedly corroborated in part by others who had been at the house, Mr. Lee was charged with first-degree rape, which carries a minimum jail sentence of five years upon conviction.
That was only one of several arrests, as well as convictions, brought about by Mr. Guillois’s detective work, Chief Michael Sarlo said on Monday. “His interview skills and people skills, in both dealing with victims and dealing with suspects, are top notch. You can’t teach something like that.”
The chief cited several examples. One case began on a deserted Amagansett Main Street on the night of Oct. 23, 2012, when a local man, John Judge, was found by the side of the road, the victim of a hit-and-run driver. There were no witnesses and little physical evidence, save for a few pieces of the vehicle that had struck and killed Mr. Judge.
Using those pieces, gathered over the next seven hours by East Hampton Town detectives, the Suffolk County Crime Lab was able to identify the car as a 2004 Jeep Grand Cherokee. There were 1,374 matches in Suffolk County, 74 of them registered on the East End.
Mr. Guillois, now in his 10th year here after serving 16 years as a detective with the New York Police Department, methodically arranged to inspect each of the 74. He eventually tracked the Jeep being sought to a lot in New Jersey, where it was about to be auctioned off. Using paint chips recovered on Main Street, the detective connected the dots that led to a Montauk man, Edward L. Orr, 31.
After interviewing Mr. Orr, Mr. Guillois obtained a full confession. Mr. Orr, who was arrested on Feb. 7, 2013, pleaded guilty to leaving the scene of a fatal accident and is now serving two to six years in state prison.
Then there was the case of the Montauk man with an obsession with women’s underwear, who was burglarizing residents of downtown Montauk. Working with images taken from a surveillance camera, and having connected Franklin Guanga-Sinchi to an alleged rape that occurred in Montauk last summer, Detective Guillois was able to identify him as the suspect.
Mr. Guanga-Sinchi, who was indicted on four counts of felony burglary and released on $30,000 bail, has fled the area, possibly to Ecuador.
Mr. Guillois was also instrumental in the investigation that led to the arrest of Donald J. Torr, who police said secreted cameras throughout the Winterberry Lane house in Springs that he and his wife rented out to summer tenants. Mr. Torr viewed the resulting videos from his house in Florida, the police said, leading to 17 felony charges. He is due back in Riverhead Criminal Court tomorrow.
Detective Guillois “has outstanding intuition, and outstanding persistence,” Chief Sarlo said.
At the annual Kiwanis dinner in Southampton, which honors the top officer in each East End department, Detective Jeff Proctor of the Sag Harbor Police Department was also recognized, as was East Hampton Village Officer Steven Niggles. Detective Proctor, too, broke several prominent local cases, among them that of Daniel L. Gonzalez, 34, who was charged early last year with passing counterfeit $100 bills in the village.
The detective took charge of the investigation, which culminated in the department’s dramatic arrest of Mr. Gonzalez at La Guardia Airport, as he was about to board a plane to flee the area.
Detective Proctor’s work also led to the arrest of Devin K. Brevard, a Sag Harbor teenager who confessed to a string of burglaries there last summer.
Officer Niggles was recognized for his work in the coordinated “Stop D.W.I.” program run by the district attorney on the East End, which pools law-enforcement resources of the various jurisdictions in actions against drunken driving.
