A 52-year-old man from Bohemia was driving under the influence of methamphetamine in East Hampton, according to East Hampton Town police, who said they found five small Ziploc bags, three glass pipes, and one plastic tube, all containing a white residue, in a backpack on the passenger floor of his car. The residue later tested positive for methamphetamine. Gennaro A. Viteritti had been speeding — going 50 miles per hour in a 30 m.p.h. zone according to police — when they pulled over his 2007 Chrysler, which had been headed south on Springy Banks Road near Treescape Drive on May 29 at about 1:30 a.m. Police asked him to get out of the vehicle and said that he could not stand and collapsed to the ground. He was unable to perform field sobriety tests.The officer included a list of odd behaviors in his report, which said that Mr. Viteritti’s movements were animated, his pupils were dilated, his eyes were darting, his jaw was clenched, his speech slurred, he had trouble focusing, he was sweating profusely, and he even had a hard time holding up his head. Because of a conviction within the last 10 years, Mr. Viteritti was charged with felony driving while ability impaired by drugs as well as three counts of seventh-degree criminal possession of a controlled substance, a misdemeanor. A check of his license revealed that he was supposed to be driving with an Interlock device to test for alcohol before the ignition would start. He was charged with an additional misdemeanor since the device was not there. He was held for morning arraignment. Justice Steven Tekulsky set bail at $2,500 cash or a $5,000 bond. He was turned over to the Suffolk County sheriff’s office and held until Friday, when he was released. Luis A. Parra-Gomez of Springs was arrested on a felony drunken driving charge on Saturday. Police said he was headed north on Three Mile Harbor-Hog Creek Road, near Copeces Lane, in a 2008 Honda when he failed to dim his high beams for oncoming traffic. When police stopped the 32-year-old at about 1:15 a.m., they said he appeared intoxicated and performed poorly on field sobriety tests. Police then found that he had been convicted on Jan. 19, 2017, of driving while intoxicated, which raised the charge against him on Saturday night to a felony. His license had also been suspended for failure to pay a driver responsibility assessment in April 2017 in connection with the D.W.I. conviction, and his driving privileges had not yet been restored. He was therefore charged with an additional felony. Justice Tekulsky released him on $5,000 cash bail. Mr. Parra-Gomez “denies the allegations and contests the validity of the stop,” according to his attorney, Carl Irace.A 33-year-old East Hampton man was driving drunk with a significant amount of cocaine in his car, according to police, who stopped his 2016 Nissan on Three Mile Harbor Road near Oakview Highway on May 27, at about 7:20 a.m. Police said Klever Fabian Barrera-Hoyos had been doing 65 in a 40 m.p.h. zone, failed to keep right, and crossed over a solid yellow line. He also appeared intoxicated, they said. Following field sobriety tests, police found he had a blue plastic Ziploc bag with cocaine that weighed 500 milligrams or more — an amount that led to a felony charge of fifth-degree criminal possession of a controlled substance, as well as driving while intoxicated, a misdemeanor. Justice Tekulsky released him on $1,000 bail. Police also arrested Matthew I. Silich, 22, of East Hampton in the early morning hours of May 28. Police said he was swerving in a 2010 Volkswagen on Main Street, near Newtown Lane, in East Hampton at about 4:15 a.m. He had crossed over the double yellow line several times before police pulled him over, the officer said. Mr. Silich appeared intoxicated, performed poorly on field sobriety tests, and was charged with misdemeanor aggravated D.W.I. for allegedly having a blood alcohol level above .18. Later that morning, Justice Tekulsky released him on his own recognizance. William M. Edwards, 29, of Plainview was also charged with drunken driving. Police found him in the driver’s seat with his 2010 Honda Accord running but stopped at the intersection of Montauk Highway and Westgate Road in Wainscott on May 28 at about 1:45 a.m. During a search, an officer said he found a small amount of marijuana in a small plastic bag. He was charged with unlawful possession of marijuana, a violation, in addition to misdemeanor D.W.I. He was released on $200 cash bail later that day.
