Two Brooklyn siblings who had spent Sunday night in Montauk with a group of friends spent Monday morning in East Hampton Town Justice Court, where they were arraigned on charges of driving while intoxicated. East Hampton Town police pulled over Harryson F. Gallegos, 25, at about 3:30 a.m. as he was headed west on Napeague, saying his 2003 Nissan S.U.V. had been speeding. His sister, Ashley M. Gallegos, 21, was in the car, along with a number of other passengers. Mr. Gallegos, who according to the report told police that “I’m just trying to get all my friends home because they’re drunk,” allegedly failed roadside sobriety tests as well as a breath test back at Wainscott headquarters, recorded at .13 of 1 percent alcohol in his blood. Just over an hour later, an East Hampton Village officer stopped the same S.U.V. on Pantigo Road near CVS, this time with Ms. Gallegos behind the wheel. Police said she had failed to signal a turn, and that the overcrowded vehicle obstructed her view of the road. “The driver stated she had no driver’s license and had been drinking,” the officer wrote. She was said to have failed the same roadside sobriety tests as her brother had an hour earlier. At village police headquarters on Cedar Street, she reportedly had a blood-alcohol reading of .14. “The other 10 occupants of the vehicle were instructed to call taxis to go home,” the report says. They included the owner of the Nissan. “Due to his high level of intoxication,” the officer wrote, he took the man’s car keys away and told him to “retrieve them later in the day.” While the siblings had started out with 10 friends, they ended up with 1, when they were reunited at their arraignment. Justice Lisa Rana set bail for each at $350, which the friend posted for Mr. Gallegos, who then bailed out his sister. The two are due back in court today. Village police charged Kevin G. Robertson of East Hampton late Friday night with drunken driving. Police said his blood-alcohol level was .13. During his arraignment Saturday morning, Justice Rana asked him if his wife knew he had been arrested. Mr. Robertson shook his head. “You’re going to have to tell her sometime,” Justice Rana said, before releasing him, in light of his ties to the community, without bail. Town police arrested Michael E. Politan, 30, of Tannersville, N.Y., in the early morning hours of June 11. Police said his blood-alcohol level was recorded at .14. Mr. Politan had no prior convictions, Justice Rana said during his arraignment later that morning, but did have a previous arrest on a D.W.I. charge, which is pending. He was released on $500 bail. Allison Brown, 28, of Delray Beach, Fla., was arrested by town police early last Thursday. She told the court that morning that she had come here to work for the season and was staying in Montauk. After she was arrested, she refused to submit to the breath test at headquarters, and Maggie Bopp, an assistant district attorney, told Justice Rana that “there are numerous out-of-state charges that are alcohol-related.” She asked that bail be set at $1,000. Upon hearing the amount requested, Ms. Brown began sobbing. “Does anybody know you’ve been arrested?” Justice Rana asked. “I called my friend,” said Ms. Brown. “I spent all my money to get here.” Justice Rana paused for a moment. “Ma’am. My question is, can you make bail?” “Not that much,” the defendant answered, still crying. “Bail is going to be set at $300,” Justice Rana said. The bail was posted later that morning, and Ms. Brown was released, with a future date in court.
