DARIEN — Police arrested a Greenwich woman for allegedly driving drunk during a car accident on Middlesex Road back in August.

On Aug. 15 at 9:30 p.m., officers responded to a motor vehicle accident on Middlesex Road near Laurel Lane. A 20-year-old Darien man said he was driving his 2011 Chevrolet Malibu on Middlesex Road when another vehicle swerved into his lane. The 20-year-old swerved to avoid a head-on collision, but the other operator still struck the side and rear of his Chevy. The Malibu had heavy damage to its side and rear and the Darien man complained of minor neck pain from the accident.

Officers then approached the operator of the second vehicle, Milagros Rivera of Prospect Street in Greenwich. Rivera was still inside her car, looking for something while sitting in the front seat. Her vehicle, a 2005 Mercury Sable, had heavy damage to its front end.

Officers asked Rivera, 59, if she was injured. She told officers she was not sure. Officers then asked her how the accident occurred and, while speaking to Rivera, they detected the odor of alcohol. Rivera’s eyes were bloodshot and glassy and her speech was slurred. When asked by officers if she had been drinking, she replied, “I don’t know, maybe like one beer.”

The officers then asked Rivera to step out of the vehicle. She agreed but stumbled while exiting the car and required officers’ assistance to get out of the vehicle. Rivera then needed to lean on her car, because she was so unsteady on her feet, so officers helped her back into the driver’s seat. They asked her if she had any medical conditions and she told them she did not, but she was taking medication.

Officers were unsure if Rivera was drunk or injured from the accident, so they contacted Post 53. Upon arrival, Post 53 evaluated both drivers and determined it was best to transport both to Stamford Hospital.

On Sept. 1, Darien police secured and executed a search warrant for Rivera’s medical records at the time of accident. Darien police refused to state what her blood alcohol content was at the time of the accident, simply saying the state toxicology lab results came back showing Rivera’s BAC was over the legal limit.

Darien police applied for an arrest warrant, which they received on Sept. 30. Officers contacted Rivera on the morning of Oct. 1 and she turned herself in to police later that day. She was charged with driving under the influence and failure to drive right. Rivera posted a $250 cash bond and it scheduled to appear in Stamford Superior Court on Oct. 11.
