LINCOLN — A Central Falls councilwoman whom the police say was driving erratically on Great Road Friday night with a 10-year-old boy asleep in the back seat, has been charged with driving under the influence of alcohol, driving on a suspended license and with refusing to submit to a chemical test.

Eunice DeJesus DeLaHoz, 43, was driving a gray Pontiac sedan shortly after 11 p.m. Friday when a Lincoln patrolman working a stationary traffic post observed her turn from Front Street onto Great Road.

The sedan was traveling south straddling the double yellow line and at one point swerved back into the southbound lane to avoid striking a vehicle headed in the opposite direction, according to a report written by Patrolman Ryan J. Laboissonniere. At that point, the sedan came within inches of striking the curbing in the southbound lane, according to the report.

Laboissonniere activated his emergency lights to stop the vehicle at Great Road and Smithfield Avenue.

“As soon as the suspect vehicle pulled to the side of the road, the driver’s door opened immediately and I observed the operator’s left hand holding what appeared to be a gold badge,” Laboissonniere wrote.

The patrolman said he got out of his cruiser and ordered the driver to close the door and open the driver’s side window, which he said she refused to do. As he approached the vehicle, he noticed a boy sleeping in the back seat.

“I smelled a strong odor of alcohol emanating from her person and observed the operator to have watery, blood-shot eyes,” he wrote in his report.

As the officer tried to get DeLaHoz to open the window and close the door, she “held up a badge,” he wrote. After asking her a third time, the patrolman said he opened the window himself and “then closed the door for my safety.”

When he asked DeLaHoz for her license, registration and insurance information, DeLaHoz stated, “I’m on the City Council in Central Falls.”

DeLaHoz told Laboissonniere she was coming from a reunion, he wrote, and she said she had consumed “three glasses of wine.”

According to the report, DeLaHoz failed field-sobriety tests — including failing to follow the tip of the patrolman’s pen with her eyes without moving her head; touching her nose when she was instructed to touch the tip of the pen; and losing balance on three occasions.

DeLaHoz said she had an injury that prevents her from walking in a heel-to-toe fashion, but she did not need to tell him the nature of the injury because of the Americans with Disabilities Act.

When Laboissonniere asked her to attempt the test, he wrote that she replied, “I’m on the City Council in Central Falls and I know my rights. I do not have to do anything.”

At that point, she was arrested and taken to headquarters.

DeLaHoz is scheduled to be arraigned July 10 and to appear in Rhode Island Traffic Tribunal July 13.

No one answered the phone at DeLaHoz’s home on Wednesday.

The car is registered to Julio Castillo, whom the councilwoman called twice from the police station.

Police Capt. Raymond Bousquet said Wednesday that he does not know the connection between DeLaHoz and Castillo. Bousquet refused to identify the 10-year-old in the car. Bousquet said the child was released to a caregiver.

The police contacted the state Department of Children, Youth and Families Tuesday. A DCYF spokeswoman confirmed the agency was contacted but declined to answer any other questions.

DeLaHoz was elected to the Central Falls City Council in a special election in February 2007 and relected in an uncontested race in November of the same year.

She was unable to provide a driver’s license to the police Friday night. She told the patrolman she left it in a store at the mall last week, and although she should have received it in the mail from the store by now, she had not.

A license check indicated DeLaHoz has a suspended license for failing to appear in court Nov. 14, Laboissonniere wrote.

She told the patrolman her license was not suspended and that the registry had given her “a paper to carry around if I get pulled over.”

She said that paperwork was in her other car, according to the police report.
