A Manhattan judge declared a mistrial Tuesday on a single count of resisting arrest against the wife of a former police officer after the jury said it was deadlocked on the charge.

Afterward, several jurors said that their vote was 11 to 1 in favor of acquitting the woman, Wilma Doré-Almonor, and that the case might have highlighted problems with the Police Department’s stop-and-frisk policy.

Ms. Doré-Almonor was in an altercation with police officers at the 30th Precinct station house last year after she went to collect her son, 13 at the time, whom the police had stopped on the street and detained.

The son, Devin, was released without charge, but only after a fracas that led to the arrest of Ms. Doré-Almonor and her husband, Merault Almonor, who had spent 12 years as a police officer.
