The mother of a missing 7-year-old Brooklyn boy was released from jail Tuesday, Feb. 2 after passing a polygraph test that revealed she has no knowledge of her son's whereabouts, according to media reports.

Jennifer Rodriguez, 23, is the biological mother of Patrick Arnold, but the boy was living in foster care when he went missing on Jan. 22.

Rodriguez was jailed for a week due to contempt of court charges and the judge threatened to have her put back in jail if she doesn't cooperate fully with investigators and her son isn't found soon, reports WABC-TV.
