Newly released court documents reveal new details about a Tucson police officer suspected of committing sexual misconduct with a woman he was investigating, including how a DNA match helped lead to his arrest.

Court documents and police say Officer Richard Daniel responded Jan. 13 to a call about a confrontation between a clerk and a woman inside a 7-Eleven convenience store at 4295 E. 29th St.

Daniel found the woman as she was walking home and learned she had an outstanding arrest warrant, records say.

The woman asked Daniel not to call the warrant in as she would be sent to jail, according to records.

Police said Daniel asked her to perform oral sex on him and then sexual intercourse after she refused the first suggestion. Police then say the woman lied that she was pregnant to avoid having sex with him.

The report says Daniel offered to take the woman to another location, but the woman told him that wouldn't work. The woman then agreed to take Daniel to an apartment to give him oral sex, but said she had to ask her husband for permission, police say, as the two used to be swingers.

Documents say the husband told investigators the woman entered the apartment with Daniel, whom he remembered from a prior service call at their apartment. The man said Daniel told him about the confrontation at the convenience store and that he wasn't taking the woman to jail, documents say.

Arrest documents say the woman told her husband that Daniel wanted her to perform oral sex on him in and in exchange her outstanding warrant would be "squashed."

The man told investigators he couldn't believe what he was hearing and that Daniel shrugged his shoulders when asked if he was being serious. Documents say the man left for the 7-Eleven to learn more about the confrontation.

Court documents say the woman was scared and offered to perform another sex act instead, but the officer insisted on oral sex, which she did. Daniels used a tissue to clean up.

The report then says Daniel told the woman to take care of the arrest warrant and left the apartment.

Court documents and police did not specify how officers learned about the incident and began investigating.

Documents say investigators swabbed part of the floor where the encounter occurred, noting no substance was visible. The investigators tried interviewing Daniel at his home, but he refused to answer any questions without an attorney.

The investigators got search warrants to obtain swab samples from the officer for DNA testing and search his locker, where they found condoms and crumpled tissues containing "an unknown substance," documents say.

Forensic analysis found the substance matched Daniel's DNA on Jan. 19, court documents say. Daniel was called to the police station the next day where he was placed under arrest.

Daniel was booked into the Pima County Jail on charges of unlawful sexual conduct as a peace officer and tampering with physical evidence. A spokesman with the Pima County Sherrif's Department said Daniel has since been released pending his next court hearing.

Neither police or court records specified what the warrant against the woman involved.
