Cain was taken into custody in June by Chief Charlie Beck himself, after a separate investigation into a group of cadets suspected of stealing patrol vehicles led them to the discovery of the inappropriate relationship between the the 10-year veteran of the police force and the teenage girl. The D.A.’s office says that Cain, who is accused of assaulting the girl three times, “befriended” her.

After seven cadets were accused of stealing three patrol cars and crashing them, a “top-to-bottom” review of the cadet program led them to Cain. Subsequently, more than 100 weapons were found in Cain’s home, leading to the involvement of the Bureau of Alcohol, Tobacco, Firearms and Explosives.

Cain faces a possible maximum sentence of seven years and eight months in state prison if convicted.
