Sheriff's officials in Yuma County are asking for felony charges against a female inmate who allegedly had sex with three sheriff's detention officers.

The detention officers were arrested last month and have been charged with felonies for alleged incidents with four inmates over several months. They are no longer employed by the sheriff's office.

Deputies brought inmate Shannon Rose, 32, to Yuma Justice Court on Tuesday, where she made an initial appearance on seven felony charges of unlawful sex acts by a prisoner. The Yuma County Attorney is expected to decide by Friday if she should be formally charged.

Sheriff's Capt. Eben Bratcher said three other female inmates are involved. He said the investigation was ongoing and a decision on possible charges has not yet been made.

"There is still more for us to find out," Bratcher said.

According to court records, Rose admitted to having oral sex with at least three detention officers during her nine months at the Yuma County jail.

Court records said Rose admitted to passing sexually explicit notes to the detention officers, which eventually led to having conversations with them.

Rose was serving a 315-day sentence when the alleged crimes with the detention officers happened. She was scheduled to be released in less than three weeks.

Rose admitted to at least 12 sexual acts with detention officers, court records indicated.

Former officer Justin Herrera, 26, has been charged with two counts of unlawful sexual conduct by a corrections officer.

Jose Espinoza, 26, has been charged with six counts of unlawful sexual conduct by a corrections officer, sexual assault and kidnapping. Kenneth Smith, 34, was charged with one count of sexual assault and three counts of unlawful sexual conduct by a corrections officer.
