( CNN ) -- Texas child welfare officials have asked a judge to order a teenage member of a polygamous sect to let them take DNA from her infant so they can determine the father 's identity , according to court documents filed in the case . An aerial view taken last year shows some living quarters at polygamist leader Warren Jeffs ' Texas ranch . The teenager , who is younger than 18 , is a member of the Fundamentalist Church of Jesus Christ of Latter-day Saints . She is believed to have had the baby in June , Texas Department of Family and Protective Services attorneys said in the documents , filed earlier this month . Child welfare authorities also believe the teenager was married at 14 to an adult male , department attorney John Dolezal writes in the motion . `` In order to determine the identity of the sexual perpetrator who engaged in sexual intercourse with [ the girl ] while she was a minor , which act consequently led to this pregnancy , the department is required to perform genetic testing on the child so as to determine who that individual is , '' the motion said . CNN is not naming the teenager , as authorities allege she is a victim of sexual abuse . A hearing on the matter was conducted Tuesday . Patrick Crimmins , spokesman for DFPS , said the teenager showed up without the baby . An agreement was reached by both sides during the hearing , Crimmins said , but the judge ordered that the agreement not be made public . The department has attempted to resolve the issue with the teenager but had not been successful , the motion said . The FLDS was thrust into the spotlight in April , when child welfare workers removed more than 400 children from the sect 's Yearning for Zion Ranch in Eldorado , Texas , citing allegations of physical and sexual abuse . Following a court battle , the Texas Supreme Court ordered the children returned , saying there was no evidence they faced imminent danger of abuse on the ranch . Critics of the FLDS say the sect forces girls into marriage with men . To date , 12 FLDS members have been indicted on charges including sexual assault of a minor , conducting unlawful marriages involving a minor and bigamy as part of an ongoing investigation , according to Texas Attorney General Greg Abbott 's office . They include Warren Jeffs , the FLDS leader and `` prophet . '' Jeffs was already facing charges of sexual assault of a child in Texas , which carries a sentence of up to life upon conviction , when he was indicted earlier this month on a first-degree felony count of aggravated sexual assault . He is also facing a sentence of up to life in Utah , where he was convicted on accomplice to rape charges for his role in the marriage of a sect member to a 14-year-old . He is awaiting trial in Arizona , where he faces similar charges . The FLDS is a 10,000-member offshoot of the mainstream Mormon church . It openly practices polygamy on the ranch , as well as in two towns straddling the Utah-Arizona border .
