Sherri Papini cannot describe her abductors because her face was covered during her 22-day disappearance, Shasta County Sheriff Tom Bosenko told KRCR-TV on Wednesday, December 14.

According to the local news outlet, authorities “have no new information to release” about the case as evidence is still being processed by the Department of Justice more than six weeks after the mother of two’s November 2 disappearance.

Sheriff Bosenko told KRCR-TV that there have been no sketches of the suspects, who Papini described as two Hispanic women, because sketches “require a lot of detailed information.” The site reported that Papini’s head was “covered most of the time,” and when it wasn’t, her captors’ faces were concealed. The sheriff also noted that trauma victims often have difficulty remembering specific details.

Despite the lack of information, Sherri and her husband, Keith, who share 4-year-old son Tyler and 2-year-old daughter Violet, have continued to cooperate with investigators, according to KRCR-TV. Sheriff Bosenko told the outlet that authorities “are in almost daily contact” with the couple and want the case, which he described as a “top priority,” to be solved “as soon as possible.”

As previously reported, Keith reported his wife missing on November 2 after she disappeared during a jog near their home in Redding, California. Three weeks later, on Thanksgiving Day, Sherri was freed by her abductors on the side of a road in Yolo County. She was physically abused during her three-week captivity and was discovered chained, branded and with her blonde hair cut off.

Police are searching for two armed Hispanic women driving a dark-colored SUV.
