California mom Sherri Papini was brutally kidnapped from her home, beaten and branded before being dumped on a highway nearly one year ago.

Papini, who has only now been able to describe her attackers to a forensic sketch artist, had said that her abductors were two women.

But investigators have collected male DNA from the clothing that she was wearing when she was found on Thanksgiving morning last year and female DNA that was discovered on Papini's body, the Shasta County sheriff's department has revealed.

The department also revealed that Papini's texts with a man in Detroit, Michigan have been investigated.

Officers traveled to the Michigan city on November 9 last year, back when she was still missing, the Redding Record Searchlight reported. She was allegedly kidnapped on November 2.

Police have not commented on the specifics of the Detroit investigation.

The news comes as sketches of her attackers were released.

'It has taken time for Sherri to recover to a point to be able to provide accurate details to the sketch artist,' the Shasta County Sheriff's Office said in news release. 'The sketches then needed to be finalized and approved for release by the FBI.'

She told police that her kidnappers, both Hispanic women, had taken care to cover their faces but she was still able to describe them in surprising detail.

The first woman was aged between 20 and 30 years old, about 5 feet 5 inches tall, with curly dark hair, thin eyebrows and pierced ears, she said. The second woman was between 40 and 50 years old, about 5 feet 7 inches tall, with long, straight black hair with some gray in it, thick eyebrows and pierced ears, the FBI said.

Anyone who recognizes either woman is urged to call the police.

Papini said the women were driving a dark-colored SUV with a 'large rear side window' when she was abducted.

'Sherri continues to look at photographs of various makes and models of SUV's in an effort to provide a more detailed description,' the sheriff's office said.

Papini disappeared while she was out jogging near her home in Redding, California, on November 2, 2016.

Her husband Keith made a number of frantic calls to the cops telling them he'd returned home but his wife wasn't there.

Papini's phone was discovered a mile away at the intersection of Sunrise Drive and Old Oregon Highway – neatly placed on the ground and with the headphones tidily wrapped around it.

Keith, who said at the time that his wife would never leave him or their children voluntarily, also launched an appeal – a GoFundMe account raising cash to pay for the search.

Managed by his sister Suzanne, who now lives in Long Beach, California, the Bring Sherri Home Safe appeal eventually raised a total of $49,070 – just short of the $50,000 goal. It is not clear what has happened to the money.

Papini was eventually found 150 miles away in the 452-person town of Yolo, which is approximately 15 miles north of Sacramento, early on the morning of November 24.

According to police, she was found on a rural road just off the I-5 freeway and, despite being chained, had managed to flag down a passing car.

Her long hair had been hacked off and Sheriff Bosenko said she had also been beaten and branded by her alleged captors.

'Sherri appeared battered and bruised, her hair had been cut to shoulder length and she had a brand on her right shoulder,' the sheriff's office said. 'Sherri, however, stated she had not been sexually assaulted, and there is no physical evidence to indicate otherwise.'

She was also branded with a threatening message.

'The Sheriff's Office continues to examine the brand and its possible meaning, but details of the brand remain confidential as part of the on-going investigation,' police said.

In a subsequent interview with police, Papini said she had been taken by two Hispanic women who went to great lengths to conceal their faces. Their car is understood to have been a dark SUV.
