A heartbroken mother is still searching for answers nearly four years after her son was found dead in the California desert with his organs missing. 

Ryan Singleton, a 24-year-old aspiring writer and filmmaker, vanished in July 2013 after flying from Atlanta, Georgia to Los Angeles.

He rented a car for a trip to Las Vegas, but as he drove through the Mojave Desert on July 9, 2013, his car broke down near Baker.

Singleton was picked up by a Highway Patrol Officer and driven to a rest stop in Baker.

Once there, he called a friend who lived three hours away and asked for help, his family said. 

But when the friend arrived, there was no sign of Singleton and a missing person's report was filed.

It was two months before joggers came across Singleton's decomposing body, which was missing its organs, in an area that had been extensively searched by detectives and investigators.

His mother, Iris Flowers, said at the time that investigators called her and said: 'Ma'am, there were no eyes, there was no heart, there were no lungs, there was no liver, there were no kidneys.'

The San Bernardino County Coroner's Office said there was no official cause of death after the body was found, but that 'the body was severely decomposed. Animals might have been involved.'

Flowers said she wants to know what happened to her son, who had recently married and separated from his husband, Kythe Brewster.  

'The truth. The answers. The justice. The accountability of what happened to my child really,' she told WXIA.

Flowers explained that her son left her home in Georgia to move to New York to chase his dreams of becoming a male model in 2010, but later ended up in Los Angeles to pursue film production. 

'I'm glad that he did go. He took the courage and he went. He was brave. Ryan was never afraid to try anything. He was never afraid. Most things he tried, he mastered,' Flowers said.

But in December 2012, he left Los Angeles to move back to New York where he married Brewster, who at the time worked as a celebrity stylist. 

Singleton left New York a few months later and returned back to his mother's home in Atlanta to separate himself from Brewster.  

The last time his mother saw him alive before he left for California in July 2013, she said he was worried something bad was going to happen.

'Something bad is going to happen to me isn't it?' he asked his mother, she told WXIA.

Flowers asked him what he was talking about and asked if he owed someone money, to which he said no.  

'I've done a lot of things to hurt a lot of people,' he told his mother she said.

Flowers said that she never understood what exactly her son was talking about.

'I don't know if he felt some kind of way because he left the (production) team, married Kythe and it didn't work out with Kythe and now he's home. He knew he hurt me by disappearing and not communicating with me. Anybody outside of that, I couldn't figure out who it could be,' Flowers said. 

His mother said she's unable to afford an attorney and her son's case is still an open death investigation in the state of California. 

She said that she thinks her son was killed for his organs.
