Singer-songwriter Jerry Demara, who appeared on Mexico's version of The Voice, died in agony on Monday after improperly injecting vitamins into his buttocks. He was 42 years old.

The Mexican performer, born Gerardo Demara, passed away at a hospital in Brawley, California.

Demara rose to fame after appearing on The Voice Mexico in 2012  

She mentioned that he had undergone surgery but continued suffering from complications. Plascencia repeatedly asked friends and fans to pray for his recovery, and appealed to God for a 'miracle.'

On Saturday, a visibly unwell Demara shared a video on his Facebook page from the hospital, explaining that he was there 'because I have a problem in buttocks.'

The married dad-of-two went on to say that he had mistakenly injected himself with vitamins on three different days.

'I put the last injection the day before yesterday but on the same side,' he explained. 

Demara did not specify the type of vitamins he had used. 

Vitamin injections have been popular among some celebrities seeking to increase their energy levels. 

Demara's 2018 record was nominated for a Latin Grammy in the Best Regional Album category 

As a composer, Demara had written songs for various Mexican recording artists and bands 

'I am in incredible pain. I have had it for six hours. You can see how I am,' he said in Spanish while wincing and grimacing. 

Demara criticized the quality of care at the hospital, claiming that staff have been ignoring him and failing to do more to help him.  

'I truly have a sense of helplessness,' he lamented. 

Born in Baja California, Mexico, Demara rose to fame in 2012 when he appeared on The Voice Mexico, known as La Voz. 

In 2018, his six-track record Brindemos earned a Latin Grammy nomination in the Best Regional Album category, reported Billboard.com.  

Demara's widow, Claudia Plascencia, announced his passing on Facebook and mourned his untimely death. Earlier, she had asked for prayers from friends and fans
