Spanish dentist, Mario-César Deus Yela, who is accused of murdering his twin sons in 2017, has committed suicide while in prison.

Yela, a dentist who lives in Spain, was in South Africa in 2017 to see his three young children - the twins, Maximo and Octavia, and a seven-year-old son.

Yela and the children’s mother, Julia Engelhorn, were divorced in 2015 and the couple had previously lived in Spain.

She relocated to South Africa in 2012.

Police was called to Yela’s holiday apartment at Prince Road, Hout Bay after Engelhorn found their lifeless bodies.

Her attorney, Juan Smuts, said Yela dropped the older son at school that morning. The twins were with him.

As far as he knew, the parents had not argued.

Cops have yet to reveal how the twins were killed, but it is believed they were stabbed.

Yela had allegedly fled the scene in Engelhorn's car. Police tracked down her car to Wynberg, where Yela was arrested.

Pollsmoor Prison spokesperson Lewis Davids confirmed Yela’s death but says he cannot give a further comment until Simphiwe Xako, Head: Communications and Marketing, Department of Correctional Services, Western Cape Region gives an official statement.
