His personal life was marked by family instability, controversial friendships, ups and downs with the consumption of alcohol and drugs, accidents, financial and legal problems, especially the death under strange circumstances of Doris Adriana Niño.

His childhood was spent helping his parents and eight brothers with farm duties, while he was musically influenced by his locally renowned uncle, Martín Elías.

[9] Diomedes' intention of working at Radio Guatapurí was, once inside, to make friends with the announcers and Disc jockeys so that they could play the album that contained his song "La negra", which had recently been recorded by Luciano Poveda and Jorge Quiroz.

Diomedes continued exercising several trades, but always trying to interact with vallenato artists, even working as a prop, picking up wires and adjusting the sound of the microphones of "Los Hermanos López group".

[21] According to his friend Jaime Hinojosa Daza, Diomedes was going through financial difficulties and sold a bundle of lemons in the Valledupar market to buy a cassette and with a borrowed recorder he composed the song.

[22] The cassette was presented to the organizers of the contest, then he left to Carrizal because he did not have money to stay in Valledupar, so he heard the results of the competition through Radio Guatapurí, so he knew that they gave him third place.

[23] This same year, Juan Piña and accordion player Juancho Rois recorded the album "El fuete", in which they included Diomedes' song "La morriña".

Diomedes Díaz would achieve recognition in 1978 with the album "La locura", which he recorded with accordion player Juancho Rois, also native from the municipality of San Juan del Cesar.

[23] Diomedes would consolidate his regional success with accordion players such as Nicolás "Colacho" Mendoza, and then towards the interior of Colombia in the early 1980s, especially due to the deployment that his record label gave them, CBS which included commercials on the national chain.

[18] By this time, in Bogota had already consolidated Binomio de Oro, made up of his friend Rafael Orozco and the accordion player Israel Romero, so there started a competition in the market with them.

The album "Con mucho estilo" was recorded in 1981 with a song by Diomedes dedicated to his father Rafael María Díaz entitled "A mi papá" and another called "Bonita" inspired by his wife Patricia Acosta.

[30] This same year, Diomedes received an honorary degree from the 'Hugues Manuel Lacouture' school located in La Junta, nevertheless, he arrived late to the ceremony when there were no more attendees.

and "Yo soy Mundial", which was recorded in a tropical rhythm in honor of the Colombian football team during the qualifying rounds for the World Cup in the United States that year.

With great talent for singing verses and skilled in the accordion, in 1995 Iván Zuleta recorded with Diomedes the album "Un canto celestial" with which he paid tribute to the late Juancho Rois.

At this time Diomedes recorded the song "Ron pa' to' el mundo" with the salsa singer Joe Arroyo for the album Super Bailables del Año under the Sony Music label.

[37] In 1997 Diomedes interrupted his musical career due to the scandal that surrounded the death of Doris Adriana Niño, suffered Guillain-Barré disease and was a fugitive from justice.

[38] In 1999, being a fugitive from justice in the case of Doris Adriana Niño, his lawyers, headed by Evelio Daza, succeeded in getting court to temporarily exonerate Diomedes from the security measure, alleging that the singer suffered from Guillain-Barré syndrome.

[39] At the time, there were doing strong presence the paramilitary groups under the United Self-Defence Forces of Colombia (AUC), for which it was stated that Diomedes was under the protection of the organization outside the law, also his fans were silent and did not report their sightings of the artist in the region.

For his part, Germán Ortegón, Diomedes Díaz's artistic entrepreneur, explained that the alleged bag of cocaine was nothing more than a stamp of the Virgen del Carmen that someone from the public passed to him.

[46] On 22 February 2006, in Santa Marta, according to Johnny Bennedetti who hired Diomedes Díaz, the singer did not appear for a presentation, causing disturbances to the point of almost destroying the premises.

[48] The sudden separation between Diomedes and Zuleta occurred when Iván Zuleta decided to form a musical couple with the singer Iván Villazón, who separated from Saúl Lallemand, which generated the anger of Diomedes and the generation of several verses that caused "Piques" (Improvisation of vallenato verses) between both groups, but in the friendly sense of vallenato folklore.

Diomedes and Alvarito defeated the other nominees; Omar Geles and Alex Manga with the album "Prueba superada"; Jorge Oñate and Cristian Camilo Peña with "Te dedico mis triunfos"; Poncho Zuleta and Cocha Molina with "El nobel del amor"; and Binomio de Oro of Israel Romero with "Vuelve and pica ... el Pollo".

During this year went viral the video of the interview that the journalist Ernesto McCausland made with Diomedes in 1991 about death and the background related to the song of his authorship entitled "Mi ahijado".

He was generous to his followers and strangers, however, due to food demands for his numerous children, problems and legal breaches, he spent much of his fortune on drugs, alcohol, women and lawyers.

[12] His siblings were: Gloria María "Golla", Rafael Gregorio, Avelina del Carmen "Chama", Rosa Leonor "Ocha", Abel Antonio, Elizabeth "Icha", Elver Augusto, Juan Manuel and Elvira Luz.

[13] Diomedes was driving a truck that collided with a pile of sand in the middle of the road, in the place where the roundabout would be built with the monument "My piece of Accordion", north of Valledupar.

[65][66] Diomedes was treated by the cardiologist Rony López and the physiotherapists Carlina de Pantoja and Antonio Bolaño Mendoza, who applied physical and respiratory therapies, while the recovery process took place in Valledupar where the warm climate helped the treatment.

[75] During the trial, Díaz was tried as an "absent inmate"; the judge concluded that Niño had a great amount of drugs the night she died, but the Attorney General's Office determined that her death had been caused by provoked asphyxiation.

According to the trial, Díaz did not commit unintentional homicide (homicidio preterintencional), in which the aggressor wants to induce damage but ends up causing death, as the previous judge had ruled.

Sincerely, I think that no one is going to do something about it, because that process for escaping from prison is going to preclude ... Díaz had a suspended arrest warrant, had freedom benefits for supposedly being ill, but he wasn't detained.
