The day after a body was found in his car in Hollywood, singer D4vd was belting his TikTok hit Romantic Homicide - a brooding breakup song about killing an ex with no regret - to a sold-out crowd in Minneapolis.

The US recording artist had self-launched his music career from his sister's closet while working a part-time gig at Starbucks. It led him to viral fame, millions of followers online, and a global tour. But all of it came to an abrupt halt last month with the discovery of a severely decomposed body in the front trunk of his Tesla.

The corpse was identified as that of 15-year-old runaway Celeste Rivas Hernandez.

A month later, mystery still surrounds the teen's death, as well as her relationship to the 20-year-old singer, whose legal name is David Anthony Burke.

Deep dives into his macabre oeuvre - which is peppered with references to death, remembrance, violence and bloody motifs - have led some to question if life was imitating art and vice versa.

The young singer has yet to publicly comment on the case or the grim discovery in his car. His spokesperson has only said that he is fully cooperating with authorities and he has since hired a prominent criminal defence attorney.

Rivas Hernandez's cause of death has yet to be determined; the county medical examiner has stated that her body was severely decomposed at the time of discovery, delaying any final ruling on her death.

When the teen's remains were found in D4vd's Tesla on 8 September, she was wearing a tube top and leggings, and featured a tattoo nearly identical to the singer's own. Days after the grim discovery, D4vd's world tour was canceled, and endorsements were dropped.

As authorities continue to investigate, questions linger surrounding the nature of D4vd's connection with Rivas Hernandez. The young singer's silence on this matter has added to the intrigue among fans and observers.
