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 defense attorney.

Rivas Hernandez's cause of death has yet to be determined, with the county's medical examiner stating that her body was severely decomposed when it was found.

Many questions remain unanswered regarding the circumstances of her death and the singer's involvement, prompting intense speculation from the public and online communities.
