Prosecutors have convened an investigative grand jury in the case involving singer D4vd after the body of a teenage girl was discovered in the trunk of his vehicle, according to court proceedings.

The decision to empanel the grand jury came after investigators encountered difficulties with uncooperative witnesses during the investigation, sources familiar with the matter indicated. Grand juries are typically used when prosecutors need additional tools to compel testimony or gather evidence in complex cases.

The discovery of the teenage victim's body in D4vd's car marked the beginning of what has become an extended investigation. The circumstances surrounding the death and the timeline of events leading to the discovery have not been publicly disclosed by authorities.

D4vd, whose legal name has not been released, gained prominence in the music industry in recent years. The singer's representatives have not responded to requests for comment regarding the investigation.

Investigative grand juries have broader powers than regular grand juries, including the ability to issue subpoenas for documents and testimony. The proceedings are conducted in secret, and it remains unclear how long the investigation may continue or what charges, if any, may result from the inquiry.
