AIIMS Delhi's board handed its sealed report to the CBI investigating officer directly — the videography of the second post-mortem stays with the investigating agency separately, a procedural detail that suggests they're being careful about chain of custody here. Twisha was found hanging at her matrimonial home in Bhopal; she was the daughter-in-law of retired judge Giribala Singh. Her family's allegation that the first investigation and post-mortem had lapses is what forced the Madhya Pradesh High Court to order a second post-mortem in the first place. Giribala and her son Samarth appear before the court this Saturday as their judicial custody ends.
