Chandigarh, Aug. 2 -- During the resumed hearing of the Sippy Sidhu murder trial on Friday, the CBI court was informed that a key forensic witness, Dr SS Baisoya, senior scientific officer at the Central Forensic Science Laboratory (CFSL), Chandigarh, has died. Special CBI judge Alka Malik said that the summons sent to Dr Baisoya had been returned with a report of his death. In response, the public prosecutor formally gave up on presenting the witness and recorded a separate statement to that effect. "Summons sent to Dr Baisoya, senior scientific officer, CFSL Chandigarh, received back with the report of his death. Learned public prosecutor has given up, by making a separate statement," observed the judge. Following this, the court issued fresh summons to two additional witnesses, Dr Amandeep Singh and Dr RM Tripathi, to appear on the next hearing date- scheduled forAugust 8. The case pertains to the cold-blooded murder of national-level shooter and advocate Sukhmanpreet Singh Sidhu, popularly known as Sippy Sidhu, who was shot dead in a park in Chandigarh's Sector 27 on September 20, 2015. Kalyani Singh, daughter of a retired Punjab and Haryana high court judge, is facing trial for the murder. When CBI took over the case in 2016, it found that Kalyani was in a close relationship with Sippy, but he refused to marry her. Also, Sippy leaked/shared her objectionable photographs to her friends and family, who then met Sippy and pleaded with him to delete all such pictures. The victim's family has consistently maintained that Kalyani's motive was revenge, citing the rejected proposal and damaged reputation. According to the CBI chargesheet, Kalyani driven by the obsession of failed love affair (rejection of marriage proposal), fuelled by feeling of anger and morbid jealousy (due to affair of Sippy with another girl) and humiliation/embarrassment to the family (due to leakage of her objectionable photographs) hatched a conspiracy and called Sippy to the Sector 27 park and killed him by using a .12-bore gun. Sippy's late grandfather, SS Sidhu, was a former Punjab and Haryana high court judge and late father, IPS Sidhu, was the additional advocate general of Punjab. His mother, Deepinder Sidhu, 69, a homemaker and brother Jasmanpreet Singh Sidhu, 39, an advocate and legal adviser for SGPC, live in Phase 3B2, Mohali....
