KOCHI: The police team probing the sexual assault case said if key accused Pulsar Suni had destroyed the memory card containing objectionable video of the actor or handed it over to someone, it would affect the investigation.
The video, if it exists, would be a crucial evidence in the case, and complement the victim’s statement regarding the alleged sexual assault.
Cyber experts say it will be very difficult to trace the video, reportedly stored in the external memory of a mobile phone, if the memory card has gone missing. “In Android phones, it can be verified whether the memory card is removed, or not, by checking the transaction log,” they say.
“It can also be checked where the video is saved - external memory or internal memory - using the same method. In the case of external memory, it can be checked whether the video was destroyed or not,” says cyber forensic expert Vinod Bhattathiripad.
Police sources said a detailed inquiry was underway, based on cyber evidence. Cyber experts are verifying call records of the friends of Suni, whom he contacted frequently. Suni did not use his mobile phone while on the run, and used the phones of others.
Despite questioning Suni and his accomplice Vijeesh several times, the investigators have not made any headway in tracing the mobile phone and memory card, even ten days after the incident. To make matters worse, Suni keeps changing his statement - first he told the police he had abandoned the phone at Ponnurunni, and on further questioning he said he threw the phone from the Goshree bridge.
It is learnt that no video/image was retrieved from the tablet and mobile phone recovered from Coimbatore.
