A tattoo on an accused’s arm, a silver coloured trolley suitcase spotted across multiple locations, and an extensive analysis of CCTV footage and digital records helped Chandigarh Police trace three alleged assailants in the Sector 11 chemist shop murder case to Jammu within 24 hours of the crime, police sources said.
The murder took place at Shri Kumar, a chemist shop in Sector 11, on June 13. Investigators identified the accused as Sunny Mehra, Aryan Sharma, and Amit Kumar and tracked their movements from Chandigarh to Delhi and then Jammu.
According to sources, one of the first breakthroughs came from CCTV footage captured after the murder. Investigators noticed a distinctive tattoo on Sunny Mehra’s arm, helping them identify him and narrow the investigation.
A silver coloured trolley suitcase carried by the accused emerged as another key clue. Police sources said the suitcase appeared repeatedly in CCTV footage collected from different locations and helped investigators track the group’s movements even when facial images were unclear.
“At several places, facial features were either unclear or the footage quality was insufficient for positive identification. However, the silver trolley suitcase was visible in multiple CCTV clips and helped establish that the same group was moving from one location to another,” a source said.
Police teams analyzed nearly 500 CCTV clips collected from Sector 11, Kajheri, ISBT Sector 43, Chandigarh railway station, Delhi railway station, Delhi ISBT, a hotel in Paharganj, and Jammu railway station. Of these, around 100 clips were from Chandigarh alone.
Sources said investigators spotted the suspects in at least 12 CCTV recordings while they were moving towards Kajheri shortly after the murder. The footage enabled police to reconstruct their escape route and establish a timeline of their movements.
Alongside CCTV analysis, technical surveillance teams examined mobile phone data. Investigators obtained tower dump data covering a radius of about 500 meters around the crime scene. When they compared it with tower dump data from Kajheri, hey found several common mobile numbers appearing in both datasets, strengthening suspicions that the accused had travelled there after fleeing the scene.
Police also analyzed the call detail records (CDRs) of Amit Kumar after learning about his criminal background. Investigators further examined Internet Protocol Detail Records (IPDRs), which helped them track internet activity, including applications accessed and data sessions generated through mobile devices.
Officials also analyzed Google account-linked data, including device activity, login records, and location-related information, and matched it with CCTV footage to map the suspects’ movements.
During the investigation, police found that the accused had allegedly been communicating through internet-based applications, including Telegram, Snapchat, and Zangi.
Sources said investigators also traced the accused to a hotel in Delhi’s Paharganj area, where they had connected to the property’s Wi-Fi network. CCTV footage from the hotel further confirmed their presence and movement.
Teams from the Operations Cell, Crime Branch and District Crime Cell worked simultaneously on different aspects of the investigation, including CCTV analysis, technical surveillance, and field verification.
By piecing together evidence from CCTV footage, tower dump data, CDRs, IPDR analysis, Google account records, and hotel Wi-Fi logs, Chandigarh Police were able to trace the accused to Jammu within a day of the murder, sources said.
