Techie murder: Mobile phone may hold the key

Thousands of mobile phones that were active in the towers of various service providers covering the Nungambakkam railway station area have come under the scanner with investigators hoping to zero in on the suspect who killed Infosys employee S. Swathi on Friday.

While police are tight-lipped over Swathi’s call details or text messages, a special team of cyber crime experts are working on short-listing ‘suspicious’ mobile phones that were active hours ahead and after the murder. Even if the suspect had switched off his mobile phone at the time of committing the offence, it would still be possible to trace it had he turned it on in any of the neighbouring tower locations, police said on Wednesday.

Quoting an eyewitness, a senior police officer said the suspect neither had any conversation nor argument with the victim. However, the information that there was no conversation or argument did not mean that the suspect was a stranger to Swathi.

“Going by the CCTV footage, the suspect enters the premises at 6.31 a.m. and is seen walking out at 6.42 a.m. He spent just 11 minutes, which includes the time he took to walk to and from the crime scene to the surveillance camera location. Maybe, he spent barely two or three minutes waiting for the victim and attacking her...,” the officer said.
