LUCKNOW, April 7 -- A month-long Google search trail on cyanide, poisons and methods of administration recovered from the prime accused's mobile phone became the key breakthrough in cracking what was initially suspected to be a spurious liquor tragedy but later emerged as a premeditated triple murder in Meerut's Daurala, senior superintendent of police Avinash Pandey said on Sunday. Pandey said examination of the accused Pawan Ahlawat's mobile phone revealed sustained online searches over several weeks relating to cyanide, its procurement, fatality levels and possible methods of administration, providing critical evidence of planning and conspiracy. Police arrested all three accused - Pawan Ahlawat, Ashok Verma and Alka - on Sunday and booked them on charges of murder by use of poison and criminal conspiracy. Further forensic examination of the mobile phone, search logs, chemical traces and call detail records is underway. While Pawan and Ashok are in their late forties, Alka is in her late thirties. "The search history clearly showed sustained online research about cyanide, its procurement and use. This became a crucial breakthrough in the case," a police officer associated with the probe said. According to the SSP, the digital footprint helped investigators establish that the deaths of Ankit alias Daulat (32) and his two associates, Baburam (60) and Jitendra (45), were not caused by accidental toxic liquor consumption but were the result of a carefully executed murder plot. The three men died on the night of April 3 after consuming country-made liquor in Daurala. The deaths had initially triggered fears of a hooch tragedy, but suspicion deepened after no other consumers who bought liquor from the same government outlet reported illness. Police said the post-mortem examination later confirmed cyanide poisoning, prompting a homicide probe. Officials said scrutiny of Pawan's mobile phone marked the turning point in the case. Police said the device allegedly contained repeated internet searches over nearly a month on cyanide, poisonous substances and ways to administer poison discreetly. Officials said the digital evidence became the central link in establishing premeditation, intent and criminal conspiracy. According to police, the alleged conspiracy involved Alka, sister of Ankit, her alleged lover Pawan and local goldsmith Ashok alias Soni. Police said the motive stemmed from prolonged domestic abuse and Ankit's opposition to Alka's relationship with Pawan. Investigators alleged that Ankit frequently assaulted his sister after consuming alcohol and had recently molested her while inebriated, after which she confided in Pawan. Police said Pawan then allegedly approached Ashok, who supplied cyanide for Rs.500 and told him that the chemical was commonly used in cleaning jewellery. Investigators said there was an earlier failed attempt to poison Ankit through food, but the plan was not carried out. The accused then allegedly shifted to a second, more lethal plan involving a tetra pack of country-made liquor. According to police, Pawan allegedly procured the liquor pack through a local youth, opened it, mixed cyanide into it and carefully resealed it with adhesive tape before handing it over to Ankit. Police said Ankit later consumed the liquor along with Baburam and Jitendra, after which all three collapsed and died during treatment. Officials said the digital trail from the mobile phone, coupled with forensic findings and interrogation inputs, helped reconstruct the alleged planning, procurement and execution of the crime....
