Police on Monday said the bullet that killed journalist Soumya Vishwanathan was fired from outside the car but, seven days after the murder, said they had made no arrests.
Police would be questioning regular visitors at nearby pubs and discotheques in and around Vasant Kunj area where Vishwanathan was shot.
“We have a strong contention that Vishwanathan may have been attacked by some drunk men. They would have been speeding and when Vishwanathan refused to give them way, they would have opened fire to scare her, which proved fatal,” said a police officer.
Police said they had deployed several teams to check the movement of young men in the nearby “urbanised villages.”
“We are focusing on school dropouts and other regular party goers in nearby villages. We are in touch with locals who may provide us with clues,” said the officer.
Vishwanathan, a journalist with Headlines Today, was killed on September 30 as she was driving home from work.
She was found dead in her car around 3.30 am on Nelson Mandela Marg in Vasant Kunj. What earlier appeared to be an accident turned out to be cold-blooded murder when doctors found a bullet in her head.
On Monday, forensic experts said her car was in motion when she was attacked. They also told police hair strands found on the car’s backseat were that of Vishwanathan and fell there due to the “impact of the bullet”.
Forensic Science Laboratory (FSL) experts also said the killers were in the same carriageway in which Vishwanathan was driving and might have been trailing her.
“We have narrowed down on three motives, robbery being one of them. But it is too early to rule out anything else,” said a senior police officer.
Police said Vishwanathan was shot dead by a .315 bore country made revolver, generally used by “hardened criminals.”
“Almost all the witnesses who were traced by us or who approached us saw the incident after it had taken place. There is not a single person as yet who was there when Vishwanthan was shot dead,” said a senior police officer.
Police are yet to get an eyewitness in the case. “May be the eye witnesses is apprehensive and is not coming forward to help,” the police officer said.
