A Central Bureau of Investigation team led by DIG Hemant Priyadarshi on Monday visited the residence of slain Madhya Pradesh RTI activist Shehla Masood in Bhopal and recreated the sequence of events that led to her murder.
The team, which reached Masood's house around 11 am recreated the scene of the killing, which took place outside her residence last month.
It examined the car in which Masood was shot dead and a man was made to sit in the vehicle to find out the possible angles from which she may have been shot.
Priyadarshi told reporters this was a murder which was very challenging for the CBI as no clue or eyewitness has been found in the case so far.
Members of the CBI team are holding discussions in connection with the murder with her family, he said.
The DIG said some evidence has been found but it would not be proper to disclose it at this point of time.
Asked how much time it would take to solve the case, the officer said that it was not possible to give particular a time-frame.
Masood was shot dead when she was going towards her car outside her home in Koh-e-Fiza locality here on August 16.
The Madhya Pradesh government had sought a CBI probe into the murder.
