BHUBANESWAR: A day after Dr Brahmananda Panda’s gruesome murder, the police tried to link the evidence at hand with suspects and possible motives to arrive at any conclusion. A special squad, headed by Bhubaneswar Deputy Commissioner of Police Himansu Lal, was on the job but no arrests were made yet although there were reports that police had zeroed in on the killer. Sources said, police were trying to ascertain the role of a staff from whose possession cash and a necklace has reportedly been recovered. But it was not possible to pin him down with just that since valuables may or may not belong to the surgeon. Reports also pointed at some past staff but no clear picture emerged today. Still short of a clinching evidence such as an eyewitness or a murder weapon that could prove vital, the investigators kept questioning the nursing home staff, both current and past ones. All possible angles were being looked into. Past enmity and vengeance given the nature of the crime were topmost on the mind while theft as a reason was not ruled out either. “There is a fair probability that an insider is involved but it is too early to conclude anything. Besides, we have found it difficult to correlate any particular person’s involvement with the crime scene,’’ said a senior police officer. Since the murder was detected a good 10 hours after it was committed, the assailant(s)) had ample time to get rid of the evidence. The assailant(s) is believed to have cleaned himself in a wash basin in Panda’s flat after the crime.
