Thiruvananthapuram: The investigation team, probing into the sensational serial murders in Kozhikode, would be expanded, said Kerala Police on Tuesday.
Kerala DGP Loknath Behera told media here that the forensics in the case would be sent abroad for ‘best laboratory’ examination.
Also, the police would seek the court’s permission for ‘trace analysis’ in the best laboratory in the nation. Trace analysis could help detect or study trace evidence.
Meanwhile, police decided to summon Rojo Thomas, Jolly’s former brother-in-law from the US for more details.
Rojo was the one to lodge a complaint with the police seeking investigation into serial deaths in his family.
Police would quiz former sub-inspector Ramanunni who was in charge when Roy Thomas, Jolly’s former husband, had died.
His post mortem report had reportedly shown traces of cyanide but was not investigated.
Meanwhile, CPM expelled K Manoj, the local committee member, who was questioned by the police over his connections with Jolly.
He has been accused of helping Jolly prepare a fake will of her father-in-law's.
