Oishee Rahman before a Dhaka court yesterday confessed to her involvement in the recent killing of her parents -- Special Branch police inspector Mahfuzur Rahman and his wife Swapna Rahman.
"My client Oishee is a mental patient. Police influenced her to give confessional statements," defence lawyer Prakash Ranjan Biswas told The Daily Star by phone.
The defence will file a petition to withdraw her statements, he added.
Oishee, the couple's house help Khadiza Khatun Sumi and Oishee's friend Mizanur Rahman Rony, who had allegedly helped her stay at one of his aunt's place after the murder, were produced before the Dhaka Chief Metropolitan Magistrate court on completion of their five-day remand yesterday noon.
Metropolitan Magistrate Anwar Sadat recorded the confessional statements of Oishee and Sumi under the section-164. Oishee and Sumi were then sent to the National Juvenile Development Centre at Tangi, Gazipur.
The defence filed two petitions seeking Oishee's bail and court's permission to visit the crime scene. Through two other petitions, they also prayed to the court to arrange for her treatment, claiming that she was sick, and to pass the case to a juvenile court.
The court fixed today to hear the petitions.
Rony was placed on fresh five-day remand for further interrogation.
At a press briefing at the Dhaka Metropolitan Police media centre, Joint Commissioner Monirul Islam in the afternoon said that before making the confessional statements, she had told detectives she alone killed her parents.
Oishee had her parents drink coffee mixed with 60 pieces of a sedative and stabbed them to death in the early hours of August 15 after they became unconscious.
Sumi only helped her move the bodies to a bathroom at her Chamelibagh residence in the capital, Monirul added.
The DB official also quoted Oishee as saying that her parents had curtailed her “freedom” and that was why she had killed them.
She might have taken directions or advice from others and detectives are looking into the matter, Monirul said. The whole incident will become clear after the finger print report and DNA tests of the samples from Oishee's bloodstained clothes are done and also after the arrest of the other people, if any, who had direct or indirect links.
Regarding the age controversy, he said Oishee's age was mentioned as 17 in the case document but she had told detectives that she was now 18.
"She was taken to Dhaka Medical College Hospital for tests to determine her biological age. The court will decide whether she will be tried under the common law or the special law for children," Monirul said.
On August 16, the decomposing bodies of the couple were recovered from their Chamelibagh residence.
Twenty-two hours later, their teenage daughter showed up at Paltan Police Station. DB police arrested her friend Rony and house help Sumi the same day.
