The Federal Bureau of Investigation has sent to Bangladesh Police the DNA test results of 13 samples collected from the crime scene where secular writer Avijit Roy was killed last year.
“The FBI has sent us full DNA profile of 13 samples we gave them on March 11 last year,” a highly-placed source in the police told the Dhaka Tribune last night seeking anonymity as he is not authorised to speak to media.
The results came around two weeks ago, the official added.
The evidence include two machetes, one blood-stained shirt, papers, jeans pants, a pair of black sunglasses, pieces of Avijit’s nails, one long strand of hair and a black schoolbag left by the killers.
US citizen Avijit Roy, also a former lecturer of Buet, and his wife Rafida Ahmed Bonya came under attack near the TSC intersection of Dhaka University in the night of February 26 when they were returning from the Amar Ekushey Book Fair.
The couple was critically injured in the machete attack while Avijit, the founder of secularist Mukto-Mona blog, was declared dead at the hospital.
Banned militant outfit Ansarullah Bangla Team or Ansar al-Islam, believed to be representing al-Qaeda in the Indian Subcontinent (AQIS) in Bangladesh, claimed responsibility for the murder.
The Dhaka Metropolitan Police on August 21 released several pieces of CCTV footage of six suspected killers. In the footage, the suspects were seen following the couple at the book fair.
