Taposh Sarkar, a student of Chattogram university, lost his life in a clash between two groups of Chhatra League over placing a wreath at the Buddhijibi circle in 2014.
He was a Chhatra League activist and a student of the Sanskrit department of the university.
It has been five years since Taposh was killed but the trial for his murder has not begun yet.
"My mother is still reeling from the shock of my brother's gruesome murder. We have not got justice yet while the killers are still dominating the campus. We have left all hope of getting justice," said Taposh's brother Srabon Sarkar.
Besides Taposh, 18 more died as victims of brutal political clashes between Chhatra League and Chhatra Shibir in the last 31 years, according to university sources.
Of the total 19 cases, one case has been dismissed in court as the charges against the accused could not be proved, while the other cases have not seen any progress.
Educationists and legal experts think loopholes in the legal system are letting perpetrators to stay at large.
"The main responsibility of law enforcers is to find evidence of the crimes. We expect fair, neutral and objective investigative reports from them. But their reports create controversy over the case, which delays justice," claimed social scientist and former Vice-Chancellor of Chattogram University Dr Iftekhar Uddin Chowdhury.
"The perpetrators have to be brought under law if proved guilty after investigation."
"We find delay in investigations and perpetrators are not punished in most cases. The number of campus killings are soaring due to loopholes in the legal system," he added.
"The investigations and trial cannot be progress for many reasons, for instance, for weakness in charge-sheets, transfer of investigation officer, absence or transfer of the magistrate who took statements of the perpetrators under section 164 in the magistrate court, absence of witnesses and experts," said Public Prosecutor of Chattogram metropolitan city Advocate Fakhar Uddin Ahmed.
At Chattogram university, the first political killing of a student took place in 1988.
