One of the suspects, surnamed Yang, had become the president of an unidentified company and he told police that the crime 28 years ago was a nightmare that lingered in his brain all these years.

“Throughout the years, this is the only thing that kept bothering me,” he was quoted as saying by the police.

The news release of the preliminary investigation also said the three were college classmates who visited Shanghai during the summer break in 1991.

After spending all their money, they decided to steal and bought a pry bar. The victims of the case were attacked by the bar after discovering the robbers.
