Soon, Qinzhou City Public Security Bureau once again formed a special task force, fully advancing the work of solving the case.
A new round of thorough investigation was launched, centered on the crime scene, aiming not to miss any possible clues in the surrounding areas.
Unlike before, this time the investigation specified more detailed selection criteria: the target was males, approximately 1.70 meters tall, possibly suffering from male-related diseases, and showing signs of being left-handed in daily life.
Thanks to the police force's efforts in recent years to promote the "one standard, three realities" basic information collection system, the entire investigation process proceeded relatively smoothly.
This system has essentially achieved comprehensive database management of actual population, actual housing, and actual units within the jurisdiction.
