The four battalions of the Criminal Investigation Detachment of Baoding City Public Security Bureau immediately dispatched elite police forces to fully investigate with Anxin and Qingyuan police. After work, Qingyuan police found some copper materials loaded on the missing semi-trailer from a waste collection station in the jurisdiction, and retrieved the images of people who came to sell copper materials from the monitoring of the station.
Under the strong pressure of the police, at 6 o'clock in the morning of March 7, Wang Jiao, his sisters Wang Ling and Ran Li, who felt exposed, surrendered themselves to Qingyuan Public Security Bureau, and told them that on the evening of March 3, together with five other people, they pretended to be public security personnel to intercept and hijack a large truck at the southbound intersection of East Third Ring Road and Baoxin Road in Baoding, and took two drivers to Wang Jiao's brother's pig farm for beating, and then injected ether into them to kill them, and then they died.
After receiving this situation, Zhang Jinzhong, deputy head of qingyuan county, public security bureau chief and Cui Xinyong, political commissar attached great importance to it and asked the task force to capture all the suspects and eliminate the social impact in time. On the evening of March 7th, around 1 1, the police of the task force successively arrested the suspects Duan Chao, Mary, (16 years old) and (17 years old). At 5 pm on March 8, Zheng Yi was arrested in a rented house in the new urban area of Baoding.
After the trial, five suspects, including Duan Chao, confessed to the crime of robbery and murder with four people, including Wang Jiao. At this point, the "March 3" extraordinarily serious robbery and murder case was successfully solved, and all nine suspects were arrested and detained in criminal detention, and the robbed copper materials and trucks were recovered.
After successfully detecting the "3.3" robbery and murder case, dozens of family members of the two victims could not afford to kneel in front of the police.
