（三）供述情况
经审查，许汉省、张丽霞夫妇初步交代：2012年3月，夫妻二人来到北京市丰台区六圈菜市场租用西厅的两个摊位贩卖活鱼、冻鸡、冻鸭。同年5月，许汉省、张丽霞贩卖的活鱼多次被大量毒死。二人怀疑是自家摊位斜对面另一卖鱼的摊主苏要南下毒，后因此事双方发生争吵。5月中旬，二人将毒鱼一事向朋友李桂才提起，欲让李桂才帮忙报复苏要南。并将苏要南暂住地址告知李桂才，随即李桂才提出用镐把对苏要南进行殴打，或安放自制爆炸装置吓唬苏要南。7月12日凌晨，许汉省、张丽霞被警察抓获带离过程中，得知苏要南“出事”了。
李桂才初步交代：2012年5月中旬，李桂才在途经北京市丰台区六圈菜市场与卖鱼的摊主许汉省、张丽霞夫妇聊天时，张丽霞提到自家卖的鱼近期常被毒死，怀疑是自家摊位斜对面另一卖鱼的摊主苏要南下的毒，欲让李桂才帮忙报复。李桂才当时默许此事。7月初，李桂才萌生制作爆炸装置对苏要南、段文娟二人实施报复的想法。7月10日，李桂才在暂住地自家地下室内，利用在北京市丰台区北京花香祥发五金建材商店内购买的管箍、丝堵及自家的钉子、铅砂、火柴、火柴盒、春节剩余爆竹中的火药，制成拉发式爆炸装置一枚。7月11日21时许，李桂才潜至苏要南暂住地，将爆炸装置用白色线绳将自制爆炸装置捆绑在苏要南的三轮车左侧车把。后逃离现场返回暂住地。次日，李桂才得知苏要南被炸，直至被抓获。
根据嫌疑人交代，侦查员在李桂才暂住地及地下室起获黄色导线若干、剪断的钉子6枚、线夹、电钻、钳子、扳手、猎枪弹壳等物证，已送相关部门进行检验。
（四）处理情况

After investigation, the scene was located in the Pingfang District on the north side of the Liuquan Vegetable Market in Fengtai District, Beijing. The center site is located in the open space in front of a rental house in the middle of the bungalow area. A green electric tricycle was placed on the ground, and the corpse was lying prone with its head east and feet west, and it was located on the ground between the door and the tricycle. The deceased was naked from the upper body to dark jeans, and a large pool of blood could be seen on the ground around the body.
1. Frying point and material extraction
After investigation, the bombing point was located at the left handlebar of the electric tricycle parked outside the north gate of the rental house, about 1 meter above the ground. Two pieces of cast iron fragments and three stumps of single-strand white plastic wires were extracted from the body of the deceased. A number of black attachments were extracted from both arms, which were tested to be pyrotechnic powder explosion residue components. In the series of inspection materials extracted from the center of the explosion point, several cast iron fragments with threads, several spherical metal particles (lead-antimony alloy), three stumps of iron nails that were artificially twisted, and one handlebar of a charging tricycle were detected. (The handlebar is wrapped with a yellow single-strand wire, one end of the wire is connected to two white wires, and the other end of the white wire has traces of high temperature), some stumps of single-strand white plastic wires, and a jacket of the deceased.
2. Recovery of explosive devices
After splicing and calculating the cast iron fragments extracted at the site, the explosive device used at the site is a plumbing pipe fitting composed of a 40 mm diameter plumbing pipe collar and two plugs, with a volume of about 80 milliliters. The main charge is pyrotechnic powder, to which iron nail stubs and lead-antimony alloy metal balls are added. The detonation method should be a pull-type friction ignition detonation. After technical analysis, the suspect should hang the explosive device on the left handlebar of the tricycle, and possess primary explosive skills.
(4) Forensic medical examination
After forensic examination, the body surface of the deceased showed irregular distribution of wounds such as fragments of explosives, large-area abrasions caused by high temperature and shock waves, open contusions, and gunpowder smoke wounds.

Three, the process of solving the case
(1) The source of clues and the situation of capture
According to the deployment of the project team, when interviewing Xu Hansheng and his wife Zhang Lixia, both of them concealed that they had conflicts with the deceased Su Yaonan. And the situation of the people who were in contact with them on the night of the incident did not match the video, and the two were taken to the police station for review. After interrogation, there was a contradiction between Xu Hansheng's preliminary confession and the deceased Su Yaonan, and he had discussed with his friend Li Guicai that he should teach Su Yaonan a lesson. After retrieving the video at the time of the incident, it was found that Li Guicai was holding a white object in his right hand, entered the Liuquan vegetable market at 20:53 on July 11, and walked to Xu Hansheng's stall in the market at 21:04. During this period, there was a track missing for 11 minutes, and there was no white object in the hand when it reappeared. After on-the-spot inspection, it was found that there was only one passage leading to the explosion site at the location where its trajectory disappeared, and Li Gui was suspected of committing a major crime. After work, investigators arrested the suspect Li Guicai in Room 301, Gate 1, Building 1, District 1, Fujin Jiayuan, Fengtai District, at 13:00 on July 13.
(2) Basic information of the suspect

(3) Confessions
After examination, Xu Hanxing and Zhang Lixia made a preliminary statement: In March 2012, the couple rented two stalls in the West Hall of the Liuquan Vegetable Market in Fengtai District, Beijing, selling live fish, frozen chicken, and frozen duck. In May of the same year, live fish sold by Xu Hansheng and Zhang Lixia were poisoned to death many times. The two suspected that Su Yaonan, the owner of another fish seller diagonally across from their stall, had poisoned them, and then they had a quarrel over the matter. In mid-May, the two brought up the fish poisoning incident to their friend Li Guicai, and asked Li Guicai to help him avenge Su Yaonan. He also informed Li Guicai of Su Yaonan's temporary residence address, and then Li Guicai proposed to beat Su Yaonan with a pickaxe, or plant a homemade explosive device to scare Su Yaonan. In the early morning of July 12, when Xu Hansheng and Zhang Lixia were arrested and taken away by the police, they learned that something had happened to Su Yaonan.
Li Guicai's preliminary account: In mid-May 2012, when Li Guicai was passing through Liuquan Vegetable Market in Fengtai District, Beijing, chatting with fish stall owners Xu Hanxing and Zhang Lixia, Zhang Lixia mentioned that the fish she sold was often poisoned to death recently. It was Su Yao, the owner of another fish stall diagonally opposite his own stall, who went south to poison him, and wanted Li Guicai to help him take revenge. Li Guicai acquiesced to this at the time. At the beginning of July, Li Guicai had the idea of making an explosive device to retaliate against Su Yaonan and Duan Wenjuan. On July 10, in the basement of his temporary residence, Li Guicai used pipe clamps, plugs, nails, lead sand, matches, matchboxes, and leftovers from the Spring Festival purchased at Beijing Huaxiangxiangfa Hardware and Building Materials Store in Fengtai District, Beijing. The gunpowder in firecrackers is made into a pull-type explosive device. At about 21:00 on July 11, Li Guicai sneaked to Su Yaonan's temporary residence, and tied the explosive device to the left handlebar of Su Yaonan's tricycle with a white string. Afterwards, he fled the scene and returned to his temporary residence. The next day, Li Gui learned that Su Yaonan had been bombed until he was captured.
According to the suspect's confession, investigators found several yellow wires, 6 cut nails, wire clamps, electric drills, pliers, wrenches, shotgun shell casings and other physical evidence in Li Guicai's temporary residence and basement, and have sent them to relevant departments for inspection.
(4) Processing situation
At present, the suspects Xu Hansheng, Zhang Lixia, and Li Guicai have been criminally detained, and further examination, inspection and identification are in progress.
