From 1989 up until his arrest in September 1994, Luo would drive around the
Tianhe District with his truck, picking up at least 260 prostitutes in the process. As a
rule of thumb, he would immediately kill any who resisted his advances, asked him to wear a condom, did not allow him to have sex with them twice, or checked his license plate. On the evening of February 7, 1990, Luo drove around for about two hours around the Xinzhou section before he picked up a young woman, whom he then drove to the Pazhou Dairy Farm. There, he began raping her, but as the woman fiercely resisted his advances, he killed her,
raped her body and then dumped it by the roadside of Dunhe Road. He went to check if somebody had found the body on the next day, and for a while, he was paranoid that the police would come and arrest him. As time passed by, however, Luo became convinced that the authorities only investigated those who were in intimate relations with the victims, which naturally excluded him as a suspect. From February 1991 onwards, Luo continued to carry out murders, always late at night. He would then transport the corpse with his truck and carry it to the attic, where he cut off the victim's
vulva, shoved panties and socks into the vaginal area and even left his
semen inside to see if the police would be able to detect it. Once he was finished, he would put the corpses in burlap sacks, oil drums or wooden boxes, then drop them off in isolated sections of
Xinjiao Town. He was caught doing this by his wife on one occasion, but lied to her that he was in a fatal car crash and this was the body of the other driver. Luo claimed that his success in concealing himself gave him a sense of pleasure and he felt like he could do whatever he wanted. After each murder, he would write down the victim's physical features, clothing, sexual experiences, his own feelings and the process of disposing the body in a notebook, which he would later re-read for his own gratification. Later on, after hearing that the security organs' investigation of the crimes was tightening, he destroyed the notebook, but re-wrote the contents in another way. On May 25, 1992, Luo was suddenly arrested in the middle of the night by police officers in the Tianhe District, who charged him with soliciting prostitutes. For this, he was sent to a labor camp for six months, during which he saw an emergency investigation report by the Municipal Public Security Bureau on the crimes. Fearing imminent arrest, he managed to escape from the camp but ceased killing for nearly half a year. He resumed his activities in March 1994, killing an additional four prostitutes until his arrest in September of that year. ==Investigation==
