Prati serial killer. Who helps the killer escape when the red Toyota IQ capsizes at the Magliana? And could the weapon found in the car, a kitchen knife apparently without bloodstains, be the one used for the crimes? Yet the coroner claims that the three women were killed with a long, pointed and well-sharpened blade. A stiletto. These are the things that don’t add up in the investigation that led to the arrest of Giandavide De Pau, the 51-year-old offender, toxic and psychopathic, accused of triple voluntary homicide and who this morning will appear before the investigating judge in the guarantee interrogation for the validation of the arrest . And from whom did he want to obtain a false passport to expatriate? An accomplice is being sought, someone who would have helped “il Biondo” to get away from the scene of the accident and reach the Cuban escort at Termini station. Not only. De Pau does not have a mobile phone, lost in via Riboty during the slaughter of the two Asian women. Element that suggests the presence of a second person since his arrival at the “massage center” a few steps from Piazzale Clodio. The first of two appointments with death, according to yet another reconstruction by the investigators. The former driver and factotum of the Camorra boss Michele Senese would have gone first to the two Asians, two women aged around 25 and 45. Then he would have reached the basement of via Durazzo 38 to meet, and kill, the 65-year-old Colombian, Martha Castano Torres. Did he know her? Had he already made an appointment with her? Yes, because in this phase of the tragedy that took place on Thursday, De Pau no longer has a cell phone. So the killer goes without fail, shortly after committing the double homicide. But the suspect does not agree with this accusation and even from the Regina Coeli isolation cell he continues to repeat that the Colombian, he, has not even touched her. “What’s the point of admitting two murders and denying a third?” Is the question he repeats endlessly during the 13 hours of interrogation in front of the mobile squad and the prosecutor, from 6.30 in the morning on Saturday to 19.30 when he comes out , in handcuffs, from San Vitale. A second killer, as already speculated? Among the things that don’t add up, the sequence of murders and the frames of the cameras. Is it possible to reverse the chronology of the crimes having acquired the dated frames and with the time well imprinted? From the outset, there was talk of the first red-light meeting in via Durazzo after 8.30, the time suggested by the sister of the Colombian victim, the 60-year-old transgender Maria. The woman claims that at that time she Martha had to meet someone. When she returns home at 12.30, she finds her dead. She was stabbed to death during intercourse, so much so as to believe in a deranged man with sexual problems. Then almost two hours of emptiness, until 10 when the Asians are still alive. At that hour there is nobody in the hall on the first floor, as several people testify. At 10.40 the youngest prostitute was found, naked and in a pool of blood. In the apartment the other, who intervened in her defense and was killed for this. But the hypothesised scenario is not credible, starting with that almost two-hour time gap in a space of just 800 meters between the scenes of the three crimes. But with the reversed sequence the “accounts” add up. Dense mystery about the motive and the presence of an accomplice. Today the task for the autopsies that will be performed at the Gemelli Institute of Legal Medicine will also be conferred.
