A key witness in the trial, Vincenzo Marino, made the shocking revelation in court. Marino had been detained in prison at the same time as Oseghale and claimed to have overheard him admit to the murder.
According to Il Giornale, Marino said that the Nigerian drug dealer stabbed the Italian teen immediately after having sex with her. “They had a fight, they pushed, Oseghale stabbed her in the liver and after a first stab Pamela fell to the ground,” he said.
The witness went on to add that following the initial stabbing, Oseghale left the scene to fetch another man to help him dispose of Mastropietro’s body and then “returned home, convinced him that Pamela was dead and started dismembering from the foot.”
The Nigerian is then alleged to have stabbed the teen again after she allegedly tried to cry out.
According to Marino, Oseghale did not name who his accomplice was. “He had washed [the body] with bleach because it would not have been known if she had died of an overdose or murdered,” he said.
“He said there was a sack in the fridge to put the pieces in, but they did not fit in there and that he had to cut it and put it in two suitcases,” Marino added.
The suitcases, which were left on the side of the road, were discovered in February last year in the Italian commune of Pollenza sparking a national uproar and provoking a mass shooting attempt targeting migrants by 28-year-old Luca Traini, who allegedly knew the victim.
Several months later, another Italian teen, Desirée Mariottini, was found dead following an overdose in Rome. Prosecutors arrested several migrant men in connection with her death accusing them of raping the 16-year-old and purposely causing her to fatally overdose on drugs.
