The Ghanaian admitted to the crime on Wednesday after being stopped by the police at the Milan train station having fled his home upon killing his 43 year-old mother, Nfum Patience and sister, Magdalene Nyantakyi on Tuesday night.
His brother named, Raymond Nyantakyi had found their bodies stabbed to death after he returned home from work.
The 21 yr-old midfielder was a very promising prospect in the Parma youth academy until their bankruptcy in 2015.
“I remember Solomon, he trained with us at Parma and I had him on the bench more than once during Serie A games,” said former Parma Coach Roberto Donadoni, who now coach Bologna, in a Football Italia report.
“I remember he was very calm, even taciturn. If it really was him who did this, I can’t think what went through his mind. He was a midfielder in the Parma youth academy, then I don’t know what path he took after the bankruptcy."
