Spadaccini was arrested last September after he brought a 14-year-old boy to the Packer Avenue Holiday Inn in South Philadelphia and gave the teenager a cocktail of vodka and orange soda spiked with the prescription drug Xanax. Spadaccini admitted that he knew the drink would render the boy unconscious, McNabb said.
A 13-year-old boy came forward after the arrest and said that he was given drugs and alcohol and had sexual contact with Spadaccini multiple times in July and August 2011, at the same Holiday Inn and Spadaccini's home.
At his home, Spadaccini gave the boy orange drink and vodka, fondled the victim and exposed himself. While at the hotel room, Spadaccini gave mixed drinks to the victim and sexually assaulted the boy after the teenager consumed the drink.
McNabb said she expects a sentencing date sometime in early January 2013. Spadaccini remains held on $2 million bail.
She credited the resolve of the victims in helping put Spadaccini away.
"The cases showed the strength and courage of two young boys to ensure" a conviction, McNabb said.
McNabb added that the case was worsened by the fact that trust was placed in the defendant.
"Lou was respected in baseball and in the court community and had a lot of trust instilled in him by the families," McNabb said.
The case was heard in front of Chester County Judge Ronald Nagle because Spadaccini was a former employee of the city courts.
Spadaccini coached baseball at Saints John Neumann and Maria Goretti Catholic High School for five seasons.
His lawyer, Tariq Karim El-Shabazz, could not be reached for comment.
