Charles Marsico, the half-brother of former world lightweight boxing champion Paul Spadafora, died July 4, officials have confirmed. He was 40.

Officials said they believe he died due to a "suspected overdose."

Marsico was found inside a family home in the West End on Kearns Avenue in Pittsburgh.

Spadafora is in jail after he was arrested in December. He was accused of stabbing Marsico during a fight.

"I love him, but he stabbed me, and I didn't even do nothing to get stabbed," Charles Marsico told Pittsburgh's Action News 4 after the incident. "But my feelings ain't going to change for him. He just needs help, that's all I know."

At the time of the incident when Spadafora was arrested, Police saw broken ceramics, pots, pans and utensils on the ground outside Spadafora's house, and he was yelling at his mother and pacing on the front porch when officers approached the residence in the city's Westwood neighborhood, according to the criminal complaint.

"Everything in the house is all broken from him throwing things," Marsico said. "My mother, she tried to have Christmas, it was all nice and all that, and he wants to come home, I guess, and start trouble."

Spadafora, 41, refused officers' commands not to re-enter the house after Marsico met them in the driveway, showed them a wound to his upper right thigh and said, "He did it," according to the complaint.

"I was lying down on the couch, and the next thing you know he's throwing things at me, and I'm like, 'What are you doing, Paul?' And then after that, he just stuck me with one of his knives," Marsico said.

According to the complaint, police were finally able to get the combative Spadafora on the ground and carry him down the front steps after using pepper spray and Tasers.

Spadafora's mother told police that he had "come home high and was mad at Charlie, they started fighting and Paul stabbed Charlie," according to the complaint.

Spadafora's championship career was derailed by multiple arrests beginning in the early 2000s. He relinquished his world title after shooting his girlfriend in McKees Rocks in October 2003 and served time in a prison boot camp.
