An argument over the noise made while watching a Mets baseball game sparked a fight that left a Queens, N.Y., woman bashed to death with a barbell — allegedly by her psychotic son, the New York Post reported.

The son, Michael Anthony told police that he had been fighting with his father when his mother, 61-year-old Maria Fischman, tried to intervene, the paper reported.

"My mother jumped in," he told police. "She went into the kitchen and got a knife."

Police say Anthony grabbed a 20-pound barbell after he thought his mom was going for a new weapon.

"[I] swung it, hit her and she fell to the floor," Anthony allegedly said, according to the Post.

Maria Fischman was found dead Saturday night in her sixth-floor apartment in the Pomonok Houses in Flushing, N.Y. The Post also reported that the woman had refused to have her son committed.
