Attorney Joseph F. Krowski served as lead defense counsel in Commonwealth v. Kater (2000), a landmark Massachusetts Supreme Judicial Court case involving the retrial of James M. Kater, accused in the 1978 murder of Mary Lou Arruda. The case drew statewide attention due to its complexity, emotional weight, and decades-long history. Krowski argued critical constitutional issues and helped define procedural standards for retrials, demonstrating his deep commitment to due process and vigorous defense in even the most high-profile and challenging cases.

In a widely publicized Bristol County trial, Attorney Joseph F. Krowski defended Karen Robidoux, a young mother charged with second-degree murder following the religiously motivated starvation of her infant son. As a member of a controversial religious sect, Robidoux’s mental state and control by the group were central to the defense. Krowski’s efforts led to her acquittal on the murder charge and conviction on a lesser offense. The outcome reflected his ability to contextualize intent and secure just outcomes in emotionally charged cases.

Attorney Joseph F. Krowski secured a major win in Commonwealth v. Rosario by proving police misconduct had tainted a search warrant. Representing Jimmy Roman Rosario in Hampden County, Krowski successfully argued that the affidavit supporting the warrant contained falsehoods, leading to the suppression of key drug evidence. The Commonwealth’s appeal was later abandoned, and the state charges were dropped. The case highlighted Krowski’s command of evidentiary hearings and his relentless pursuit of justice when constitutional rights are violated.
