RUTLAND, Vt. (AP) – The convicted killer of a 17-year-old boy is asking a judge to throw out a lawsuit against him because he has no money and is already being punished with his prison sentence of 20 years to life.

William Kapusta Sr., 58, pleaded guilty in December 2003 to two counts of second-degree murder for killing his ex-wife Teresa Jaworski, 39, and her son, Frank Brophy, 17, both of Danby, on Feb. 15, 2003.

Kapusta was sentenced as part of a plea deal to serve 20 years to life behind bars.

Frank Brophy’s father, Michael Brophy, filed a wrongful death lawsuit earlier this year in Rutland Superior Court seeking unspecified monetary damages against Kapusta.

Kapusta, acting as his own lawyer, later filed a response to the lawsuit. Kapusta asked Judge William Cohen to dismiss the lawsuit and, if he refuses, to appoint an attorney to represent him in the case.

In his response to the lawsuit, Kapusta “stipulates” that on Feb. 15, 2003, he “did wrongfully cause the death of Frank H. Brophy, by shooting him to death in the residence he shared with his mother, the late Teresa Jaworski.”

Kapusta added that in the criminal case against him he reached a plea deal with prosecutors that called for him to serve 20 years to life, in order to spare the families.
