POTSDAM â Katherine Mary âKatyâ Hawelka â she was the peacemaker. When Katy died in 1986, she was 19, the second oldest of four children raised in Central New York. Joe was 16, Carey 17, and Betsy 21. âWhen somebodyâs passed, you always say these wonderful things about them,â Carey Hawelka Patton said. âBut theyâre true.â The kind of sisters who are best friends, Carey and Katy were almost inseparable through adolescence at Henninger High School in Syracuse. Quarrels among the siblings were often broken up by Katy, whose smile was as exceptionally warm as her wit was sharp. Graduating from Henninger, Katy headed 142 miles north to Clarkson University in Potsdam to study business. The day after arriving for her sophomore year in August 1986, Katy was attacked, beaten, raped and strangled outside the universityâs Walker Arena. She died three days later on Sept. 1, Watertown doctors declaring her brain dead and the Hawelka family agreeing to discontinue life support.
