Alexander J. Boik, an 18-year-old known as AJ, had a reputation for making people laugh and tried to bring back the mullet hair cut in his freshman year of high school.
"He tried to rock the mullet," said Tyler Lynch, 20, who played baseball with Boik on their high school team. Boik, a catcher who played on the team through his junior year, had recently graduated from Gateway High School in Aurora. He also played in the school orchestra.
