Following the ceremony, Wortham's father, Thomas Wortham III, said Chicagoans and the nation as a whole need to consider those who are committing acts of violence.
"We need to think about the people who are down and out," he said. "We can no longer ignore those people because they will continue to kill us."
"He was truly a born leader," Mayor Richard Daley told the assembled crowd. "He is an example of an ideal police officer here in our great city."
The officer's star, number 6181, joins those of 477 other police officers in a case of honored heroes in the lobby of police headquarters.
"This is too much killing," Wortham's father said. "We would like to say at this point, that we would hope that there would never be another star placed in that cabinet."
Wortham was a member of the Wisconsin National Guard who served two tours of duty in Iraq. He joined the Chicago Police Department in 2007. His family has lived in the South Side Chatham neigborhood for about 30 years, where they have been active in efforts to curb street violence.
"When people think of the South Side of Chicago, they think violence. In Chatham, that's not what we see. It's happened, and we're going to fix it, so it doesn't happen again," he said in an interview.
