Wang had been a fugitive since 1998, when his estranged wife and her son were both murdered in suburban Los Angeles. The crime was later profiled on "America's Most Wanted."
Lieutenant Kim-Toy Huh, who speaks Mandarin, was on hand to translate during the arrest.
"He was on "America's Most Wanted," and then we got additional information from that. He said he was who we were looking for, he knew that, then he went peacefully with the officers," said Lt. Kim-Toy Huh, Chicago Police.
The suspect made a court appearance Monday. But the judge continued the extradition hearing because a Mandarin interpreter was not available.
For now, Wang is being held without bail.
