PHOENIX -- The Phoenix police chief called on a radio talk show host to apologize for making disparaging remarks regarding a slain officer's wife.

KFYI talk show host Bruce Jacobs criticized Julie Erfle -- the widow of Officer Nick Erfle -- for advocating what police call a "reasonable immigration policy." Jacobs said she is pushing for an illegal immigrant amnesty program.

Nick Erfle was killed in the line of duty in September 2007 by an illegal immigrant he was trying to apprehend.

"I'm really kind of ashamed for Julie Erfle, too," Jacobs said in Thursday's broadcast. "To be honest with you, I'm ashamed for her to advocate policy that will lead to more murders of innocent people, including police officers. And really, in my view what she's doing is just a slap in the face to what her husband did, which is to uphold public safety and stand for the law."

Jacobs went on to say that Erfle's husband would be ashamed of her and blamed her for future crimes committed by illegal immigrants.

"When the next police officer is gunned down or killed, is it fair to blame you?" he asked. "Because I am going to give you partial blame. Put that in your legacy for your husband."

Police Chief Jack Harris called the attack "unacceptable," saying that police "will not stand for it." Harris also said his support of Erfle's family is not about immigration, but about protecting police officers and respecting their families.

Harris wants Jacobs to give Erfle a formal written apology as well as apologize on the air. He said he was disappointed with not only Jacobs but also KFYI and Clear Channel, the station's parent company.

Since Jacobs made his on-air remarks, two sponsors -- McDonalds and Casino Arizona -- have dropped their support of the show.

The police department said it is not advocating a boycott of Jacobs or KFYI, and it is not pushing sponsors to drop their support.

Erfle just returned from a trip to Washington, D.C., to speak at a Police Foundation conference on illegal immigration's effect on local law enforcement.
