MADISON, Wis. (AP) _ Police want to charge the son of Wisconsin football coach Barry Alvarez in the death of a parrot that was placed in a microwave oven.

Chad Alvarez, a 23-year-old senior, is accused of breaking into a fraternity brother's room and killing the bird.

Police recommend he be charged with burglary and mistreatment of an animal. Judy Schwaemle, deputy Dane County district attorney, said today she had not yet reviewed the case.

If charged and convicted on both counts, Alvarez faces a maximum fine of $20,000 and 12-year jail sentence.

Alvarez surrendered Friday and was released that day on a $500 signature bond. He pleaded no contest in April to first-offense drunken driving, according to court records.

Sigma Chi fraternity members found the parrot last week in the microwave while the oven was operating, police said.

Cory Greenfield owned the parrot and said whoever killed ``Iago'' may have done so because he was angry about an e-mail that was passed around the fraternity house.

``He thought I was ridiculing him in front of the whole fraternity,'' Greenfield told The Capital Times. But Greenfield said ``there's no excuse when you put somebody's pet in the microwave and fry it.''

Greenfield did not refer to Alvarez by name, but he said whoever killed his parrot had confessed.

Greenfield said the bird had a vocabulary of about 20 words. He said he locked his room last Tuesday, but someone could have used a master key to get in.

Schwaemle said Alvarez was tentatively ordered to appear in court Thursday, pending the decision on whether to issue charges.
