LOS ANGELES (AP) - An Alabama man accused of murdering his wife while they were on their Australian honeymoon in 2003 has waived his extradition rights in California, and authorities have 30 days to return him to his home state.

Gabe Watson appeared in a Los Angeles court Tuesday, wearing a green hooded sweat shirt and khaki pants, and without handcuffs. One of Watson's attorneys, Brett Bloomston, told The Associated Press the 33-year-old waived extradition proceedings.

Watson served 18 months in an Australian prison after pleading guilty to manslaughter for the drowning of his wife, Tina Watson, during a scuba diving trip on the Great Barrier Reef. He arrived in California last week.

Prosecutors believe Watson devised a plan to kill his wife in Alabama before the trip, giving authorities there jurisdiction in the case.
