WINNIPEG - A man who is accused of killing a Winnipeg woman eight years ago laughed as he tried to plead guilty to second-degree murder today.

Traigo Andretti is already serving a life-sentence for killing and dismembering his wife in British Columbia.

He was charged in the Winnipeg murder while in jail in B.C., and was brought back to the Manitoba capital to face charges of killing Myrna Letandre in 2006.

Andretti has refused to meet with a lawyer several times and told Judge Tim Preston he wants to plead guilty.

Letandre's sister sobbed in the courtroom as the 38-year-old laughed while his case was discussed.

Andretti is scheduled to formally enter a guilty plea Sept. 10.
