GENEVA (AP) _ The former Swiss boxing champion, Walter Blaser, stabbed his wife to death in the cafe where she worked, then committed suicide with the same knife, police said Saturday.

Blaser, 41, killed his 29-year-old wife Marie-Luce on Friday night, according to police, who gave no motive for the boxer's action. The couple had been married six months.

Blaser was held under investigative custody from January to June after he injured a policeman, who he alleged was trying to harm his future wife, Swiss newspapers reported Saturday. They said the couple was married in May, while Blaser was in jail.

Blaser was the Swiss featherweight champion from 1972 until he retired in 1975 after losing the European championship match to Jose Ramon Gomez Fouz of Spain.

During his six-year career, he won 27 of his 29 bouts, scoring knockouts in 15 of them.
