Gerold Stadler, 34-year-old husband of murdered skier Corinne Rey-Bellet killed himself, Swiss police confirmed on Thursday.
His body was discovered in a forest in the canton of Vaud, with a single gunshot wound to the head, late on Wednesday. A police spokesman said he had been dead for at least 36 hours. A gun was reportedly found at his side.
Stadler was wanted for questioning by police in connection with the murder of his estranged wife and her brother, Alain. They had been shot dead at the skier's home in Les Crozets on Sunday.
Corinne Rey-Bellet, 33, had left her husband almost two weeks earlier. A report in the Swiss German language tabloid Blick on Wednesday claimed she had been more than two months pregnant.
Stadler's body was found about 50km from the murder scene, at Huemoz, just above Ollon, 700m from where his car had earlier been found abandoned.
Witnesses reported hearing gunshots in the area mid-afternoon on Wednesday.
The funeral of Corinne and Alain Rey-Bellet was scheduled to take place at the church of Val d'Illiez yesterday. It is the same church where Alain was to be married on July 8 following a civil ceremony which was to take place yesterday, now the day of the funeral.
Corinne Rey-Bellet, who retired after winning the downhill silver medal at the 2003 world championships, won five World Cup races during her career and finished in the top three 15 times.
