A day after being arrested for stabbing his wife to death, boxer Edwin Valero was found dead in a jail cell.

The 28-year-old hanged himself, using his clothes, according to an AP report. An attempt was made to revive him, as he still had a pulse, the report said, but Valero succumbed.

Valero had been arrested Sunday after police found the body of his 24-year-old wife Jennifer Viera in a hotel in the city of Valencia, Venezuela.

The free swinging boxer had held the WBA super featherweight and currently held the WBC lightweight titles.
