BUENOS AIRES, Argentina—Mystery in the gunshot death of a prosecutor who had accused Argentina’s president of covering up a terror attack deepened Wednesday with the revelation that a door to his apartment barely locked and the discovery of another previously unknown entry.
The locksmith who opened the back door to give investigators access to the home where Alberto Nisman was found dead said it was barely closed, raising questions about whether a killer might have entered or exited what was earlier described as a 13th-story apartment locked from the inside.
After testifying to investigators, the man who gave his name only as Walter said he was able to quickly open the door with a hook. He added, “If someone entered or not, I don’t know.”
