According to Hesari, he was:
HS 1.10.1994
Let's look at that snipped again: "Captain Pihti has been questioned by the Estonia Crash Investigation Commission, Bengt Erik Stenmark, head of security at the Swedish Maritime Government, said on Friday. However, the investigatory panel on Friday disputed Stenmark's information."
(There may have been some autocorrect accident with Piht's name as "pihti" is a Finnish word).
So, according to that snippet Stenmark told that the commission had interrogated Piht. And the second sentence says that the commission themselves say that they have never done that.
In a longer context that article does not say that Piht is alive. Even the header reads: "There are many different versions of captain Piht's fate".
In summary, the first paragraph states that Swedish and Danish newspapers have reported on 30 September that Piht has vanished from a hospital in Helsinki and that they claim to have gotten the information from Helsinki Police. The official survivor lists don't have Piht so according to them he is dead.
Then comes the paragraph that Vixen quoted above.
The third paragraph states that Helsinki criminal police has talked to survivors that were brought to Helsinki on ships. Pauli Kokko from police states that he can't remember any Piht from the group but that they had time to talk only to about half of the approximately 40 survivors.
The fourth paragraph says that identifying the dead is a job of Turku police. The chief of the western area criminal police Kurt Alopaeus tells that the last reliable observation of Piht was round midnight before the accident on the bridge of Estonia.
In the final paragraph Alopaeus tells that they have tried to check all information about Piht but that they haven't been able to confirm that he is alive but that they can't be certain that he is dead.
