Federal authorities have ruled out suicide in the disappearance of a missing hedge-fund swindler whose car was found on a New York bridge with the words “Suicide is Painless” written in the dust on the hood.

U.S. Marshal Joseph Guccione said Monday that investigators now consider the case of Samuel Israel III to be solely a fugitive investigation.

Israel’s car was found a week ago on a Hudson River bridge.

Federal marshals issued a wanted poster Thursday for the man convicted of cheating investors out of $450 million in his Bayou hedge funds. They said he should be considered armed and dangerous.

Israel disappeared the day he was supposed to begin a 20-year prison sentence.
