A New York man accused of killing his hedge-fund founder father over a cut in his allowance has been found unfit to stand trial.

A judge ruled Thursday that Tommy Gilbert isn't mentally fit to proceed to trial. He is to be sent to a psychiatric hospital next week, unless prosecutors ask for a hearing.

The 31-year-old is accused of shooting Thomas Gilbert in January and then trying to make it appear as if his 70-year-old father killed himself.

Authorities suspect Gilbert killed his father after he was threatened with a cut in his monthly allowance. Gilbert's mother found her husband's body in their Manhattan apartment.

Thomas Gilbert founded the Wainscott Capital Partners Fund.

A lawyer for the younger Gilbert says he hopes his client gets the treatment he needs.
