In 1893, a subcommittee in the Senate was convened to hear evidence that Roach had embezzled money while acting as an officer of a bank.

Expulsion was considered, but the subcommittee decided the matter was too long past to take such action.

He died suddenly on September 7, 1902 while on a trip to New York City.
