We noted that the attorney's failure to cooperate impeded investigation of the underlying allegations and showed lack of acknowledgement of the seriousness of the allegations. See id. at 907. We have also indefinitely suspended attorneys who engage in a pattern of neglecting client matters, failing to communicate with clients, and failing to cooperate with a subsequent investigation. Respondent did not appear at oral argument before us and has not presented any evidence of mitigating circumstances that would warrant a lesser sanction. His complete lack of cooperation in the instant disciplinary investigation and his previous disciplinary history including an admonition for noncooperation lead us to the conclusion that indefinite suspension is the appropriate sanction for respondent's misconduct.
Indefinite suspension is ordered.
Such requests shall not be disproportionate to the gravity and complexity of the alleged ethical violations.
