Mindy McCready's arraignment on criminal charges in Kingman, Ariz., has been postponed until Aug. 30. One of the singer's representatives asked the Mojave Country district attorney's office to agree to the delay prior to a court appearance originally scheduled for Friday (July 29). McCready is charged with unlawful use of transportation and hindering prosecution in connection with an alleged con scheme. McCready was released from a Florida hospital on Tuesday (July 26) after an overdose of drugs and alcohol. The singer reportedly left a four-page suicide note before being found unconscious in the lobby of a Holiday Inn near Tampa.
