LOS ANGELES — A Rockefeller impostor convicted in a California cold-case murder appeared in court as his own lawyer Tuesday and failed to delay his sentencing.
The judge said Tuesday he saw no reason to put off Christian Gerhartsreiter’s Aug. 15 sentencing date. Gerhartsreiter could be given a sentence of 27 years to life in prison.
Gerhartsreiter said he wanted to go over trial transcripts to find legal errors, but the judge said that would be ‘‘a fishing expedition.’’
Gerhartsreiter acknowledged he was a novice in the business of representing himself and took a break to talk with his former Boston lawyers by phone.
He returned and said he believed if given enough time, he could prove that ‘‘the evidence is insufficient to support the verdict.’’
