Michael Memeo, 46, made an initial court appearance Wednesday at the Nesbett Courthouse on charges of murder and tampering with evidence.
Memeo stands accused of killing Irma Williams, a woman whose family reported her missing on Sept. 30. She had not been seen for two weeks, police said. Williams' body was discovered Oct. 15 near Lions Park in Anchorage's Mountain View neighborhood.
He appeared in court wearing orange Cook Inlet Pre-trial Facility garb and did not speak during the brief arraignment.
A court document offered few details about the evidence that led to charges of first- and second-degree murder and tampering with evidence.
Superior Court Judge Philip Volland entered not guilty pleas for all of the charges on Memeo's behalf.
According to testimony, Memeo has had a public defender appointed in an unrelated probate case. Bail has been set at $500,000 cash performance and a third-party custodian in the murder case.
The indictment, provided by the Anchorage District Attorney's Office, alleges Memeo "intentionally caused the death of Irma Williams" on or about Sept. 14, two weeks before her family reported her missing.
He also allegedly destroyed, altered or concealed evidence of the crime, intending to impair a criminal investigation, according to the felony tampering with evidence charge.
Memeo's next court appearance was set for Feb. 2. His trial was scheduled for March.
