Mary Baymiller, 72, was arrested Wednesday and charged with murder with use of deadly weapon in connection with the stabbing death of 73-year-old Charles Baymiller.
Officers from the U. S. Marshals Fugitive Task Force made the arrest without incident at Baymiller's residence in Fresno, Calif., at the request of the detective division of the Washoe County Sheriff's Office, according to Sgt. Greg Herrara.
A warrant for the arrest was obtained early Wednesday morning through the James A. Mancuso Justice Court. The degree of murder - first, second or third degree - was not specified.
"Mary Baymiller will be extradited to Nevada to stand trial," said Herrara. "The investigation was completed earlier in the week and officers concluded there was enough evidence to make an arrest."
The arrest stems from an Oct. 5 incident that left Charles Baymiller dead and his wife, Mary Baymiller, in intensive care at Renown Regional Medical Center in Reno for nearly a month with multiple stabbing injuries, after an apparent altercation at the couple's Lakeshore Boulevard home in Incline Village.
Herrera confirmed in a November interview that multiple kitchen-type knives were used in the incident, and it was previously reported Charles Baymiller's wounds did not appear self-inflicted.
County investigators launched a homicide investigation shortly after Mary Baymiller's release from the hospital, Herrera said, to determine if she had any involvement in her husband's death.
Herrera said in a December interview that the unique nature of the case resulted in a more meticulous investigation, accounting for the unusual amount of time between the incident and the arrest.
"This is a unique case," Herrera said. "The investigation has proceeded differently in terms of not making an immediate arrest."
Herrara said details regarding an arraignment date and the exact charges filed by the District Attorney's Office in Reno are not immediately available, but will be released this week.
