Michi Nogami-Marshall was arrested Friday after a "verbal dispute" at the couple's home in Southwest Ranches, Fla., according to the Broward County Sheriff's Office arrest report, CBS4 Miami reported.
The Sheriff's Office reported that deputies responded to a 911 hang-up at the couple's home Friday morning. Despite a protection order requiring her to stay at least 500 feet from the home, Nogami-Marshall, 27, told deputies she had been living there while Marshall was out of town. When Marshall returned, an argument occurred, followed by the 911 call.
There was no sign of physical violence, deputies said.
"Clearly, the arrest today -- based on her actions, she had to be taken into custody because she violated a court order," Broward Sheriff's spokeswoman Veda Coleman-Wright told CBS4 Miami.
Nogami-Marshall was charged with aggravated battery with a deadly weapon after she allegedly stabbed her husband in the stomach with a kitchen knife on April 22. According to the arrest report, she admitted stabbing Marshall but said it was in self-defense. The Broward State Attorney's Office said in a statement that it was still investigating the incident.
Neither Marshall, who required surgery and was in intensive care following the April incident, nor his wife were cooperative Friday, Coleman-Wright said, and the Attorney's Office said investigators have encountered difficulty as they pursue the case.
"Despite numerous efforts, we so far have been unable to get Mr. Marshall to agree to voluntarily speak to our office about the incident," the Attorney's Office said in a statement. "We continue to diligently pursue this matter."
Marshall initially claimed he suffered his stomach wound when he slipped and fell onto a broken glass vase, but the police report noted that there was "no blood within the immediate area to substantiate his claim."
The statement reads in part: "Despite numerous efforts, we so far have been unable to get Mr. Marshall to agree to voluntarily speak to our office about the incident. We continue to diligently pursue this matter."
