The woman charged in the stabbing death of Douglas Richt is now being held on $1 million bond.
Jodie Sherman is charged with first degree murder. She is expected back in court for a preliminary hearing on July 17.
The incident happened around 12:30 p.m.
Witnesses say Richt and Sherman began to argue in his vehicle.
"They were arguing, they were calling each other names, they were fighting basically," said Shyanne Matthews, who saw the argument from her grandmother's porch. Sherman had been living with Matthews' grandmother, Carolyn Brown, for two years.
Matthews says she saw Sherman strike Richt, and then he got out of the vehicle and tried to crawl to the porch of the residence, bleeding from his neck. Sherman fled on foot.
"All of a sudden I hear, 'she stabbed me,'" said Matthews.
Authorities found Richt on that porch. He had a stab wound to the neck. He was pronounced dead at the hospital.
"It just happened so fast I couldn't even comprehend it--it was just shocking that that stuff would happen," said Harley Eshelman, who was also sitting on the porch with Matthews.
Sherman was arrested shortly afterward.
Sgt. Dave Dawson, with the Criminal Investigation Division, said, "Basically, we got a call of a rolling disturbance down here. We have one suspect in custody. We have a victim that is deceased. At this point we're working the investigation to see what the circumstances are around it."
Sherman is being held without bail at the Pottawattamie County jail.
