"I want him dealt with," Penny Larson allegedly said. "James told [the friend] to follow him that James wanted to show [the friend] something," police allege. "[James] stated that the police came to his property to look for Carver's remains," the inmate allegedly told authorities. Police say the cellmate knew James Larson personally, as the cellmate was engaged to marry his wife Penny Larson before being locked up, per the affidavit. Penny Larson was taken into custody last week in Missouri and charged with first-degree murder, while James Larson was charged behind bars.
