Rexford Keel Jr. was arrested during a traffic jam at Interstate 10, near Tucson, Arizona. The sheriff's office in Nash County, North Carolina, issued a first-degree murder order for the 57-year-old last week.
Kill made no statements to the police. There were several Wales Fargo receipts and a large sum of it, the sheriff's office said. Diana Kill, 38, was reported missing on March 9 and was found dead three days later about 30 miles from her home. Rexford Keel was the last person to see her alive, the police said.
The police interrogated Rexford Kyle on Tuesday and released him without charge, said Major Mister Strickland from the Nash County Sheriff's office. After an autopsy on Wednesday, the police said Diana Kill's death was treated as a murder. Later, they said they did not know where her husband had gone, and had been looking for his 1998 pickup truck.
Investigators take a second look at the death of Kiel's first wife, Elizabeth Edward Kyle, who died in 2006 in the same home where Keel lives, said the sheriff's office.
At that time an accident was made by the doctor, the sheriff's office said. The autopsy shows that she died after falling and hitting her forehead at the corner of the concrete steps at the front of the house.
Strickland told CNN that the detectives are working with the FBI and other local agencies to investigate the deaths of both women.
