Either Pittsburgh police or Allegheny County sheriff's deputies will travel to West Virginia to bring back the medical researcher charged with killing his wife with cyanide.
Robert Ferrante, 64, of Oakland intends to waive his extradition hearing on Monday, his attorney, William Difenderfer, said Friday.
A timetable for Mr. Ferrante's return had not been set Friday.
Mr. Ferrante was arrested Thursday night on Interstate 77 near Beckley, W.Va., after prosecutors sent out a national alert to be on the lookout for Mr. Ferrante, who faces one count of homicide in the death of his wife, Autumn Klein in April.
"My guy is adamant that he was not involved," Mr. Difenderfer said.
Yet, neither was surprised that police filed the charges. In the weeks that followed his wife's death, Mr. Ferrante began planning his estate, so that the couple's 6-year-old daughter, Cianna, could be provided for in case he was arrested, his attorney said.
Mr. Ferrante visited his adult daughter in California and then traveled to Florida, establishing residency there so that Cianna could enroll in a reputable school near Mr. Ferrante's sister in St. Augustine Fla., where he had hoped she would live if he was arrested. Mr. Ferrante chose the location in part because he wanted his daughter "sheltered and away from mayhem," Mr. Difenderfer said.
After the charges were filed, custody was awarded to Klein's parents.
Mr. Difenderfer said he will now begin focusing on analyzing the affidavit filed by Pittsburgh police and will rely on a team of experts that includes toxicologists, pathologists and others with knowledge of cyanide, as well as some character witnesses for Mr. Ferrante.
He said he will try to get bail for his client -- who is currently being held without bond in the Southern Regional Jail in Beaver, W.Va.
Investigators said they obtained a warrant Wednesday charging Mr. Ferrante in connection with the death of his wife, who was the head of women's neurology at UPMC.
Klein, 41, suddenly collapsed inside the couple's home April 17 and died in UPMC Presbyterian three days later.
According to an arrest affidavit, paramedics spotted a plastic bag containing a white substance -- which Mr. Ferrante told them was creatine -- and a vial sitting in the kitchen when they arrived to treat Klein.
Creatine, which typically comes in powder or pill form, is a dietary supplement most commonly used by bodybuilders.
One unnamed witness told detectives that two days before his wife collapsed, Mr. Ferrante asked to purchase the "best and purest cyanide he could get" and have it shipped overnight, according to the affidavit. Another said that cyanide did not pertain to his research.
Detectives quoted a friend of Klein as saying that Mr. Ferrante thought his wife was having an affair and she intended to leave him.
Hours before she collapsed, the couple exchanged text messages in which Mr. Ferrante tried to convince his wife to take creatine to stimulate her egg production. Klein's friends and family have said they believed she wanted to have another child.
Several people who have studied or worked with creatine said they have not heard of the substance being used to promote fertility.
Mr. Ferrante has been placed on unpaid leave at the Pitt medical school.
