Following Wisconsin law enforcement officials' news conference on the Jayme Closs case, former LAPD detective Mark Fuhrman said it appears the suspect in the teen's disappearance made some "careful and calculated plans."

Closs, 13, vanished Oct. 15 after her parents -- James Closs, 56, and Denise Closs, 46, -- were gunned down inside their home in Barron County, located about 80 miles northeast of Minneapolis. Officials determined Closs was inside the home when her parents were murdered, but then the trail went cold.

Closs was found alive, but dirty and malnourished, in the small town of Gordon, Wisconsin by a woman walking her dog. The woman brought Closs to a nearby home, where the couple called 911. 

A 21-year-old man was arrested shortly after Closs was found, and police identified him Friday as Jake Thomas Patterson. He is being held on charges of murder for the killings of Closs' parents and kidnapping.

On "America's Newsroom" Friday, Fuhrman noted that authorities said they believe Closs was Patterson's "only target," and Patterson, who had no prior criminal record, "planned his actions and took many steps to hide his identity."

Fuhrman said it appears Patterson left no forensic evidence -- such as hair or a footprint -- at the crime scene.

"He had no criminal record. So even if he left DNA, he wouldn't be in a database. If he left fingerprints, they wouldn't be in a database," Fuhrman noted. "So I think they were presented with a very difficult case."

"It was a very well-planned crime," he added, noting that Patterson was only in the Closs residence for four minutes, according to authorities.

Fuhrman said that while Patterson has no criminal record, he believes he has committed other crimes or has a mental defect.

"There's some prior history here somewhere, and I'm sure they're working on that right now," Fuhrman said. "I just don't think he escalated to a double homicide and a kidnapping as his first crime."
