Moriarty, N.M. ? FBI agents have arrested a man authorities want to question in the disappearance of a Moriarty teenager.

Kevin Jensen, 42, was arrested at a relative’s home Friday in Overland Park, Kan., said Jeff Lanza, an FBI spokesman in Kansas City.

Jensen probably will be taken before a federal magistrate today in Kansas City, Kan., Lanza said.

Torrance County Sheriff Pete Golden has said Jensen was not a suspect in Robert Stroup’s disappearance but that deputies wanted to talk to him.

“All we want to know is where Robby is right now so we don’t have to hunt and search and worry,” his mother, Bea Stroup, said in an interview with KOAT-TV.

Jensen is charged in Torrance County with child abuse and contributing to the delinquency of a minor for allegedly giving liquor to boys at his home, Golden said.

Investigators used dogs and a helicopter Sunday to search an area where human remains, including a head, were found north of a missing teenager’s home.

State police spokesman Lt. Rob Shilling said there were a total of eight more finds Sunday. He would not elaborate on what was found other than to say it included additional remains.

“The remains were consistent with the skull found yesterday,” Shilling said.

Additional personnel were summoned to assist with the search today, he said. The search, which started Sunday morning in southern Santa Fe County, included dogs trained in sniffing out cadavers, Shilling said.

The remains were taken to the Office of the Medical Investigator in Albuquerque, but whether they were those of missing 15-year-old Robert Stroup probably could not be determined until today at the earliest.

Stroup was last seen the night of Oct. 27 when he reportedly went to a haunted house in Albuquerque with Jensen and another teenager. Jensen has told authorities Stroup had eaten dinner at his home and left on foot about 10 p.m. that night.

Bea Stroup reported the boy missing Monday afternoon. She has said it is not like her son to run away and that she fears he has been abducted and killed.

Authorities have searched an area about 10 miles in diameter around the Stroup home in a working class neighborhood on the edge of Torrance County farm country north of Interstate 40.

They found a sweatshirt and one shoe they believe are the boy’s at a water tank near his home last Monday.

Robert, a Moriarty High School freshman, is described as 5-foot-11 and 130 pounds, with blue eyes. His mother said he’d sprayed his hair blue for the trip to the Albuquerque haunted house with Jensen.
