SPOKANE, Wash. -

A day after the arrest of a murder suspect in Doug Carlile's killing, the FBI has raided the home of one of Carlile's business associates in North Dakota as detectives continue working to determine whether he was the victim of a hostile takeover.

The FBI confirmed its agents raided the home of James Henrikson in Watford City, ND Wednesday. There's no information yet as to what the FBI was looking for when it raided Henrikson's residence.

Murder suspect Tim Suchow was arrested by Spokane police early Tuesday morning and booked into the Spokane County Jail on a single count of pre-meditated first degree murder.

It's likely Suchow never met Carlile before he allegedly shot the 63-year-old Spokane man inside his home. Police say he was the hit man in a long distance business deal gone bad.

"The victim, Mr. Carlile, was involved in a series of complex business transactions centered on oil fields in North Dakota," Spokane Police Chief Frank Straub said. "Evidence suggests that those transactions may have provided motive for the homicide."

Detectives discovered Carlile, one of four owners in Kingdom Dynamics Enterprises, was trying to buy Henrikson out of his share of 640 acres of North Dakota land they owned mineral rights with plans to drill for oil.

Those attempts to buy Henrikson out were rebuffed, while Henrikson, according to court documents, allegedly attempted to buy Carlile out in order to attract an investor who refused to put money into Kingdom Dynamics Enterprises as long as Carlile was involved.

"We believe that it is very possible that the homicide was the result of those business transactions that went bad," Straub said.

The tensions between the two were so high, a witness told detectives someone has been practicing writing Carlile's signature inside Henrikson's home and confirmed he overheard Henrikson threatening to kill Carlile and his family.

Henrikson, however, told detectives he never threatened his business partner and is not responsible for his murder.

"We can certainly bring charges here in the State of Washington if we can prove that there's a linkage between North Dakota and here," Straub said.

That proof could come if Suchow deals with detectives and tells them who allegedly hired him to kill Carlile.
