State Police investigators are exploring a possible link between a North Carolina trucker suspected in a series of slayings along interstate highways and the serial killings on and around the Colonial Parkway.

Virginia investigators have been in close contact with authorities in North Carolina and Tennessee since they learned of Sean P. Goble's arrest in Winston-Salem on Thursday, Assistant Special Agent Bill Littreal said Monday.

Investigators in Virginia haven't interviewed Goble about the so-called parkway murders that claimed eight young men and women between October 1986 and September 1989. But ``we are definitely interested in him to see if he was in the area during that period of time,'' Littreal said. Littreal is assigned to the Bureau of Criminal Investigations' violent crimes section.

Goble, 28, of Asheboro, N.C., has confessed to killing three women on different occasions. A first-degree murder charge is pending against Goble in the slaying of a 45-year-old Indiana woman at a truck stop in Greene County, Tenn. Goble told authorities he strangled her and dumped her body along Interstate 81 in Washington County, Va., which borders North Carolina and Tennessee. The body was recovered Jan. 23.

Goble has also confessed to the slaying of a 36-year-old Ohio woman, who was suffocated at another Tennessee gas station near I-81, authorities said. Her body was discovered March 19 about 60 miles away, near the highway in Kingsport, Tenn.

On Monday, authorities said that Goble will be charged with murdering the unidentified woman whose body was found Feb. 19 off Interstate 40 in Guilford County, N.C.

In Virginia's parkway killings, the bodies of two of the suspected victims, Keith Call and Cassandra Hailey, have never been found. Call's car was found abandoned on the Colonial Parkway the morning after the couple had a date in April 1988.

``At this time we have nothing to tie him to the serial killings on the Colonial Parkway and the rest stop along I-64 in New Kent,'' Littreal said.

Over the past decade, the bodies of dozens of women have turned up along interstates in nine states. Unsolved killings in Ohio, Florida, Kentucky, Georgia, North Carolina, Tennessee, Virginia, Missouri and Indiana fit the pattern of those to which Goble has confessed, authorities say.

Authorities impounded Goble's black 1988 Peterbilt tractor-trailer rig and reportedly found bloodstains in the cab.

Investigators reportedly found pornographic magazines and movies and women's undergarments and women's shoes during a search of Goble's mobile home. And a pocketbook belonging to one of the slain women was found in his truck.

Although Goble hasn't been eliminated as a suspect, Littreal acknowledged that there are profound differences in the parkway murders and the slayings along the interstate highways.

``The MOs are entirely different,'' Littreal said.

He said many of the victims in the interstate highway slayings were women who were picked up at truck stops and several were prostitutes.

Investigators often compare notes with other police departments when they have a homicide that might fit the pattern of a serial.

The FBI is charged with investigating the slayings along the parkway because the road is on federal government property.

Goble waived extradition and is expected to be turned over to Tennessee authorities on Wednesday.
