COEUR D'ALENE, Idaho — A memorial service for Dylan Groene, whose remains were found in western Montana seven weeks after he was abducted from his home near here, is scheduled for tomorrow, the day he would have turned 10, his relatives say.

The boy and his sister Shasta, 8, were abducted on May 16 after three members of the household were bludgeoned to death.

Shasta was recognized by customers and staff at a Denny's restaurant here on July 2 and the man with her was arrested.

That man, Joseph Edward Duncan III, 42, a registered sex offender, has been charged with three counts of murder and three counts of kidnapping in the deaths at the family's rural home.

Duncan has been held without bail since his arrest.

The Fargo, N.D., resident was released on $15,000 bail earlier this year after being charged with molesting a 6-year-old boy in Minnesota. Police in Fargo had been looking for Duncan since May, when he failed to check in with a probation agent.

The Pacific Northwest Inlander, a free weekly based in Spokane, reported yesterday that law enforcement officers recovered a video camcorder from Duncan's vehicle that contained footage of him abusing and threatening to kill the two children during their captivity in western Montana.

The newspaper cited unidentified sources "working various aspects of the case" for the information. The FBI, U.S. Attorney's office in Boise and Kootenai County prosecutor and sheriff's offices all declined to comment on the report Thursday. Sheriff Rocky Watson said previously he believes the motive for the attack on the family was to acquire the two young children for sex.

Public defender John Adams said he has not yet received any information from law enforcement officers on what was found in the Jeep, and is upset by rumors involving his client.

"The vast majority of people want trial by rule of law in courtrooms," Adams said, not "trial by press and anonymous sources."

In Idaho, Duncan faces three counts of first-degree murder and three counts of first-degree kidnapping in the slayings of Brenda Groene, 40, her 13-year-old son Slade and her 37-year-old boyfriend Mark McKenzie. Federal prosecutors have said they will bring federal kidnapping and murder charges against him in the abduction of Shasta and Dylan Groene, and the slaying of Dylan.

On Wednesday, Steve Groene, father of the children, asked a judge to allow 18-year-old Jesse Groene out of jail to attend tomorrow's memorial service. First District Judge John Mitchell granted the request.

Jesse Groene is serving a six-month sentence for burglary, and is in the Shoshone County Jail in Wallace awaiting transport to a state prison.

Dylan Groene's remains were found at a primitive campsite in Montana's Lolo National Forest on July 4. Information from Shasta led authorities to the scene.

Authorities have released no details about how Dylan was killed, and have refused to confirm media reports that his remains were found burned.
