Siskiyou County Sheriff Jon Lopey reports that his office is tying up loose ends in three Siskiyou County cold cases and expects to soon put emphasis on those that have been on the back burner.

Siskiyou County Sheriff Jon Lopey reports that his office is tying up loose ends in three Siskiyou County cold cases and expects to soon put emphasis on those that have been on the back burner.

With the recent arrest of Arnold Aggas, Sr., Lopey is hoping the Kimberlie Kantonen case will soon be resolved.

He said “significant progress” is being made in the Karin Mero and Hannah Zaccaglini cold cases, and plans call for concentrating the Department’s efforts on the 2002 disappearance of Mount Shasta resident Angela Fullmer.

“The Fullmer case will be a priority as soon as we can free up some resources,” Lopey said Monday. “We want to keep all of these cases in the forefront of people’s minds, even second- or third-hand information can be valuable.”

Such information recently led to “promising leads” in the McCloud cold cases, Lopey said.

In February, the Sheriff’s Department submitted the Mero case to the District Attorney’s office for review of criminal charges stemming from her 1997 disappearance.

Lopey said evidence suggests the Zaccaglini and Mero cases could be connected, so progress made in one case may go toward solving the other.

The Kantonen case
Arnold Aggas, Sr. is charged with murdering 19 year old Kantonen, who was four months pregnant at the time of her disappearance in 1989.

At this time, Aggas is in custody at the Siskiyou County Jail with bail set at $750,000. He is also charged with several charges of rape by force/fear/etc.; several charges of sodomy with a person under 14 years old with force; a charge of rape of an unconscious victim and a charge of forcible oral copulation – all in a case unrelated to Kantonen’s.

The Siskiyou County Sheriff’s Department, with the help of a California Department of Justice Forensic Evidence Team are currently conducting an extensive search of Aggas’ Hornbrook property which encompasses about five acres, Lopey said.

Detectives are hopeful they may find Kantonenn during the careful search, Lopey said.

Last week, cadaver dog trainers from Tehama County and from Jackson County, Ore. led investigators to a potential site on a piece of ground at the back of the property and just up from the Klamath River, which borders the property to the east, said Captain Jim Betts.

Dive teams searched the river from the Aggas property line down to the Klamathon Bridge.

“We feel confident [with the evidence] but are still investigating and are hoping to find additional substantial evidence to aid in the pending case,” Lopey said.

Aggas’ next court date is on Aug. 9 at 8:30 a.m.

The Mero and Zaccaglini cases
“We’re still vigorously pursuing investigative leads in the Hannah Zaccaglini case,” Lopey said. “I think we are making some good progress, and coupled with the Mero case, we are confident we’re going to achieve more progress on that case. We have every reason to believe these women met with, and were victims of violent crime.”

Lopey said he believes an arrest is imminent in the Mero case, but it is dependent on a review by the DA or the Grand Jury.

Mero, 28, was last seen on Feb. 15, 1997, and 15 year old McCloud High School student Zaccaglini went missing four months later. Lopey said both women were seen at the same McCloud residence before they disappeared.

Siskiyou County DA Kirk Andrus said the Mero case is believed to be a homicide, but the victim’s remains have not been found.

“That significantly complicates our ability to prove the case, but I feel strongly that the case continues to progress,” Andrus said on Monday. “We will not forget Karin or the other victims in [these] cold cases. I met with Karin's parents several months before her father passed away and remain committed to bringing Karin’s killer to justice.”

The Fullmer case
Fullmer, 34, disappeared in the Twin Pines area near South Fork Road in December 2002. Authorities initially believed Fullmer had gotten lost in the forest and looked for her there, but inclement weather hampered search efforts.

Now Fullmer’s disappearance is considered suspicious, Lopey said, and he hopes to discover what happened to her nearly 10 years ago.

“The case of Angela Fullmer is on our radar screen, and we’re looking into some leads in that case,” he said.

At the time of her disappearance, Fullmer was the mother of five daughters ranging in age from 7 to 17. Shortly before she went missing, Fullmer had purchased and wrapped Christmas gifts, and asked her mother to take care of her children if something was to happen to her.
