BOISE, ID -- Testimony continued in the Duncan trial on Tuesday with more evidence of Duncan's behavior prior to the murders and a video of Shasta Groene.

The morning after being rescued, Shasta did an on-camera interview with the Kootenai County Sheriff's Office. Jurors watched that interview in Boise's federal court.

In the interview she told authorities Duncan molested her and her brother and videotaped those events.

"If you guys got a hold of that tape you'd be crying really hard," she told investigators.

Roughly a week into their kidnapping, Groene said she believed Duncan accidentally shot her brother with a 12-gauge sawed off shotgun. She described seeing her wounded brother before Duncan shot him one more time.

In the interview Groene quoted Duncan as saying: "Oh my God, oh my God!" She said he was sad and crying.

She then helped Duncan by wrapping Dylan's body in a tarp. The boy's remains were burned on a campfire.

Earlier in the day, a witness in the Joseph Duncan death penalty trial told the courtroom he made contact with Duncan on May 5, 2005 near the U.S./Canadian border.

Bryan Olson was spraying weeds when he briefly saw Duncan near a gravel pit near Stryker, Mont.

Duncan saw Olson and asked him why he was at work on a weekend day. Olson replied to Duncan and told him it was Monday.

Olson told the courtroom that Duncan acknowledged that he had his days mixed up and appeared disoriented at the time.

Earlier in the morning session federal prosecutors continued their presentation of GPS coordinates taken from Duncan's vehicle as they tracked his whereabouts after he kidnapped Dylan and Shasta Groene.

Other evidence presented by prosecutors showed that Duncan was camping and collecting children's toys throughout the region.

A jury previously convicted Duncan for the murder of Dylan Groene.
