Crime-scene evidence shown in court on second day of Paape trial

SHEBOYGAN (WITI) -- Officials described a gruesome murder and a horrific murder scene, as Nathan Paape's murder trial continued on Tuesday, June 18th.

Paape is one of two boys who were just 13 when they are accused of killing 78-year-old Barbara Olson -- the great-grandmother of the second suspect, Antonio Barbeau.

In court on Tuesday, jurors had to view graphic autopsy photos and hear about the extent of injuries Olson suffered in this crime.

Hard evidence linked to the September 2012 crime was taken out of bags and boxes, including clothes prosecutors say the 13-year-olds wore, quarters they are accused of stealing, products they tried to clean up with after the crime -- and the murder weapons: a hammer and a hatchet.

The Medical Examiner described what he discovered when he examined the victim.

"In examining the head, I found there were at least 18 different injuries or blows. 11 of these have evidence of sharp force and most of them have evidence of blunt force," Douglas Kelley said.

Prosecutors say Paape and Barbeau took Olson's car, jewelry and purse after she was killed.

Two days after the murder, Kenneth Smith, an agent with the Department of Justice interviewed Paape about the crime. Smith had a piece of paper in which he says Paape wrote: "He killed his grandma and I was with him."

Barbeau has pleaded no contest to first-degree intentional homicide as part of a plea deal.

With the plea deal, Barbeau changed his plea from not guilty by mental disease or defect to no contest. Barbeau will be eligible for parole in 35 years.

Barbeau is set to testify in Paape's trial on Wednesday, June 19th.
