CORTLAND COUNTY, N.Y. -- The crime scene photos prove it was a cold, brutal act that ended the life of nurse Janet Pottorff, 53, last July. But whether or not her husband, Keith Pottorff, was her murderer is now the argument in Cortland County Court.

On Thursday, the State Police investigator who photographed Pottorff's body in a shed near her home took the stand for the prosecution. He described the evidence he found after he went to the couple's property on Dog Hollow Road in Truxton.

The jury saw photos of Janet Pottorff lying in the corner of the shed, her wrists and ankles bound behind her back, a cord around her neck and plastic bags taped over her head.

But the defense questioned whether the evidence pointed to Keith Pottorff as the murderer. He was picked up at the Grass Roots music festival in Trumansburg while police searched for his wife.

The defense argued a burglar wearing gloves could have come onto the property and not left any fingerprints. It was a speculation the investigator said he couldn't make.

The prosecution also called a fraud investigator to the stand, who said a check for $975 made out to Keith Pottorff was cashed from Janet Pottorff's personal account the day she disappeared.

Pottorff admitted to police he has had problems with drugs, but denied any involvement in the killing.

The prosecution will continue to call witnesses Friday. Pottorff faces 25 years to life in prison if he's convicted of his wife's murder.
