Norwich, NY (WBNG Binghamton) Testimony Thursday revolved around evidence collected in the murder case against Peter Wlasiuk in Chenango County.
Wlasiuk is accused of killing his wife Patricia in 2002.
Once again burdock was discussed throughout Thursday's testimony.
A forensic expert with the New York State Crime Lab was asked to open bag after bag of evidence containing clothing and other items he examined in 2002.
He told jurors he found burdock on both Patricia and Peter's clothing.
Evidence of burdock is important to the prosecution claim that Peter smothered Patricia and killed her in the burdock bush outside of their home in Oxford.
The forensic expert testified that a test for blood came back positive on Peter's sweatshirt and on Patricia's sweater.
Jurors heard from another member of the state crime lab who said hair found on a burdock bush at the Wlasiuk's home matched Patricia Wlasiuk's DNA.
The same match was there for hair found in the bed of the couple's truck, which had gone into Guilford lake where Patricia's body was recovered.
During the cross examination of Chenango County Sheriff Ernest Cutting, the prosecution raised multiple objections to questions.
It involved both sides taking time to talk with Judge Joseph Cawley to resolve issues.
The trial continues Monday morning.
The Prosecution is still presenting its case.
Thursday was day 10 of testimony in Wlasiuk's re-trial.
