Retired state trooper Richard Matas testified that bloody footprints were found on the carpeting of the trailer after police did a test that shows blood not visible to the eye. However, they were discounted because a number of investigators had been in the Pulaski Township trailer just after the murders. He said there were 16 people inside the trailer June 15, 1994.
Matas also revealed under questioning that police found only the Dryfuse family's fingerprints inside the trailer and no others. Nothing was taken from the trailer, and it didn't appear to have been ransacked, he added.
DNA expert Beth Ann Giles said she found the DNA only of Bonnie Lou Dryfuse on the woman's wedding ring. The ring was discovered near the doorway of a laundry room in the trailer.
Other DNA, including blood found on Heather Dryfuse's arm, could not be identified because it was consistent with more than one person, she said.
State Trooper Daniel Keith Johnson, a crime scene investigator, said he inspected Thomas Dryfuse's hands the day of the slayings and found no fresh wounds or bleeding. He did see a dark substance under nails, but it didn't appear to be blood, he said.
