"It was approximately 11 by 8 inches, so about the size of a sheet of paper," said Elizabeth Schwab, a criminalist with the Arizona Department of Public Safety.
It's about a foot long, that stain, along with another tested positive for human blood according to a DNA analyst.
"Both of those reacted with antibodies for human blood, indicating human blood was present," said DPS Criminalist Erin Higgins.
The other stains were too small to test. The jury also saw pictures of Hunter's neighbor's car, and the dumpster in Tempe where police believe Hunter threw Jhessye Shockley's body away. Spots were found on the trunk, and they tested positive for blood.
The handler of a second cadaver dog also testified.
"She smelled decomposition in the trunk," said Barbara Sampson, an MCSO Canine handler.
Her dog found the scent of decomposition on the same three pieces of evidence as the first cadaver dog did. The neighbor's trunk, the carpet, and the dumpster.
"She was sure she had found what we were looking for, she hit it very strong," said Sampson.
The trial is set to resume Monday.
