An area some distance up the hill — across from a pull-off parking area — was marked with 14 yellow flags in photographs.
Wright said the yellow markers indicated where police found blood on the pavement.
He said police also collected a T-shirt that belonged to Taylor from the apartment he was sharing with Samantha LaCroix, Rennie’s on-again, off-again girlfriend.
And they collected a pair of Calvin Klein jeans from the master bedroom of Rivers’s mobile home on Grove Street in Keeseville.
“They were on the floor,” Wright said, “and appeared to have stains on them consistent with blood stains.”
LaDuke asked Wright in cross-examination whether police secured the scene before walking toward Rennie’s body.
Wright said they had.
Then LaDuke showed the investigator a photograph police had taken of a boot print in the sand.
Sprague later asked Wright if he recognized the photograph.
“Is that the other side of the bridge,” she asked, “and there was an (police) officer stationed there?”
“Yes,” Wright said.
LaDuke also provided the court and the jury a photograph showing a gash found on the back of Rennie’s head.
A second police officer, Trever Giroux, testified that he had taken the photographs, including the one of the boot print.
“The reason I took this is there is a footprint in it,” he said. “It was going away from … the River Street side (of the bridge).”
At this point in testimony, Assistant District Attorney Michael Langey showed the court sneakers worn by Rivers and boots worn by Taylor and Denno.
Giroux said he collected the footwear from Rivers and Taylor when the men were being questioned by police on Aug. 26.
The boots worn by Denno were collected at a later date, Giroux said.
