The teeth were intact, and there did not appear to be signs of a strong blow to her face or head, he said.
In addition, Steger’s left index finger was cleanly broken between the knuckle and the lower finger joint. “The fracture is complete,” McGee said, adding that it likely occurred during a struggle.
A woman with Trevino’s family cried audibly early in McGee’s testimony and walked out. Marcie Steger left after Assistant Ramsey County Attorney Richard Dusterhoft asked McGee whether Steger could have been smothered with a pillow.
“Yes,” McGee said.
Steger’s grandfather, Norman Kelch, found a bloody pillow and pillow case, sports bra, T-shirt and bath sponge in a plastic bag at Keller Lake on March 16.
McKenzie Anderson, a DNA scientist with the Minnesota Bureau of Criminal Apprehension (BCA), testified Wednesday that several spots of suspected blood from the couple’s master bedroom, home and inside Steger’s car trunk matched Steger’s DNA.
Steger was a “single-source” DNA contributor for several pieces of evidence, including stains from the master bedroom, carpet fibers from the bristles of a carpet cleaner, a smudge under the bedroom doorknob and the pillow case, Anderson said.
Anderson said Steger’s DNA was found on a box spring in the bedroom that had about 150 small spots of suspected blood spatter.
Steven Swenson, a BCA scientist and blood spatter expert, testified that those stains likely came from a source that was located lower than the top of the box spring.
Attorneys clashed at the end of the day over transcripts that prosecutors had prepared of two police interviews with Trevino.
Dusterhoft gave copies to Conard on Wednesday morning, but Conard said he should’ve received them sooner. Dusterhoft said that he received copies from county secretaries about a month ago and that they are only on hand to refresh the memory of a retired St. Paul police sergeant who is supposed to testify.
The audio recordings of the interviews and the transcripts will not be admitted in court as evidence, Dusterhoft said.
District Judge Leonardo Castro asked both sides to review the audio and transcripts Thursday morning.
Testimony will resume at 1 p.m. Thursday with Conard’s cross-examination of Anderson.
