LA CROSSE, Wis. (WEAU) -- A year ago Wednesday, Todd Kendhammer was arrested in connection with the death of his wife, Barbara Kendhammer.
He initially told deputies she was killed by a pipe that fell off a truck and went through their windshield while they were driving and struck her.
Wednesday, during day three of the trial in La Crosse, the state called more witnesses, including two who Kendhammer says were involved in a job he claims he was on his way to at the time of the incident.
Other witnesses included an investigator at the time with the sheriff's department and former co-workers of Barbara.
Medical Examiner Dr. Kathleen McCubbin, who performed the autopsy, was also on the stand for more than two hours, testifying about her report.
"The cause of Barbara Kendhammer's death were blunt impact injuries to her head and neck," said Dr. McCubbin.
Dr. McCubbin testified she discovered Barbara suffered a fracture around her trachea, which suggests there was strangulation or a strike to the neck.
She also concluded that a single impact from a pipe, with or without subsequent breaking and possible whiplash type injury, could not account for the multitude of injuries Barbara showed
Testimony is scheduled to resume Thursday morning around 8:30 a.m.
