The state medical examiner who conducted the autopsy on the body of Mollie Tibbetts testified this afternoon in the trial of Cristhian Rivera, who is accused of killing her.
Medical Examiner Dennis Klein says Tibbetts’ body had deteriorated in the July heat — but he was able to find nine stab wounds — and there were possibly 12 overall wounds to her body. Defense attorney, Chad Frese, asked if Klein determined one knife was used.
“They would all be consistent with one weapon — but I am not able to exclude more than one weapon,” Klein responded. Frese asked about how the wounds occurred. “Could you tell the vantage point of the assailant from where the wounds were located,” Frese asked. Klein said “no.” “So you couldn’t tell if the assailant was in standing front of or behind miss Tibbetts?,” Frese asked. “That’s correct.”
Klein said he could also not say if the killer was standing over Tibbetts. Investigators say Rivera killed Tibbetts after following the University of Iowa student while she ran in her hometown of Brooklyn, and then put her in his trunk before taking the body to a cornfield. Frese asked what other information Klein found from the autopsy.
“Can you tell anything from these wounds the size of the assailant?,” Frese asked. Klein said “no”. Frese also asked if the attack on Tibbetts appeared to be frenzied, and Klein said he could not determine that from the wounds — he could only tell the location and number of wounds. Frese also asked about wounds to Tibbett’s neck that would have severed arteries and veins.
“Those all if they’re severed cause significant blood loss don’t they?,” Frese asked. “Yes,” Klein answered. “And you’d expect to find significant blood in a location other and in a cornfield — if say that blood was say in the trunk of a car,?” Frese asked. “Correct,” Klein responded.
Investigators had said they found a small amount of blood in the trunk the Rivera’s car which matched Tibetts’ blood. The prosecutor followed up with Klein — and asked him if blood from the killing could have been on the ground and deteriorated.
“I think after rain and decomposition, it could be not be visibly apparent to the eye,” Klein says. The prosecution rested their case, and the judge denied a motion by the defense to dismiss the case.
The trial will resume at 8:30 a.m. Tuesday.
