(Radio Iowa) – The state medical examiner who conducted the autopsy on the body of Mollie Tibetts testified this (Monday) afternoon in the trial of Cristhian Rivera, who is accused of killing her. Medical Examiner Dennis Klein says Tibetts’ 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.

Frese asked about how the wounds occurred.

Klein said he could also not say if the killer was standing over Tibetts. Investigators say Rivera killed Tibetts after following her 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.

Frese also asked if the attack on Tibetts 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 Tibett’s neck that would have severed arteries and veins.

Investigators had said they found a small amount of blood in the trunk of 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.

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.
