After lunch recess, Spencer called a certified forensics examiner from New Mexico to the stand.
Dr. Karen Griest said she reviewed the autopsy report written by El Paso County Medical Examiner Dr. Juan Contin.
Griest said she found problems with the report because it didn't specify all the injuries found on Jacqueline's body.
She said she measured the width of Castaneda's knuckles and said it was consistent with pattern bruising on the little girl's body. Perez's knuckles were also measured.
Prosecution asked about the rest of the bruises that were not in a pattern form on the little girl's body.
At that point, photos of Jacqueline's body were shown to the courtroom once again.
Dr. Griest said the rest of the bruising could have been caused by injury with an object.
She did agree with Dr. Contin's report that Jacqueline died due to physical abuse. It was a blow to the back of the abdomen that caused her death.
A prosecutor asked, "If she got medical attention at all, would she have survived?"
"The likelihood of her surviving would be poor," said Dr. Griest.
Dr. Griest was also questioned about her certification in Pediatric Forensic Pathology after she stated there is no board certification for that specialty, adding she trained for only a year during a fellowship.
Griest said she has conducted up to 1,000 autopsies in her career.
Wednesday and Thursday Perez's attorneys argued that she was a victim of an abusive relationship and lived in fear of her boyfriend, Castañeda.
In a rebuttal, the prosecution called a witness to counter some of the statements made earlier by the defense's wintess' who said Perez fit the profile of battered woman syndrome.
Stephanie Karr, Director for the Center Against Family Violence was called up to the stand. She also spent about 13 years with the Child Crisis Center.
She agreed with the defense's experts that abusive relationships are a cycle, but that's where the agreement ended.
Karr said has come in contact with many women trying to get out of a violent relationship.
"A large motivating factor to seek help is the violence impacting their children. A majority of women who come into our center display protectiveness towards their children," said Karr.
Perez's attorney, Spencer, asked Karr if she had ever come into contact with his client.
She answered no and said she had no prior knowledge of the case. Spencer also pointed out that Karr was not a doctor or psychiatrist in family violence.
After both sides rested, Spencer asked the judge to drop the capital murder charge -- the judge declined.
Closing arguments are expected to begin Friday morning.
