An official autopsy report provides more clues about what led four to women being killed, execution style, in south Tulsa in January.
The report confirms twin sisters, Rebeika Powell, 23, and Kayetie Melchor, 23, were each shot twice in the head and their friend Misty Nunley,33, and neighbor Julie Jackson, 55, were each shot once in the head.
However, the medical examiner also says drugs were involved.
"It's still tragic and still the only one that are responsible for it are the ones that killed them," said Tulsa Police Homicide Sergeant Dave Walker.
Autopsy results show each of the victims had meth in their systems, the least amount in Jackson and the most in Rebeika Powell.
Her mother has been waiting to hear the truth of what happened that day, but the examiner’s finding of meth is especially painful.
"I am not going to admit this; I want you to know that right now,” said Charon Powell.
Arrest reports show one of the accused gunmen, James Poore, told detectives he knew Rebeika Powell and sold and dealt drugs with her. He and his brother Cedric Poore are accused of going to the apartment to steal her meth and killing the four women inside the apartment.
"There is no ‘why’ someone had the right to go in there no matter what they were doing, no matter what was in their system. No one had the right to put bullets in their heads, especially to four women,” says Charon Powell.
The autopsy report shows Rebeika Powell, Misty Nunley and Julie Jackson were tied up with blue bedding and that Kayetie Melchor was tied up with a pink scarf. Police say Melchor’s body was found in a different room.
"It could just be that they weren't prepared and she walked in and they had to use something different but that is speculation,” said Walker.
However, the fact is that their families have been left to grieve and ask why.
"Why would someone need to shoot someone twice in the head? It's just, it's cruel, it's awful and it’s terrible,” said Charon Powell.
Court records show the Poore brothers both have criminal histories and were released from prison early.
The witnesses in the case are not listed in online jail records but FOX23 News has been told they are in custody.
A preliminary hearing is scheduled for April 2nd, that’s when a judge will decide if there’s enough evidence for them to go to trial. FOX23 News has been told the defense has asked for a continuance and the judge will make a decision on Tuesday.
Both have pleaded not guilty to first degree murder charges.
