TULSA, Okla. -- Frustration is growing for the family members of four women shot and killed two years ago.
After several delays, brothers James and Cedric Poore are set to stand trial for the murders, but the victims' families are concerned about how the case is being handled.
Charon Powell, whose twin daughters died, said she is particularly concerned about withheld evidence and a judge's decision to deny testing even more.
"All day long," Powell said, "it's pretty much all you can about just because you want justice for your children. These were my babies."
Her daughters, Rebeika Powell and Kayetie Powell Melchor, were shot and killed along with Julie Jackson and Misty Nunley at the Fairmont Terrace Apartments in midtown Tulsa in January 2013.
From the beginning, Powell claims all the families felt frustrated with the handling of the murder investigation.
"There was just a lot of things that we feel that weren't investigated that should have been investigated," she said, "or was not given to the detective and even if it was given to the detective, where was it put after that?"
Their concerns grew in October when a judge postponed the started of the jury trial for one of the suspects, James Poore. Prosecutors found out Tulsa police unintentionally failed to share some of their records, though the district attorney said those records should not affect the charges facing James and his brother Cedric.
Powell, however, still wonders if the records could contain clues about other suspects.
"We believe that there's more people involved," Powell said. "I'm not saying that the Poore brothers are innocent, just that there's more people involved."
Another status hearing for the brothers will be held in January 2016.
