Her husband, Jeffrey Trevino, is charged with second-degree murder in her death. His lawyers originally requested a May 15 deadline for all scientific evidence to be disclosed.
Kira Trevino's body was pulled from the Mississippi River on May 8, and results of an autopsy have prompted prosecutors to prepare further evidence in connection to Jeffrey Trevino's alleged attempt to conceal the murder.
The autopsy indicated Kira's body had sustained numerous injuries, including a head wound, broken finger, bruising inside her upper lip, and lacerations to her liver.
Prosecutors suggest an attempted cover-up following the discovery of her body in the river due to evidence of her blood in the trunk of her car, in the carpet cleaner in her home and rearranged furniture in the bedroom.
DNA testing should take an additional four weeks, the motion indicates, and a medical examiner's complete autopsy will take six weeks. Prosecutors request a new deadline be granted at the May 15 pretrial hearing.
