TULSA, Oklahoma - Tulsa Police Department homicide detectives say a woman is in custody connected to a Tulsa murder in July. Leanna Marie Roacher is in the Tulsa County jail on a murder complaint, accused of helping with a deadly robbery. 

TPD's lead homicide detective says Roacher admitted to helping with a robbery that ended with a man being shot inside his apartment. Police say someone killed Michael Binder at the Cascades Apartments at Southern Hills July 27.

Officers say they interviewed Roacher Monday night with the help of Sapulpa police. 

According to an arrest report, Roacher admitted that she knocked on the victim's door and was let in. She told officers that her two accomplices then made entry into the apartment and demanded that both she and Binder get on the floor.

Instead, police said Binder called out for help and started to run for the front door. That's when one of Roacher's accomplices shot Binder in the head, the arresting officer said.

Detectives say the case is still under investigation and future arrests are likely.
