An Arkansas woman arrested after an officer was stabbed to death this week has been charged with murder, authorities say.
Emanuelle Rushing, 24, is accused of stabbing the officer and a man to death in retaliation for a stabbing earlier this month.
She has been charged with two counts of capital murder and one count of first-degree murder, according to the Arkansas State Police.
Her bond was set at $1m.
It comes after Rushing was arrested on suspicion of killing the officer on Monday.
Lieutenant Mitch Cato, the investigating officer in the case, says the investigation now focuses on a separate double murder of two men.

The body of Richard Lee Cantrell, 58, was found on Tuesday at a petrol station and a woman was found injured in the car nearby. The woman was identified as Gayle Rushing, Ranting’s sister.
On Wednesday, Gayle Rushing, 60, died from her injuries.
Lieutenant Cato says the case involves a “homicide involving multiple stab wounds”.
It is also “involving a motive and an element of revenge”, he said.

Police did not release any details as to why Gayle Rushing was wounded.
Rushing was arrested on Monday on suspicion of killing the officer, who was found with multiple stab wounds at a home in Clinton, Arkansas.
“We have a lot of evidence that ties her to this crime,” Detective Sgt Dan Turner told reporters on Wednesday.
No motive has been released in relation to the officer’s death.
“You’re seeing the resolution of this case,” Mayor Terry Ellis said after Gayle Rushing’s death was announced.
“[Rushing] was a hero in this case.”

The officer, Clinton police officer Antwain “Tony” Bynum, was stabbed twice in the stomach by Rushing while responding to a call, police said.
“I want to thank the Fayetteville Police Department, Lewisville Police Department, Arkansas State Police and the entire Clinton community for the overwhelming support,” his family said in a statement.
