UPDATE: A Tennessee judge says a toddler who witnessed her mother's death will not have to testify in her father's murder trial.

The Knoxville News Sentinel reports Knox County Criminal Court Judge Steve Sword ruled the child would not have to testify about the 2015 death of her mother. Jury selection is scheduled to begin Monday in the trial of the child's father, who is accused of killing his ex-wife and kidnapping their daughter and fleeing to Ohio.

Prosecutors wanted to use tapes of an interview with the then 2-year-old girl as evidence. They said they would need the now 4-year-old girl to introduce the tapes from the witness stand.

Sword listened to the interview and ruled the girl was unable to describe a "coherent historical recitation" of what she saw.

Tests showed blood found on the girl, who was 2 years old at the time, belonged to her mother, Assistant District Attorney Kevin Allen said.

Allen said he plans to show that the girl witnessed her mother's murder and has memories of her father's involvement. 

Tyler Enix is accused of stabbing his ex-wife, Kimberly McFarland Enix, 47 times in her Fountain City condo in October 2015, then kidnapping their daughter, Brooklynne Emerie. The case triggered an Amber Alert -- first in Tennessee and then in surrounding states -- and less than 24 hours later, an alert driver in Ohio spotted Enix's vehicle.
