The Texas Court of Criminal Appeals on Wednesday ruled that Routier should be allowed to conduct DNA testing on blood stains, flakes of dried blood and hairs found at the crime scene.

Routier's previously appeals to the court had been denied, but state law allows for post-conviction DNA testing in some cases. Routier has maintained that she is innocent of the murders.

Routier was accused in the slayings of the young boys, Damon and Devon, but was only tried and convicted in the death of Damon. She has maintained that an intruder at the family's home killed them.
