The teen accused of stabbing her sister and mother to death is now facing capital murder charges.

The teen accused of stabbing her sister and mother to death is now facing capital murder charges, but it's still not clear if she will be tried as an adult.

Rosa Lee Maldonado, 19, and her mother Rosa Aminta Maldonado, 44, who both used to live in Albion, were found dead inside their home in Limestone County, Alabama last Wednesday.

Deputies say Rosa Lee's 15-year-old sister stabbed them then stabbed herself in the neck and head with a butcher knife.

She was released from the hospital on Friday and formally charged with two counts of capital murder.

Her name is not being released because of her age.

Authorities say it could take a few months before courts determine if the suspect will be charged as an adult. Federal law bans anyone convicted in capital crimes committed when they were younger than the age of 18 from getting the death penalty.
