20-year-old Ellyzabeth Rainey was sentenced Friday to 41 years in prison for the brutal murder of her mother-in law.
Rainey pleaded guilty to the second-degree murder of 59-year-old Deborah Rainey, according to ABC. The defendant killed her mother-in-law in April 2013 by pouring boiling water on her, throwing weights at her, stabbing her to death and then pouring bleach into her mouth and nose.
The gruesome scene took place in the family’s Colorado Springs apartment, where she lived with her husband Jason Rainey and their newborn baby.
According to a police affidavit, the couple was on the brink of a divorce. The husband’s mother had come from San Francisco about two weeks prior to help take care of the infant.
Investigators also noted that Ellyzabeth Rainey and her mother-in-law had a troubled relationship.
"Ms Rainey commented that Deborah has never liked her anyway … she got tired of being pushed around so 'she killed her,'" Det. Shawn Peterson said in the affidavit.
Furthermore, Ellyzabeth Rainey informed investigators that she had been diagnosed as bipolar at 10 years old but did not take any medication. She said she heard voices telling her that Deborah Rainey would “take everything away from her,” according to ABC. The young wife and mother had been hospitalized for “hallucinating.”
Rainey’s lawyers did not claim insanity on behalf of their defendant.
Police responded to a noise complaint from a neighbor, finding the baby crying and a bloody butcher knife on the kitchen counter. Rainey picked up her child and asked the officers to take it, responding "because I just killed someone” when asked why. She then threw the baby at one and fled. While one officer caught Rainey, another found the body under an air mattress.
According to the Colorado Springs Gazette, Rainey planned the slaying well in advance, buying and hiding a set of knives in the laundry room and planting her husband’s free weights in the living room.
