Daughter Anna (right) with her friend and alleged accomplice, Rachel Facebook

An Illinois teen who police claim killed her deaf mother before setting her house on fire wrote a goodbye message on her Facebook page saying she had been her “best friend”.

Anna Schroeder, 15, allegedly lay in wait with a 0.38 revolver for her mother Peggy to get home from work in Morrison, Illinois, on Thursday.

Anna then asked Peggy, 53, to put a towel over her face, before shooting her to death in the head in the living room of the house the two shared, according to the Sauk Valley local newspaper.

The girl then texted her friend Rachel Helm, 15, about the alleged crime and sent her a picture of the body.

Detective David Molina, the sheriff who interviewed both girls, testified that the two tried to clean blood out of the carpet and moved Peggy’s body to her bedroom floor, covering her with a bedsheet.

The next day they bought more cleaning products for the carpet, and dyed their hair in preparation to run away.

On Saturday they set the house on fire to destroy the evidence, walked to a nearby cemetery and hid Anna’s phone and gun.
