The family declined comment.
In addition to admitting to the murder of her baby, Avila-Villa pleaded guilty to gross abuse of a corpse, tampering with evidence and unlawful sexual conduct with a minor.
According to the facts of the case, Avila-Villa killed the child and threw his body in the trash behind her Shuler Avenue residence to cover up the crime.
Prosecutors have said she killed her baby to escape punishment for having sex with the underage male who fathered the child.
By taking the plea, Avila-Villa gave up the right to appeal her case.
Butler County Prosecutor Michael Gmoser said Avila-Villa’s mental health issues before, during and after her child’s death likely would be sufficient mitigation for her to avoid the death penalty at trial or in future appeals.
He said Avila-Villa admitted to her crimes, which he called “horrific.”
“The complete admission of guilty across the board, coupled with her documented mental health issues, made this the right thing to do,” Gmoser said.
Defense attorney Melynda Cook said she is “happy we were able to get this done for her.”
Co-Counsel Chris Pagan could not be reached for comment.
