Nantucket woman who killed her three-year-old daughter because she thought her child was possessed by the devil has been found not criminally responsible due to her mental illness.  Dora Tejada, 28, was found not guilty by a judge today in Nantucket Superior Court. Instead, she had been committed to a state mental health institution for six months of treatment and observation.

Tejada told police that Nicole Garcia, the child allegedly killed, died because God commanded her to shove a rose down her three-year-old daughter's throat in order to rid her of demons. Tejada told authorities the Holy Spirit can speak through her. They were called to the house in March 2011 after Tejada suffocated her daughter with a rose and found Nicole lying dead on a table inside it.

Examiners and psychiatrists made the verdict that her bipolar disorder and psychosis left her unable to understand her actions

According to Tejada, God told her to push a rose in her daughter's throat in order to exorcise the devil.  Examiners noted that Tejada also pushed her fist down the girl's throat.

The cause of death was homicidal asphyxia.

Three forensic psychologists--  hired independently by the defense, by the prosecution,  and by the court-all came to the conclusion that the severity of Tejada's  psychosis and bipolar disorder meant that she was unable to understand what she was doing and totally unable to conform her behavior to the law on the day her daughter died.

"Usually, with a lack of criminal responsibility, you don't get three experts that agree," James Caramanica, Tejada's attorney, said outside the courtroom court after the verdict.''But this case was so clear to everyone involved."

Prosecutors didn't challenge the judge's decision.

Assistant District Attorney Sharon Thibeault said, "All the evidence - the testimony, the physical evidence, everything - it all supported the experts' finding in this case."

During the three-day trial, friends and relatives described Tejada as a loving responsible mom who suddenly became more religious about a week before the killing when she attended a religious retreat.

Tejada also had had a traumatic childhood in El Salvador and suffered from chronic depression for a decade, a psychologist said in his testimony.

Tejada originally told police that she'd fallen from the sofa in her Nantucket house while she was asleep with Nicole. She said she woke up to other people asking if anyone had injured her child.

 While being questioned, she sang and prayed. When left alone in an interview room, she assumed a crucifiction pose for several minutes.

But she was taken to hospital after investigators saw skin hanging from of her hand.

Court records say that Pleitez told officials while she was being treated God had told her to stick a rose down her daughter's throat to rid her of demons, so she did.

Later, she told her pastor that the rose was actually her fist and that the devil bit her hand through Nicole.

Roses and rose petals were found on the floor of the home. Her son may have also been in danger. Through a translator, Tejada eventually said that she "thought about fighting the demons out of both children" and that at one point she "had a child in each arm".
