The chilling case of Andreina Lknown as the ‘Willow Slayer’, has shocked. This week it was confirmed that not only did she kill and dismember her own mother in 2025, but she was involved in the death of her best friend Jennifer Banguera.
Banguera was missing in 2022. This week, the Police confirmed that a body found that year and that was unidentified corresponded to the missing young woman.
The clues led to confirmation that a dismembered body placed in a suitcase and found in 2022 in Sauces corresponded to Jennifer Banguera. The Police links to Andreina L in this crime. This implies that her best friend was murdered three years earlier.
Andreína L. is a woman who shows coldness and without the slightest sign of regret for the performance. At least that was clear from an assessment made by an expert who interviewed her in prison.
Last January, this newspaper spoke with the psychiatrist Juan Montenegro, an expert accredited by the Judiciary Council, who spoke with Andreína.
As part of the proceedings of the case, the psychiatrist Montenegro, who spent 33 years as head of the Legal Medicine Service, had to carry out the psychiatric medical evaluation to Andreína L. in the Guayaquil women’s detention center.
The specialist dedicated four and a half hours to interview the young woman. He produced a 16-page report on his analysis.
Montenegro described that he was very struck by the fact that the young woman wore combed and with her nails doneas if she had been prepared for the interview with the expert.
In her performance, he also noticed that she was calm, cold and without the slightest sign of regret for the action for which she is being investigated. The visit took place on October 30 of last year.
In the first hour and a half, Montenegro tried to get the young woman to collaborate and tell what happened. To do this, he started a dialogue so that she could gain confidence and tell the truth. But at first he wanted to divert the topic to another area.
He began to tell an unbelievable story. She said that her mother had indeed died, that she had found her dead, and that those who had murdered her were criminals, because she owed money.
Afterwards, he continued asking questions and made her realize that what was narrated was a ‘lie’ based on the evidence pointing to his guilt.
“That now, with technology, there was a lot of evidence that pointed out that she had killed her mother, such as videos, chatsthat she had done it herself. “She had put on her mother’s clothes to pretend or mislead that her mother was missing,” he told her.
After these confrontations, later in the interview, the doctor questioned her about her age and what she wanted in her life.
She, who is now 32 years old, told him that she wanted finish studies, start a business and be a businesswoman. He insisted to her that if she continued lying she would not succeed, since the evidence points to her being the culprit of the matricide.
After that, the young woman agreed to tell how the events had actually occurred, accepting her participation in the murder.
“He took it very Olympicthere was no sign or sign of regret, of saying ‘well, I regret it, it wasn’t on my mind… it was a moment of anger or confusion’; There was no such narrative,” Montenegro said.
In Andreína’s testimony, the expert stated that her home was functional and there had been an extramarital conflict that led to her parents’ divorce. Specifically, based on the story, the expert stated that the woman would have had ‘another person’.
Because of that episode, according to the doctor, the young woman would have had problems or harassment with your mother. After her parents separated, the young woman stayed living in Sauces 9, and her mother and father lived in other neighborhoods.
“She tells me that the mother assumed and blamed her for having spoken to this person’s father, which she denied, she said that the father found out through other means. From there the mother began to harass her,” the expert described.
Constantly, the mother went to the apartment where the young woman lived. However, according to the story presented by Montenegro, both would have had friction, confrontations and they would have asked him to leave that place that belonged to the victim.
Those episodes would have been like triggers for the girl to make the fatal decision.
On the day of the events, Andreína’s mother would have arrived at the home where her daughter lived, took sleeping pills and went to lie down on a piece of furniture, Montenegro explained.
Afterwards, the young woman would have taken the phone charger cablewrapped it around the neck and generated pressure for about five minutes until he realized that his mother was no longer breathing.
To prove that she was dead, the young woman put a piece of clothing in the mouth. Then, according to the story collected by Montenegro, she created a whole situation, telling her friends and authorities that she had not seen her and even used her clothes to mislead the investigations into her alleged disappearance.
In addition, the expert said that the young woman told him that she later inquired about how to disappear a corpse. At first he didn’t want to get rid of it out of fear and that’s how it occurred to him dismember it with an electric knife.
Given this, the young woman would have been in charge of separating the upper and lower limbs, and the put it in the washing machine.
Then he took a knife, opened the abdominal cavity, took out some organs to put them in a plastic sleeve, while the rest of the body was placed in a plastic tank, the expert explained.
During the investigations in Montenegro, she told him that she sought to buy grain salt to cover the parts placed in the container.
During a raid on the home where Andreína lived, the Martha’s remains, so the young woman was detained.
In his story, Dr. Montenegro stated that the same suspect accepted that she was the one who killed the mother, separated her body, and that He had no help from anyone else.. “She didn’t have the slightest regret for having done it, she told me that she didn’t feel bad for doing it, that she didn’t feel bad, that she already did it,” he explained.
After this interview, the expert determined that Andreína has a paranoid or antisocial personality disorder of personality.
“These people are those who make society and the environment suffer, but what they do they do with full consciousness and full willshe knows that what she did was defeating legal, social, family norms, etc., by having killed her mother,” explained Montenegro.
This version, Montenegro explained, is valuable in ruling out other versions that she had some severe mental disorderthat she did it without consciousness or will, or even that she may have been possessed.
Regarding versions that point to Andreína for the case of a colleague who felt discomfort after drinking a drink offered by the young woman, she asserted that she did have participation, but everything was for scare him. It happened in 2022.
“She did accept the friend thing, what she wanted to do was just scare him, she recognizes that he put something in her drink“explained the doctor, who also added that the young woman mentioned that she would have had a conflict with that partner.
When Montegro inquired about Jennifer Banguera, the young flatly denied some kind of participation. Police investigations and DNA tests allowed us to close the case and determine that Andreína was related to the disappearance of her friend.
Andreína is imprisoned in La Roca prison, where 61 dangerous inmates are held. She has a 40-year sentence for her mother’s crime. (YO)
