A woman faked an entire pregnancy for nine months, convinced her husband and family she was expecting a baby, then walked out of the hospital with a newborn hidden inside a gift bag.
The bizarre true-crime story of Alejandra Marín Mendoza is now the subject of Netflix’s new documentary A Child of My Own, landing on Thursday (13 August).
Directed by Oscar-nominated filmmaker Maite Alberdi, the film explores the extraordinary lengths Alejandra went to in order to become a mother, and the disturbing moment her elaborate lie turned into a real-life crime.

Alejandra had sadly already suffered three miscarriages and, according to the doc, faced intense pressure from her husband Arturo and his family to have a child.
She then began building an entirely fictional pregnancy around herself, gaining weight by eating more food, attending pregnancy yoga classes, faking ultrasound scans and even throwing herself a baby shower, all while maintaining the illusion that she was carrying her husband's baby.

And somehow, the deception became so convincing that Alejandra appeared to start believing it herself.
Alberdi says she wasn't simply putting on an act for the people around her. She genuinely wanted to live the pregnancy she had imagined, with the filmmaker describing her state of mind as resembling a psychological pregnancy.
"If you see the archive footage, it’s not a fat woman, it’s a pregnant woman," she explained via the Guardian. "So it’s like she did have a psychological pregnancy. She wanted to believe, and at some point, she was living that lie."

The story takes an even darker turn when Alejandra, who worked in hospital administration, met a pregnant woman named Mayra.
Alejandra claimed Mayra had agreed to give her the baby, but Mayra's testimony and court evidence disputed that version of events.
Alejandra ultimately posed as a social worker, took Mayra's newborn from the maternity ward and left the hospital with the baby concealed in a gift bag, with CCTV capturing her walking out of the building before she was arrested at a hotel hours later.

The baby was returned to Mayra, while Alejandra was eventually sentenced to 13 years in prison for child kidnapping.
What makes A Child of My Own particularly strange is that it isn't really a traditional true-crime 'whodunnit' mystery.
We know relatively early what Alejandra did, but the bigger mystery is what she believed herself, and how a lie sustained for months could become so psychologically real.
A Child of My Own is currently available to stream on Netflix.

Mendoza later claims to meet a pregnant woman called Mayra Navarro in the maternity clinic who didn’t want to keep her own baby. Mendoza claims she persuades her to carry the baby to term and give it to her.
According to local outlet El Siglo de Torreon, she says: "We talked during a consultation. She said she was a single mother, that it was her second child, by a different father, and that she wanted to terminate the pregnancy."
