Ecuadorian migrant who strangled her baby and dumped him in trash is RELEASED from prison following 12-year stint and immediately transferred to ICE custody: 'The heinousness of her crime cannot be overstated'

An Ecuadorian woman who served 12 years in prison after admitting to strangling her newborn baby and dumping him in the trash has been released and transferred to immigration detention. 

Maria Oliva Guaman, 33, was living in New York state as an undocumented migrant when she strangled her days-old son and throwing his body in a recycling container outside a store in Spring Valley in 2013.

Her sentence, after pleading guilty to manslaughter, included five years of post-release supervision and deportation.

Immigration and Customs Enforcement (ICE) said Guaman was released on Friday and immediately arrested by Enforcement and Removal Operations (ERO) officers.

'The absolute heinous nature of the crime cannot be overstated as this woman strangled her newborn baby to death and tossed him in a dumpster,' said ERO New York City Field Office Director Kenneth Genalo.

Guaman entered the US illegally sometime before January, 2009, when she was deported to Ecuador.

However, she made her way back to the country illegally again at some point after that deportation.

She was arrested in December, 2013, months after the murder, after DNA tests linked her to the newborn baby.

His body was found inside a plastic bag amid discarded cardboard, with his umbilical cord hanging, at a recycling plant in Westchester County.

Guaman's son was called the 'Baby Angel' by police and the press while detectives worked to locate his mother. 

During her trial, two psychiatrists testified that Guaman had an IQ of only 53 after having suffered brain damage when she was kicked in the head by a horse when she was seven years old.

The independent experts both testified Guaman was suffering an extreme emotional disturbance when she killed her baby. 

Guaman also has a daughter, and her family described her as a good mother at the time of her arrest.

They said they had no idea why she had committed the heinous crime.
