A Calgary judge has released a key piece of evidence in the trial of a mother accused of throwing two of her newborn babies in dumpsters.

The videotaped confession of 32-year-old Meredith Borowiec — who faces two counts of second-degree murder in connection with the deaths of her infants — shows her in a police interrogation room for 11 hours, answering questions from Calgary police.

Despite Borowiec's lawyers arguments against the video's release, Justice Peter McIntyre has now allowed media access to the footage.

"I was horrified with myself," Borowiec told police in her confession. 

In 2010, Borowiec was arrested and charged with attempted murder after a newborn baby was found alive in a dumpster outside her home.

A year after that arrest, Borowiec was interrogated about two other babies that she said she had given birth to in 2008 and 2009.

Their bodies have never been found.

Tossing babies an 'out of body' experience: Borowiec

​While answering questions from Det. Karla Malsam-Dudar of the Calgary Police Service, Borowiec said she had felt out of control and that she had been having an "out of body" experience each time she threw the babies in the garbage.

She said she had hidden each pregnancy from her longtime boyfriend and gave birth at home during the day.

Each time, Borowiec says she wrapped the baby in a towel, placed it in a garbage bag and took it out to a dumpster.

"Did you put the babies in the same spot each time?" asked Malsam-Dudar.

"No," said Borowiec.

"Where did you put the second baby?" said Malsam-Dudar.

"In the further dumpster," said Borowiec.

Earlier this week, a court-appointed psychiatrist told the judge that Borowiec was not suffering from any mental illness at the times of the births.

Her trial has been running on and off since March and final arguments are set for next Friday.

If convicted of second-degree murder, Borowiec will face an automatic life sentence with no chance of parole for at least 10 years.
