A startling confession was captured on recently released footage, showing a New York woman calmly admitting to suffocating and burning her infant son in an Albany park almost 30 years ago, a report reveals.

DNA analysis of the infant’s remains traced the case back to Keri Mazzuca, 52, who faced questioning last year regarding the death of “Baby Moses.” The child was discovered in 1997, wrapped in a towel and burned beside a statue of Moses in Albany’s Washington Park, according to News10.

The same DNA technology that led Mazzuca to be identified has been employed to apprehend suspects like the alleged Gilgo Beach serial killer Rex Heuermann and the notorious Golden State Killer, Joseph James DeAngelo, as reported by the outlet.

After being shown a gruesome photo of the newborn’s charred remains, Mazzuca made an admission with seemingly casual indifference, footage released by the Albany County District Attorney’s Office showed.

“I did it,” Mazzuca calmly states to the officer, before attempting to justify her heinous act when she was in her mid-twenties.

“I got pregnant. I had the baby. I gave birth in my bathtub; the baby died. I didn’t know how to get rid of it,” she claimed to officers — still not appearing to break into any semblance of emotional response.

Mazzuca denied burning Baby Moses, claiming that the child had died in the bathtub during childbirth and that she placed the corpse in a bag and handed it to a “random person” at the park, video showed.

Detectives told Mazzuca that an autopsy found Baby Moses had not died of natural causes and her story was not adding up, News10 reported.

“I didn’t know what to do. I set the baby on fire,” Mazzuca admitted calmly, while adjusting the hem of her skirt. “It was dead.”

“I suffocated the child,” she said, claiming to officers that the child was not alive when she lit him on fire.

Mazzuca pleaded guilty to a manslaughter charge in February and was sentenced to 25 years in prison last month, News10 reported.

Baby Moses was found on Sept. 7, 1997, in a blue towel — burned to death near a box of wooden matches, according to the Doe Network.

The child has a headstone in Graceland Cemetery that reads, “Moses Washington. Citizen of Albany. Child of God.”
