A Danbury woman accused of killing her newborn son in 2018 by leaving him in a dumpster admitted to disposing of another baby boy about a year later, according to a new search warrant.

On June 18, Dominique Harrison, 28, was charged with murder with special circumstances, the most serious homicide charge in the state, in a nearly eight-year-old case. The baby’s body was discovered at City Carting, a trash and recycling center in Stamford, on Oct. 16, 2018.

When Harrison was arraigned on that charge on June 22, investigators were already working on building another murder case against her for a second newborn, per a search warrant obtained by News 12.

The search warrant said Harrison gave another interview to police right after her arrest regarding a second pregnancy. She said a visit to Planned Parenthood in September 2019 confirmed she was pregnant, then in November, gave birth to the baby at home one night while her family was asleep. Harrison initially told police she dropped the baby at Danbury Hospital under the Safe Havens Act, per the search warrant, but when confronted with the fact there was no record, Harrison admitted to wrapping the newborn in a white “Snoopy” blanket and putting him in the woods behind her home.

"The baby was alive when she placed him in the wooded area because it was crying,” the search warrant said, but when Harrison returned the next morning at 8:30 a.m., "She knew it was dead because it was not breathing and was a little blue."

Harrison took the baby out of the original blanket, wrapped him in a different one and put him in a recycling dumpster near the front of the home, something she never told anyone about, according to the search warrant. She kept that Snoopy blanket in a plastic bin in the basement, and though she washed it, "believes that there might be a small amount of blood on it," per the search warrant. The document said investigators seized the blanket from Harrison's home after her arrest and sent it to the state forensic lab for testing.

During Harrison’s arraignment at Danbury Superior Court last month, Assistant State’s Attorney Mary-Caitlin Harding said more “very serious charges” are expected, seeming to allude to the allegations in the search warrant.

“Your Honor, the case before you paints a picture of a level of depravity that is nearly inconceivable,” Harding told the judge on June 18, regarding the current charge. “The defendant here is charged with murdering her newborn son in a manner that is particularly heinous. The facts allege she put that newborn baby son alive in a dumpster in a remote area, so that no one could save that baby's life.”

Harrison’s arrest warrant, which was initially sealed, details the lengthy investigation that ultimately led police to arrest her nearly eight years later after the discovery of the dead newborn.

She's being held on a $2.5 million bond and is due to make her second court appearance on June 24.
