(NewsNation) — Former University of Kentucky cheerleader Laken Snelling claims she fell asleep on top of her newborn baby after giving birth, according to new court documents.

The new court documents, obtained by NewsNation affiliate WDKY, state that Snelling told police she was awake for about 30 minutes after giving birth and then fell alseep on top of the baby, and when she woke up after passing out, she saw the infant “turning blue and purple.” She believed the baby had died, telling police she wrapped him “like a burrito” to lie next to him because “it gave her comfort.”

Police responded Aug. 27 to Snelling’s off-campus apartment, where they found the baby boy’s body in a trash bag. He was reportedly cold to the touch. Investigators determined the infant had been dead for three to four hours.

Snelling, 21, was arrested Aug. 31 and charged with abuse of a corpse, tampering with physical evidence and concealing the birth of an infant.

Snelling ‘guessed’ baby was alive: Affidavit

According to the affidavit, Snelling told the UK student health center staff she “guessed” her baby was alive, reporting he showed “a little fetal movement” and a “whimper” at birth. She admitted to leaving the apartment briefly after delivery to pick up McDonald’s and visit the health clinic, where she “also did not go inside,” before returning home, according to the affidavit.

Messages authorities obtained from her roommates indicate they heard loud noises the night of the birth but were unaware of the pregnancy. Snelling told her roommates she fainted from not eating and was going to see a doctor, according to the documents. The roommate later investigated Snellings’ room and found the baby boy in the closet.

Search warrants of Snelling’s phone, Snapchat, Instagram, Facebook, and iCloud revealed deleted pregnancy searches, labor photos and evidence of a concealed pregnancy.

Snelling wasn’t home when an unknown individual placed a 911 call about a dead newborn found in a closet of her off-campus home. She admitted during questioning that she had given birth and put all the evidence in a trash bag, some of which she wrapped in a towel.

Judge rules Snelling case will go to grand jury

A preliminary autopsy could not determine the infant’s cause of death, and an investigation is ongoing to determine if it was born alive or stillborn or whether she could have suffered a miscarriage. Snelling pleaded not guilty to all charges on Sept. 2. She withdrew from the university and was placed on in-home incarceration at her parents’ home after posting a $100,000 bond.

On Friday, Snelling appeared in Fayette County District Court for a preliminary hearing, where a judge ruled there is sufficient evidence for the case to go to a grand jury for an indictment. A grand jury could add to or change the charges after hearing evidence and testimony.
