DENVER -- A 29-year-old woman who was arrested last week for allegedly abandoning her newborn in a trash can at a Cherry Creek sports bar partied at another bar shortly after giving birth to the infant, according to an arrest warrant affidavit released Tuesday.

Erin Pendleton was arrested on Friday for investigation of child abuse resulting in death, Denver police said Tuesday.

A cleaning crew found the full-term baby boy June 25 inside a women's restroom trash can at Legends Sport Bar in North Cherry Creek. Pendleton is currently being held in the Denver County Jail.

Friends who were with Pendleton told police that she left their table for about 90 minutes and was later found in the women's rest room clutching a vest around her waist. She told her friends that she has passed a kidney stone and was bleeding.

After they left the bar, the friends told police that the three of them went to another bar and continued drinking.

The baby's corpse was found in a trash can in the women's restroom short after the bar closed for the night. The umbilical cord was still attached to the infant and the placenta was also present, according to the arrest warrant affidavit.

Detectives were able to locate Pendleton by tracing a credit card receipt used in the bar after a waiter described a woman "layered in clothing and acting ill."

The Denver coroner said the infant was a male and was born alive. The cause of death is listed as asphyxiation.

Pendleton was hiding in a an apartment crawl space when detectives arrested her, 7NEWS reported. The district attorney has until Thursday to file charges against her.

The discovery of the newborn came a day after a baby boy was found in a Dumpster. The child was revived and placed on life support equipment at a hospital, but later died.

In that case, 20-year-old Griselle Suarez faces charges of first-degree murder and child abuse resulting in death. Suarez is being held without bond.

Court documents show her family suspected she was pregnant but she had denied it.

Suarez told police she didn't want anyone to know she was expecting so when she had the baby in the family's bathroom, she hid it and was planning to take it to the hospital after she cleaned herself up.

A state law allows parents to abandon healthy newborn babies within 72 hours at hospitals, police or fire stations.
