A man who lives in a north Edmonton bungalow described Thursday how he found a baby's body in a rented bedroom in the basement.

Homicide detectives began investigating Wednesday afternoon after they were called to the home near 69th Street and 130th Avenue.

"I went downstairs to change over the laundry, and my dog was going nuts at one of the bedroom doors," said Wayne, who lives upstairs in the home with his family and asked that his last name not be used.

"I opened the door. My dog ran to the right side of the bed. I went over and looked, and there was a white bag and I pulled the bag out and noticed there was red through the bag."

The man said he called his girlfriend, who opened the bag and found the dead baby.

The woman who lived in the basement was in her 20s and went to school with his girlfriend, Wayne said.

"People thought she was pregnant but she denied it. It's a sad situation."

An autopsy was completed Thursday, but results have not been released as police continue their investigation, said police spokeswoman Patrycia Chalupczynska.

Chalupczynska also said the infant was a girl, although police earlier identified it as a boy.

No other details are being released.
