Dog Found Dead In Oven: Grisly Discovery For Chicago-Area Family Returning From Vacation

An Arlington Heights, Ill. family made a gruesome discovery after returning from vacation: Coco, their family dog, dead inside an oven.

The Daily Herald reports that the family alerted police after they came home to what appeared to be a burglary last week in the 1500 block of West Roanoke Drive. Their dog, a Cavachon, was also missing.

The dog was found by the family's 9-year-old girl in a convection oven, the Chicago Sun-Times reports. About $3,000 worth of jewelry was also taken from the ransacked home.

“It’s terrible for someone to do something like that to a poor, defenseless animal,” a neighbor of the family, a single mother with two daughters, told the Sun-Times. “She was definitely devastated.”

Police have not said whether the dog died before or after it was put in the oven, the Chicago Tribune reports.

Police have determined that the break-in was a domestic case and have identified an ex-boyfriend out on bond from a previous domestic charge as a person of interest in the crime, CBS Chicago reports. He has not been charged in the incident as of Saturday morning.
