HAMMOND, Ind. (CBS) — Police in Hammond, Ind., might know who is responsible for human bones that were found last week in the remains of a demolished building.

As WBBM Newsradio’s Nancy Harty reports, Hammond police Chief Brian Miller says detectives have a person of interest in mind in connection to the bones found by a dog at the Great Lakes Bait and tackle building, at 1718 Indianapolis Blvd., which was demolished last week.

“Looking at the business, looking at the building, trying to find people that have knowledge of that building and, you know, hung around that building,” Miller said.

Miller says investigators found the rest of the remains about 20 feet from the original dig site. The bones are believed to be that of a woman, and may date back 5 to 10 years.

Miller says the additional bones have been sent to a forensic anthropologist from the University of Indianapolis.

The bones were discovered last week, when a 2-year-old Rottweiler named Brutus began digging around a demolition site in the back.

The dog, who belonged to the owners of the cell phone store next door, had been sniffing the lot for a couple of days.

“I noticed he had something in his mouth. It turned out to be hand with a ring on the finger,” said A-1 Wireless store owner Mike Bender. “After that, I went back in to the yard, asked him to dig around a little bit more, and at that point he found a skull.”

While there has been no suggestion yet of whom the bones might belong to, one woman, Delores Starnes, told CBS 2’s Kristyn Hartman she believes the bones might be those of her 42-year-old daughter, Doreen Fogle, who disappeared 15 years ago.
