CAMBRIDGE, Mass. (AP) — Construction workers putting support for a new deck at a Cambridge home dug up the concrete floor of a shed and found a skeleton buried there with a gun that appears about 100 years old.

Police spokesman Frank Pasquarello says an investigation the items found Thursday afternoon appear old and may be from a market on the property.

Forensic examinations are expected to reveal the age and gender of the skeletal remains found at the 149-year-old home on Cambridge Street.

Homeowner Rosalie Foster says the discovery was “unbelievable at first, and then it gets a little shocky and then you go ‘Wow, I got a body!”‘

Foster says police said she may claim the antique gun later on because it was found in her property.
