Girl’s teddy bear with recording of late mom’s heartbeat mistakenly donated to thrift shop

Four-year-old's father dropped off the stuffed bear at a Tennessee Goodwill, after which it was quickly sold

A heartbroken four-year-old girl's lost teddy bear, containing a recording of her late mother's heartbeat, has sparked a desperate search in Tennessee after it was mistakenly donated to a thrift shop.

The tie-dyed bear was dropped off by the girl's father among other donations at the Goodwill Industries store in New Tazewell about 50 miles (80km) north-west of Knoxville, company officials say, and was quickly sold.
