Police say a woman was walking her dog in the Fox Run Park in Bear, Delaware on Wednesday when she noticed a black Adidas bag that she thought looked suspicious.
On Thursday she saw the bag again and decided to look inside.
That's when she saw the missing jerseys.
She took the bag to state police, who then returned it to the school.
Those jerseys went missing back on September 18th when someone stole the bag from a vehicle at the Red Lion Christian Academy.
The person who stole the bag has not yet been identified.
