My sister had her toddler's birthday party on the weekend and at the party an envelope containing $100 was dropped outside in the garden.
The money was to be a gift for my nephew from my parents.
Upon realising the envelope was dropped in the garden my mother went out to look for it. She asked some children (age around 8-12) whether they saw the envelope and they said their dad picked it up. He jumped in quickly to claim it had only been a lolly wrapper.
My sister asked that individual's daughter (age 5) whether she had seen the envelope in the garden and she said her dad picked it up and put it in his pocket. He denied it and said it had been a lolly wrapper.
So my question is should my sister have approached that individual about the money or left it and done nothing?
There is no proof this person pocketed the money apart from his kids all saying he picked up the envelope.
