A Michigan woman who won a $1 million lottery prize didn't know about it for months, after leaving the ticket in a pile of mail.

Lottery officials say Linda Tuttle of Kentwood stepped forward Tuesday with a winning ticket from the May 26 Mega Millions drawing.

Tuttle told officials she recently found the ticket at home among some old mail. She didn't search until a clerk at a local store mentioned that it had sold a $1 million winner in May.

Tuttle plans to use some money to visit former exchange students in China.
