Lexis Walker

She left a note, took a bag and left.

Now investigators are using helicopters, search dogs and multiple fire departments to search for 15-year-old Lexis Walker in the area of her Locust Lane home.

She was last seen by her twin brother, Levi, between 7 and 8:30 Monday night. She was playing a game of horseshoes by herself. She went into the woods after losing a horseshoe. She tried to locate the horseshoe with one of her dad's tools and lost the tool.

This upset her and she left, family said.

She was last seen wearing a peach and orange zip-up hooded sweatshirt and black yoga pants. She is about 100 pounds, she has two different colored eyes and a scar above her right eyebrow.
