(NEW YORK) -- Charlie Sheen has made a generous donation to a Florida teen who suffered serious injuries at an amusement park in Wisconsin three years ago.

Teagan Marti, who's now 15, fell 100 feet from a ride, causing brain, spinal and other injuries.

Sheen learned of her plight through a Wisconsin family who has been supportive of Marti's family following her accident and has raised money for her.  Last week, the actor donated $10,000 to Marti so she can get a therapy dog.

Marti is thrilled by Sheen's gesture, saying, "I just think it's really great and I want to thank him for helping us."
