MILWAUKEE (AP) -- There's a 15-year-old Florida girl who didn't really know much about Charlie Sheen before this week -- but does now.

The actor wired $10,000 to Teagan Marti and her family on Thursday for a therapy dog to help in her rehabilitation from injuries sustained when she plummeted 100 feet from a Wisconsin amusement park ride in 2010.

"I think he's a very kind person for helping me and my family and very generous," Teagan Marti said by phone Thursday from her home in Parkland, Fla.

Teagan Marti suffered brain, spine, pelvis and internal injuries in July 2010 when nets and air bags that were supposed to catch riders were not raised on a free-fall ride at Extreme World in Wisconsin Dells.

She initially had no use of her arms or legs but through physical therapy is able to walk again with a walker.

Teagan Marti's mother, Julie Marti, said they are financially in trouble from the medical bills and her recent divorce. Their house is being foreclosed upon and insurance isn't covering physical therapy anymore, she said. She had no idea how they would pay for the English Golden Retriever puppy.

"I'm in such disbelief," Julie Marti said. "I was crying. ... What a guy."
