NASHVILLE, Tenn. (AP) -- A message sent on the social networking site Twitter could be linked to a shooting at a Nashville park where hundreds had gathered for an outdoor movie.

Police said a 15-year-old was wounded in his left knee on Wednesday after he flashed gang signs at the Centennial Park just after the movie ended. No one has been arrested. The Movies in the Park is a popular weekly event during the summer.

The Tennessean reported part of a tweet sent on Tuesday said, "Someone will die tomorrow at MITP."

Lt. Gordon Howey, head of the Metro Police Gang Unit, said this was the first time they've heard of Twitter being used like that in a crime.
