Demi Moore’s Twitter account part of suicide help

CASSELBERRY, Fla. -- Actresses Demi Moore and Nia Vardalos were linked to an online chain of Twitter posts that ultimately led to Florida authorities intervening Friday when an 18-year-old man threatened to commit suicide.

Moore's Twitter account, mrskutcher, was among those responding to a message from a young man threatening to hang himself in his front yard in Casselberry, north of Orlando. Moore - with more than 2.5 million followers - and husband Ashton Kutcher are both active on the social network.
