Hours before she was shot to death at a large block party near Moncks Corner early Saturday, 19-year-old Ariel Morgan tweeted that she hoped criminals would stay away so she and her friends could enjoy themselves.

Morgan had also retweeted - or shared - this tweet from a friend: "I really wanna show face at the block party, but I don't wanna lose my life man."

Since the shooting, which also injured four others, family and friends have expressed sadness and anger on Twitter and Facebook.

Some people also told stories of their struggle about whether to let their children attend the block party, which was intended to celebrate graduating high school students.

There were also lots of tweets and Facebook posts in the moments immediately after the shooting.

But most of the posts have been disbelief that a smiling young woman is gone so soon.
