"Tweets" sound so cute and innocent, but it turns out they can do some real damage. The case against a young man in Harlem, accused of killing a childhood friend on Jan. 3 may rely heavily on short, angry posts exchanged between the two. "N-----s is lookin for u don't think I won't give up ya address for a price betta chill asap!" wrote the suspected murderer, just hours before the fatal shooting. According to the Daily News, lawyers will now try to prove that there was bad blood between the former schoolmates by citing their aggressive Tweets.

We've heard about Facebook bullying and Twitter being used by NY gangs, but this will be the first time the 140-word or less posts are brought as evidence in a murder trial. The victim, 22-year-old Kwame Dancy, was shot in front of 45 W. 132nd Street, across from the Lenox Terrace apartments, according to the NY Post. The killer on trial is an old friend of Dancy's, James Blake, who'd filled his Twitter page with little threats. For instance: "R.I.P. Kwame," posted on December 3rd.

Possibly attempting to establish a cover, Blake also showed up at the hospital after the shooting and hugged Dancy's bereaved father. Besides their Twitter-beef, the two had fought previously, and publicly, over a woman. The victim's mother was shocked to learn that the long-time pal fired the shot that killed her son. "They were good friends, that's the sad part about it," she said. "Obviously, I didn't know him like I thought I did. I just want to ask him. 'Why? How could you?'
