Killers' confessions of crime on social media a growing trend
Florida man who posted photo of wife's corpse is among many to share details of crimes online

Derek Medina's was not the first Facebook confession, but it may have been the most graphic.
At least a handful of others have posted online about killing someone, but this seems to be the first time anyone included a grisly photo of the corpse. Medina, 31, made the post on Thursday after allegedly killing his wife, then turned himself in to police.
In December 2011, a middle-aged Indiana man posted that he had shot dead his 19-year-old ex-girlfriend and her friend. He also announced his own death.
"someone call 911. three dead bodies at 3229 lima road fort wayne Indiana," he wrote. "I've killed ryann, erin, and myself. People were warned not to play me and ruin me. They didn't listen. Sorry about your luck."
