MIAMI, Florida (CNN) -- Police think it started with a dispute over an ex-girlfriend. Threats were made on social networking sites and via text messages. The suspects, clockwise from top left are: Lernio Colin, Angel Cruz, Peter MacDonald and Christopher Harter. A murder plot was hatched and, police say, in the early hours of last Saturday morning, a Florida man was gunned down in his car. But the suspects apparently killed  the wrong man. Now four men are in custody, and will face charges of first degree premeditated murder and two counts of attempted murder. The four are Angel Cruz, 23; his brother from Oregon, Christopher Harter, 29; Peter MacDonald, 18; and Lernio Colin, 20. They have all appeared before a judge in Fort Lauderdale, Florida.
