Had to be drugs.
Whatever ... he pissed SOMEbody off.
Sounds likely ... from the article;
Camacho has a career record of 79-5-3, with his most recent fight coming in 2009.
Drug and alcohol problems have trailed Camacho since the prime of his boxing career.
He was sentenced in 2007 to seven years in prison for the burglary of a computer store in Mississippi. During the arrest in January 2005, police found him in possession of ecstasy.
A judge eventually suspended all but one year of the sentence and gave Camacho probation. He wound up serving two weeks in jail after violating his probation.
He divorced from his wife several years ago after she filed multiple domestic abuse complaints against him.
From this, it would appear that he would have been safer in prison. Then again, boxing is not conducive to long-term brain power. Something about repetitive concussions.
