I have already emailed the information. Lopez competed in the 1998 or 99 (can't remember) Golden Gloves national championships in Biloxi, MS, and lost in his first bout. He had no prior or future national experience. Was not a "national level" or elite boxer.
There is a Nelson Lopez -heavyweight- that has fought amateur out of Pahokee, Florida. His father ran -or maybe still runs- a small group of amateurs and an ocassional prelim pro out of that area.
