Wanted: Walter Alvarez

Do any of you know a Miami resident (or former Miami resident) named Walter Alvarez? He would be about 43 years old nowadays. In 1983 he was interviewed for an article in the Miami Herald. His mother’s name is/was Adelaida. I’d like to chat with him as sort of a follow up to the Herald article 25 years later.
If you know him, give him my email address: conductor@babalublog.com.
