The release of a man imprisoned for setting his 6-year-old son afire has been delayed again, officials said. The new release date for Charles Rothenberg, 48, is Feb. 11, 1990. Rothenberg initially was to be released from the California Men's Colony here Dec. 11, then it was delayed until Jan. 9. The state twice added about a month to Rothenberg's jail time for circumventing mail room procedures. Parole authorities are searching for a community in which Rothenberg can be released. Residents of Desert Center voted against allowing Rothenberg to work at the state's minimum-security prison at Eagle Mountain. Rothenberg's son, David, now 13, was burned over 90% of his body.
