I was able to speak to the original developer who pointed me to the Esri legacy samples which provided the syntax for what I was trying to do.
var symbol = new esri.symbol.SimpleMarkerSymbol(esri.symbol.SimpleMarkerSymbol.STYLE_SQUARE, 10,
new esri.symbol.SimpleLineSymbol(esri.symbol.SimpleLineSymbol.STYLE_SOLID,
new dojo.Color([255,0,0]), 1),
new dojo.Color([0,255,0,0.25]));
App.map.graphics.add(new esri.Graphic(queryResults[0].feature.geometry, symbol));
App.vent.trigger('Search:ShowIdentifyResult', [queryResults.features[0]]);
