Melissa Arquero said she and her husband had been at a wedding Friday night; Briere was there too. Michael Arquero almost never danced, his wife said, but that night he made an exception and danced with the bride, a close friend. The couple already had a babysitter, and Briere said she prodded Mike to take his wife out for a fancy late-night dinner, but with her pregnancy cravings, the pair had been talking about getting tacos all day, Melissa Arquero said. So Arquero dropped her off at home, then drove down California Avenue to the small restaurant at Division and Maplewood.
