ST. PETERSBURG — A Chicago property management firm is buying the troubled Citrus Grove Apartments at 731 15th St. S, City Council Member Karl Nurse announced during a Wednesday news conference. Nurse wouldn't name the firm because he said the deal hasn't been completed. But he said the firm has agreed to contribute about $1.5-million for renovations of the complex, which was home to Nicholas Lindsey, the 16-year-old arrested earlier this year and charged with the murder of police officer David S. Crawford; and was the hangout of three young men charged in the 2009 murder of 8-year-old Paris Whitehead-Hamilton. Nurse cheered the pending sale, which he said he helped facilitate. The sale should be complete by the end of the year, and renovations of the 84 units are set to begin by March, he said.
