Alejandro Done, 46, of the South End, will face charges for at least six rapes and sexual assaults dating to 2006 - but investigators say they are looking at his connection to additional attacks.
Done was indicted recently for allegedly raping an Uber passenger in Cambridge after picking her up on Dec. 6 on Tremont Street in Boston.
A judge ordered him to supply a DNA sample. Suffolk County District Attorney Dan Conley said today that State Police criminalists got a match for that from samples from four of five attacks on the Esplanade, Moakley Park and Preble Circle.
Conley called him a violent sexual predator who went after women walking alone late at night on summer weekends.
Conley said Done does not appear to have a prior criminal record.
In addition to the Cambridge rape, authorities have linked him to attacks on July 29, 2006 in Moakley Park, June 16, 2007 on the Esplanade, July 29, 2007 on the Esplanade, July 13, 2009 on the Esplanade and July 13, 2010 near Preble Circle.
At a press conference on the Esplanade today, authorities did not release Done's photo, but said they might after he is arraigned on the Boston charges, possibly tomorrow.
