A serial rapist who terrorized women on Boston's Esplanade for years before his 2015 arrest pleaded guilty to the attacks Friday.



Alejandro Done, 49, faced multiple rape and kidnapping charges for attacks on three women in 2006, 2007, and 2010. The case was expected to go to trial next month, but Done changed his plea at a status conference, according to a news release from Suffolk County District Attorney Daniel Conley's office.



Conley praised prosecutors and police for decades of work on the case, which he said hopes will bring "satisfaction" to Done's victims.



"The defendant's admission of guilt is the direct result of countless hours spent in pursuit of a predator, first to identify him and then to build an ironclad case against him," Conley wrote in the news release. "The victims in this case, and all survivors of sexual assault, can take some satisfaction knowing that he's finally been held accountable."

Done became connected to the attacks on the Charles River Esplanade and in South Boston

after DNA evidence obtained in a 2014 attack, for which is serving time in state prison, matched other victims.

Done picked up a woman who mistook him for her Uber driver on Tremont Street in December 2014. When the woman was in the car, he told her she would need to pay with cash and drove her to an ATM, prosecutors said at the time.

The woman returned to the car with money and Done drove to a secluded area. He parked, jumped into the backseat of the car and hit the woman. He strangled her and locked the doors while covering her mouth so she couldn't scream, prosecutors said. Done was sentenced to 10 to 12 years in prison for that crime.

He is scheduled for sentencing in the Esplanade attacks July 18.
