A former Uber driver — who has already pleaded guilty to raping a woman in 2014 — shouted out one “not guilty” after another to nine new counts of rape and kidnapping as his lawyer vowed to go to war against the labs that have allegedly linked his client’s DNA to the crimes.

Alejandro Done, 47, of Boston was arraigned yesterday in Suffolk Superior Court on charges in connection with four attacks that took place between 2006 and 2010.

Assistant District Attorney David Deakin asked that Done be held pending trial, writing in a motion that Done is “profoundly dangerous to women, and no conditions of release can mitigate the extraordinarily serious threat he poses.” Done is already being held at MCI Cedar Junction as he begins a 12- to 15-year prison term after admitting to raping a woman who was waiting for an Uber ride last December.

Done provided a DNA sample in that case which triggered a database match and led prosecutors to charge him in connection with the four attacks. Done’s attorney, Tim Bradl, said he will be scrutinizing the DNA ?evidence.

“I have no intention of allowing Mr. Done to be some sort of repository for every open DNA case that the crime lab has,” Bradl said. “We are going to turn those DNA labs upside down. We are going to look at everything, we are going to oppose everything, we are going to fight this thing until the end.”

In his motion to the court, Deakin detailed the violent attacks. In July 2006, Done attacked a woman on Morrissey Boulevard near the JFK MBTA station and “beat her, pinned her to the ground, and raped her,” Deakin wrote. In June 2007, the ADA wrote, Done sexually assaulted a woman on the Esplanade after threatening to kill her.

Exactly one year after the first assault, July 29, 2007, Deakin wrote that Done threatened a woman with a knife before forcing her to the ground and raping her, making off with her cellphone and camera after the attack. Finally, in June 2010, Deakin wrote that Done ordered a woman into his car just a half-mile from the location of the first assault. Done threatened the woman with a large knife and raped her, the ADA wrote.

Bradl said the fact that Done has admitted responsibility for the 2014 attack and voluntarily provided a DNA sample “speaks volumes to his state of mind about these cases.

“There have been all sorts of missteps, misdeeds, incompetence, negligence, in all sorts of crime lab settings all across the country,” Bradl said. “We have no intentions of throwing in the towel and accepting whatever DNA evidence they have.”
