This suspect showed he was willing to take advantage of women," said Conley, adding that there was a "strong possibility he has done this before. During a search of Markoff's house, police found a semi-automatic weapon, plastic ties and duct tape, Conley said.
He added that there is a "strong possibility" that Markoff has attacked other women and asked other potential victims to come forward. Authorities said they followed cell phone and computer records to Markoff, linking an e-mail used to set up appointments on Craigslist with the two women who were attacked to his address in Quincy, Mass.

Police said they tracked Markoff down using surveillance videos at three hotels. In photos taken from hotel cameras, the man police have been seeking in connection with the crimes appears to be fixated on a BlackBerry.
Investigators said that Blackberry is what led them to Markoff. A police source close to the investigation said cops found Markoff by tracing Craigslist e-mails.
Markoff's friends and neighbors are shocked. After all, Markoff, a second-year medical student at Boston University, had no criminal history and was engaged to be married to a woman he met more than three years ago when they were volunteers in an emergency room.

But for all the nice things they had to say about Markoff, his friends said there was a bit of mystery about him, though nothing overtly nefarious. Friends said they didn't even know he and McAllister were engaged. Though they agreed they seemed like a nice normal couple, his friends said they thought the two were simply dating.
The couple's Web site, once flooded with well wishes from friends and family, is now filled with cruel postings from strangers, many directed at McAllister. The site had detailed how they met when McAllister was a senior at the University of Albany and Markoff a sophomore.
Their wedding date was set for Aug. Markoff's arrest came just hours after Warwick, R. Police in both Boston and Rhode Island have said they believe the attacks may have been carried out by the same person. On Monday, investigators released a clear photograph of the suspect taken during the most recent attack in Warwick.
A series of images show the suspect inside the Holiday Inn Express Hotel last Thursday evening, the scene of an attempted robbery of a woman. The man seen in the pictures taken in the hotel closely resembles the man seen in a surveillance camera photo that was released after Brisman was found dead just days earlier. Detectives have also a match among plastic zip-tie cuffs used to bind all three women.
Two law enforcement sources told ABC News that the plastic restraints were being investigated after they were used to bind the hands of the victims. The man captured on a series of surveillance cameras in Boston's upscale Back Bay was a something, clean-cut blond man who was seen leaving a luxury hotel where police said Brismana masseuse, was shot and killed just moments before in her room.
Brisman's death is the second in a series of crimes against women who police say advertised on Craigslist. Finally, late Thursday night -- an hour south in Rhode Island -- there was a similar attempted robbery. Police said all the women were tied up and threatened at gunpoint.
It is believed that Brisman may have tried to resist her attacker as he tried to bind her wrists, and was shot.
A common thread among all of the victims is that they all had posted Craigslist advertisements for some sort of massage or exotic dance. Investigators say that's a vulnerable venue to offer personal services.
It's really an ideal environment for criminals. Gay Talese, an author who writes on the sex trade, whose most popular book, "Thy Neighbor's Wife," came out long before sites like Craigslist existed, said such sites are making the problem much bigger because the players are anonymous. Just last November, Craigslist entered into an agreement with 40 state attorneys general to eliminate some of the anonymity by requiring credit cards to post these erotic .
The company CEO told ABC News they are deeply saddened by the events and are "evaluating the incident to see if they can better protect Craigslist users. But experts say little can be done to prevent criminals from using the Internet to stalk their prey. After the arrest today, Craigslist CEO Jim Buckmaster issued a statement, saying, "We are very pleased to hear that the person alleged to have committed these crimes has been arrested, and we will continue to provide law enforcement agencies with any assistance necessary to prosecution of the case.
