The Concord police have arrested one of two people stabbed last week in a downtown parking garage and said they believe she and others had planned to rob the second victim, a 42-year-old man, after he paid to have sex with her.



Pierce Osgood, 18, of Warren Street was detained Wednesday and has been charged with robbery and misdemeanor breach of bail. She is being held on $10,000 cash bail.



Osgood and six others, including the man, a registered sex offender named John Dora, were stopped by the police about 9 p.m. Sept. 28. According to an arrest affidavit, officers heard screaming and squealing tires coming from the Durgin Block Parking Garage, located less than a block from their headquarters on Green Street.



Both Osgood and Dora were taken to Concord Hospital and treated for non-life-threatening wounds – Pierce to her upper back, Dora a punctured lung. The four other witnesses, all associates of Osgood’s, were interviewed at the scene, the police said.



No one besides Osgood has been arrested in the incident, though additional information – and new charges – are expected, the police said.



Despite differing witness accounts, the police said they suspect that Osgood and another woman, Stephanie Sousa, 22, offered to perform sexual acts on Dora in his car, and that the plan had been to beat him up afterwards and steal what cash he had. Osgood told investigators that the group needed money and had intended to rob Dora, according to the affidavit.



But the plot began to unravel when Dora asked Sousa to leave, Osgood said. Sousa and the others, all men, approached the car and one of the men, 20-year-old Trevor Partridge, punched Dora through the driver’s-side window. Dora then locked the doors, put the car in reverse and fled the scene with Osgood still inside, she said.



Osgood told investigators that she believed Dora had about $2,000 on him at the time.



Partridge and the two other men, Scott “JR” Perkins and Douglas Wyman, both 20, gave alternative narratives. Perkins, Osgood’s boyfriend, said Dora had approached her first and appeared to have assaulted her while in the car, or at the least held her against her will. Wyman said he thought Dora had “stabbed himself,” according to the affidavit.



Dora later claimed that Osgood unexpectedly jumped into his passenger seat, held a knife to his throat and demanded money.



Sousa refused to speak with officers the night of the attacks, but according to the affidavit, an officer overheard her tell an unidentified bystander something to the effect of, “This is all their fault! They wanted to set him up and rob him! This is because Pierce has been prostituting herself.”



The police said Osgood is a reported drug addict and has been arrested eight times in the past 10 months for related offenses, including simple assault. She had been out on bail at the time of the incident.



Osgood is scheduled for a probable cause hearing Friday in Concord’s district court.
