Cumberland County Prosecutor Arthur Marchand said police knew exactly who they were looking for based on physical evidence recovered from the victim's home on Overbrook Drive. Marchand declined to identify the evidence.
Police are continuing their investigation into the two other break-ins, involving a lone assailant who raped a 31-year-old woman and attempted to rape a 15-year-old girl.
Officials said they believed all three attacks - which occurred within a 2 1/2-hour period at homes within walking distance of one another - were related. Neither suspect has been charged with the two other crimes.
New Jersey State Police arrested Blackwell early yesterday in Buena Vista township, where he was pulled over in a routine traffic stop. He was turned over to Vineland police after state police learned of a warrant for his arrest.
Blackwell is scheduled to be arraigned at 1:30 p.m. today in Cumberland County Superior Court. Both Blackwell and Bell were being held at the county jail on $100,000 cash bail.
