(CNN) -- Authorities appear to be a step closer in an expedited process to determine whether Ariel Castro fathered the daughter of Amanda Berry, one of the three women police say was held captive in his Cleveland home for years.
Preliminary results of Castro's DNA profile have been sent to Cleveland police, the Ohio attorney general's office said Friday.
Police have said they plan to use the information to determine the paternity of Berry's 6-year-old daughter, who authorities believe was born in captivity.
Berry, her daughter and two other women were rescued Monday after the women were held at Castro's home for the better part of a decade, police said.
Castro was arraigned Thursday in a Cleveland court on four counts of kidnapping and three of rape. He is being held with bail set at $8 million -- $2 million for each of the three women and the child.
Investigators had asked the state crime lab to expedite the DNA profile -- something that typically takes 20 days, Ohio attorney general's office spokesman Dan Tierney said this week.
