Police Chief Richard Garipoli also told The Early Show co-anchor Julie Chen that murder suspect David Ludwig is "being very quiet" and seems to be in a state of shock.
Ludwig was taken into custody Monday after he crashed his parents' car head-on into a tree in Belleville, Ind., 20 miles west of Indianapolis, and some 600 miles from where the killings took place.
Ludwig was captured with Kara Beth Borden in the passenger seat after a high-speed chase.
Garipoli said that Borden is considered a victim at this point as there's not enough information yet to know whether she faces any charges. It was still unclear whether Ludwig kidnapped her or if she left with him willingly after her parents, Michael F. and Cathryn Lee Borden, were shot to death early Sunday.
Garipoli also says Kara Beth is "doing OK," but having "spurts of crying." She's due to return from Indiana to Pennsylvania. The girl's two younger siblings and the rest of her family are "holding together."
Neighbors say Kara Beth and Ludwig were both home schooled, and knew each other through a home school network, CBS News correspondent Sharyn Alfonsi reports.
"It's totally changed the fabric of our community," says one neighbor of the Borden's murder. "They were wonderful people and they will be very sadly missed."
Police say Ludwig killed Michael and Cathryn Borden after they and their daughter argued about her curfew when she came home late. The shootings happened at the family's home near Lititz, Pa., about 60 miles west of Philadelphia.
Ludwig could waive extradition, clearing the way for authorities to take him back to Pennsylvania to face charges. Otherwise, an extradition hearing would be held Tuesday or Wednesday, said Hendricks County Prosecutor Patricia Baldwin.
He faces preliminary charges in Indiana of criminal recklessness and resisting law enforcement, authorities said. Police in Pennsylvania issued an arrest warrant for Ludwig on charges of criminal homicide and kidnapping.
Few details were known about the pair's trip. Authorities said they don't know the route they traveled, if they had family or friends in Indiana or if they were simply passing through the state.
The Bordens, both 50, were apparently shot once each in the head, authorities said. Mike Borden worked for a printing company, and his children were home-schooled, said neighbor Tod Sherman. Sherman said the family knew Ludwig through a home-schooling network.
Kara's 13-year-old sister, Katelyn, told investigators her parents were shot after they argued with Ludwig for about an hour, according to court papers.
