Early yesterday morning, authorities arrested Robert Tulloch, 17, and James Parker, 16, for the murders of Dartmouth College professors Half and Susanne Zantop.

The two teens were arrested in New Castle, Ind., while attempting to escape to California.

"They have been apprehended and are in our custody," said Kim Cronk, sheriff of Indiana's Henry County.

The popular professors were found stabbed to death in their home on Jan. 27. But investigators were largely silent about possible suspects until this past weekend.

On Saturday, the New Hampshire Attorney General's Office announced they had issued arrest warrants for the two teens, natives of Chelsea, Vt., for "acting in concert to cause the deaths of Half and Susanne Zantop by stabbing them multiple times in the head and chest."

A nation-wide manhunt for the young men ensued.

The men fled New Hampshire last Thursday in a silver Audi which belonged to a family member.

On Friday, the two abandoned the car at a Sturbridge, Mass. truck stop and hitchhiked with several truck drivers to Indiana, where they were subsequently apprehended, said Malinda Lawrence, a representative from the New Hampshire Attorney General's Office, in a press conference yesterday.
