Cops Widen Search In Pa. Murders

Despite an Amber Alert for a missing 14-year-old girl, police say they have no new leads in the search for the girl's 18-year-old boyfriend who may have shot and killed her parents Sunday morning.

Authorities expanded their search for the missing pair across the eastern U.S. on Monday.

The girl's sister watched her father get shot to death as he was escorting an 18-year-old man from their home on Sunday after an argument, according to court records.

David G. Ludwig gunned down the missing girl's father and mother and took the girl away from the house at gunpoint, police said. Neither Ludwig nor Kara Beth Borden, who is believed to be Ludwig's girlfriend, has been seen since the slayings, and police are treating her disappearance as a potential kidnapping.

Lititz Police Chief William Seace told a news conference Monday morning that an Amber Alert for the two of them has been expanded to the entire eastern United States.

"We're feeling that because the parents were killed this could be an abduction, but we could be wrong," Seace told reporters Monday.

"It's all over the electronic signs over our interstates here in central Pennsylvania and throughout Pennsylvania, so the chief was very disappointed that nothing came in overnight: No leads, no phone calls," reports Shannon Davidson of CBS affiliate WHP-TV.

Michael F. and Cathryn Lee Borden, both 50, were found shot to death at the family's home in Warwick Township, about 60 miles west of Philadelphia, shortly after 8 a.m. Sunday.

"Carol was brought home by 18-year-old David Ludwig late Saturday night. That was cause for concern to her parents, so they asked he return in the morning," reports Davidson.

The couple's 9-year-old son ran to the home of neighbors, who called 911, police said.

Katelyn Borden, 13, told investigators her father and mother were shot after they argued with Ludwig for about an hour in their home near Lititz on Sunday morning.

"As they got near the front door, Katelyn Borden saw David Ludwig with a handgun pointed toward her father and Katelyn saw David Ludwig pull the trigger, heard a gunshot, and then she ran into the bathroom," according to a police affidavit.

She heard a second shot — presumably the one that killed her mother — while hiding in the bathroom. He then ran through the house calling for Kara, she told investigators.

The two had been seeing each other secretly, said a family friend.

"The parents really didn't like them hanging out," Stephanie Mannon, 16, said. "There was a big difference so that's kind of understandable. She's 14 and he was 18."

"(Cathryn) was concerned that Kara was boy crazy like many young teens, but she was e-mailing back and forth and she poured her heart out to me, 'What should I do,' and 'What a situation,' you know, trying to avoid tragedy," family friend Reba Zimmerman said on CBS News' The Early Show.

Police on Sunday night issued an arrest warrant for Ludwig on two counts of criminal homicide, one count of recklessly endangering and one count of kidnapping.

Ludwig, a white male with brown hair and brown eyes, was last seen driving his parents' red Volkswagen Jetta with Pennsylvania license plates EHH-0994. Borden is described as white, 5-feet-1 and 100 pounds, with brown hair with blond highlights. She was last seen wearing a black sweat shirt with "Pillar" across the front, blue jeans and black sneakers.

The Borden family had lived in the home for several years, said neighbor Tod Sherman, 47. Mike Borden worked for a printing company, and the children were home-schooled, he said.

Neighbors say Kara Beth and Ludwig were both home schooled and knew each other through a home school network, reports CBS News correspondent Sharyn Alfonsi.

"I know he's a Christian and he seemed like a really decent, nice sweet person," said Mannon. "I worked with him. I can't believe it happened."

Both Ludwig and Kara Borden maintain Web sites on the Internet. Hers refers to interests in soccer, art and her Christian faith. His blog says he enjoys "having soft air gun wars" and claims expertise in "getting in trouble."

Sherman described her father as "very smart and focused, a nice guy."

"They were super people," he said.

"I think in this community everyone is very shocked, simply knowing the Bordens as a kind, loving family," Zimmerman told Early Show co-anchor Julie Chen. "In this community, nothing like this ever happens."

The murders were the second violent incident in a week in normally quiet Lititz, a Lancaster County village known for its quaint shops, local artists and such attractions as the Sturgis Pretzel House, which bills itself as America's first pretzel bakery.

On Tuesday, police shot and killed a man hours after authorities said the suspect shot one of three officers who had gone to his home with a traffic warrant.
