Lititz, Pa. ? Police seized 54 guns from the home of an 18-year-old man charged with killing his girlfriend’s parents and fleeing the state with her, according to court documents filed Thursday.

Warwick Township police removed the collection of rifles, shotguns, handguns and ammunition Sunday from the home where suspect David Ludwig lived with his parents. The search occurred as police were still trying to find him and 14-year-old Kara Beth Borden.

Ludwig was being held without bail on murder and kidnapping charges after being flown back to Pennsylvania on Tuesday from Indiana, where police captured him.

Police allege Ludwig shot Michael and Cathryn Borden on Sunday at their home in Lititz following an argument over his relationship with Kara. The two had been secretly dating according to friends and witnesses.

Ludwig was arrested Monday after crashing his parents’ car into a tree in Belleville, Ind., during a police chase. Neither Ludwig nor the girl, who has not been charged, was injured.

Investigators have said they are treating Kara Borden as a victim but that the investigation is continuing.

It was unclear whether the confiscated weapons belonged to Ludwig or his parents.

David Ludwig apparently was an avid hunter and posted 20 pictures labeled “Hunting 2004” on a Web site.

Neither of Ludwig’s parents is licensed as a firearms dealer or collector, according to the national licensing center of the federal Bureau of Alcohol, Tobacco, Firearms and Explosives.

The Bordens were each shot once in the head with what authorities said was probably a .40-caliber handgun.
