Lancaster Co. man arrested following double stabbing at Dover-area party



David Ryan Kauffman surrendered to members of the U.S. Marshals Service in Lancaster County on Tuesday morning, according to Northern York County Regional Police.

Kauffman was arraigned and is being committed to York County Prison on $250,000 bail, police said.


Police are searching for a Lancaster County man who they say stabbed two people at a Dover Township party he hosted without permission early Monday morning in a vacant home.

David Ryan Kauffman, 18, of 11 Forever Lane in Paradise, is wanted on two counts each of aggravated assault and reckless endangerment, plus single counts of burglary, criminal trespass, simple assault and criminal mischief.

He goes by Ryan, according to court documents.

Northern York County Regional Police said they obtained a warrant for Kauffman's arrest Monday morning; his whereabouts are unknown. The U.S. Marshals Service's fugitive task force is assisting in the search, police said.

Police said Kauffman stabbed two 19-year-old men during an altercation during a party at a home in the 2900 block of Hemlock Drive just before 3 a.m. Monday.

The home is unoccupied, and Kauffman broke in to throw the party, according to Northern Regional Lt. David Lash. There is a connection between Kauffman and a relative of the homeowner, Lash said.

During the party, two men — Wesley Lynn and Connor MacDonald, both of the York area — started cooking hamburgers in the home's kitchen and were making a mess, which upset Kauffman because it wasn't his house, according to charging documents.

Lynn and MacDonald said they would clean up after cooking, police said. A short time later, an angry Kauffman confronted them again about leaving, police said.

At that point Kauffman made a comment that he had a gun and started walking to a back room of the home, charging documents state.

Lynn and MacDonald followed, saw Kauffman rummaging through a dresser drawer and, worried he was getting a gun, grabbed him by the shoulders, documents state.

That's when they were attacked by a knife-wielding Kauffman, according to Lash.

MacDonald suffered slashing and stabbing wounds to his torso, including to his upper chest, Lash said. He was in satisfactory condition Monday, a York Hospital spokeswoman said.

Lynn suffered a single knife wound to his torso, police said. He was treated at York Hospital and released, according to the spokeswoman.

After the attack, the victims fled the home and went to a parking lot in the 2800 block of Carlisle Road, where they called 911, he said.

Lash said officers went to the Hemlock Drive home, but that Kauffman and his party guests were gone.

Officers were able to track down other party-goers, who provided them with Kauffman's name, Lash said.
