A Monroe County man has been charged with killing his boyfriend at his home in Lancaster County early Wednesday morning.

Matthew VanZandt, 30, of the 100 block of Laurel Lake Road, Bartonsville, showed up at St. Luke’s Allentown campus Wednesday. He was covered in blood and told officials he had killed his boyfriend.

According to the affidavit of probable cause filed by Detective Nicholas Fritz of the Manheim Township Police Department:

At 12:48 a.m. officers Lucas Starsinic, John Brubaker and Jared McArther of the Manheim Township Police Department responded to the 400 block of Dickens Drive, Lancaster Township, for a possible domestic disturbance.

When officers arrived, they did not hear any noises or signs of a disturbance.

They knocked on the door, but nobody answered. They noticed a light coming from the top right window of the house.

Meanwhile, according to the dispatch, VanZandt entered St. Luke’s Hospital in Allentown covered in blood.

VanZandt told hospital personnel that he had just killed his boyfriend, whom he identified as Ian Shannon, 31, at the house in Manheim Township.

At 3:25 a.m., officers knocked on the door several times, but no one answered.

Police called the number, the phone rang several times and then the call dropped.

Starsinic called the number back several times, but the call did not connect.

A next-door neighbor came outside and asked if there was a problem. Starsinic said that he could not reach anyone inside the home.

The neighbor said he knew the code to open the garage door.

Police used the code to enter the home to check on Shannon based off what VanZandt had told Allentown Police Department officers.

Police entered a bedroom and found Shannon naked and lying on a bed. He was covered in blood and had suffered several visible stab wounds to his torso.

Officers also noticed blood had covered the majority of the bedroom, and checked for a pulse, but found none.

Township police spoke with the neighbor, who said he awoke to loud screaming coming from the home, and that he heard loud music for about 10 to 15 minutes.

The neighbor said he knew both men, that they were in a relationship and that they had domestic arguments in the past.

The neighbor also said that he believed the person screaming was Shannon.

Detective Chris Dissinger spoke with a registered nurse with St. Luke’s Allentown Campus, who told him that he interacted with VanZandt when he initially came into the emergency room.

VanZandt signed into the hospital for a hand injury, and the nurse noticed that VanZandt was saturated in blood.

He said the blood was not his and that the person who was the source of the blood was dead.

A nurse told police that she heard VanZandt tell the attending physician that he had stabbed his boyfriend.

When the security guard asked VanZandt if he had any weapons, he replied, “In my backpack is the knife that I used to stab my boyfriend with.”

VanZandt told police that he stabbed his boyfriend after an argument.

VanZandt said that he told Shannon he was going to end their relationship and “leave him,” when Shannon began mocking him and said that “he was not going to leave him.”

He said Shannon continued to mock him, so VanZandt pulled out his pocket knife and began to stab him several times.

VanZandt motioned to police that he stabbed Shannon in his face, neck and torso area. Police said that VanZandt remained calm and monotone as he told his account of what occurred.

VanZandt faces a charge of criminal homicide.

He is currently incarcerated in the Monroe County Correctional Facility and is awaiting arraignment.
