A couple has been charged in the fatal shooting of their 2-year-old boy Sunday in East Penn Township. Christian Zawoiski died at St. Luke’s Lehighton Campus as a result of a single gunshot to the head.

According to the affidavit of probable cause filed by Trooper Nicolas De La Iglesia of the Pennsylvania State Police Lehighton barracks:

PSP Lehighton troopers responded to the 100 block of Laurel Spring Road, and talked to the boy’s parents, Andrew Zawoiski, 28, and Christina McFarland, 24, both of Lehighton.

Zawoiski and McFarland said they have a handgun at the residence and normally have it readily available for protection when they fall asleep.

Police saw McFarland placing a vape pen near a vehicle which was parked in the driveway, and asked her about it. McFarland said that it was her vape pen.

Trooper Michael Sofranko then placed the vape pen on the porch, and Zawoiski and McFarland were transported to the barracks for interviews.

Zawoiski said that he put the victim to bed at around 11 p.m. Saturday in the master bedroom.

He said both he and McFarland were watching television on the couch and placed his handgun in a basket next to the couch in the living room.

Zawoiski said that the handgun was fully loaded with one round in the chamber, and that both he and McFarland slept on the couch in the living room.

The boy awoke at around 9:30 a.m. Sunday, as did McFarland. Zawoiski awoke at around 10 a.m. and remained at the residence throughout the day.

At around 3 p.m. Zawoiski was showering and heard a bang, ran out and asked McFarland what had happened. McFarland was holding the boy and they went outside and contacted 911 while performing CPR on the porch.

Zawoiski said that he normally places the gun high up - in a dresser or cabinet for safe keeping from the victim. He said that he smoked marijuana about four or five days ago and that he and McFarland use Suboxone regularly; he has a prescription for the medication, but McFarland does not and that she takes his medication.

Zawoiski said that both he and McFarland took Suboxone in the morning, and that his Glock 19X 9 mm pistol was used during this incident.

McFarland was between the kitchen and living room with the victim and went onto the computer when she heard the gunshot.

McFarland said that she was aware the loaded handgun was in the basket in the living room and did not move it because she was keeping an eye on the victim and felt that Zawoiski would move the gun when he finished getting a shower.

Cpl. Shawn Noonan conducted drug influence evaluations on Zawoiski and McFarland and said that both showed signs of impairment.

A search warrant was executed, and a fully loaded 9 mm Glock was recovered from the couch. A holster with no clasp or safety was discovered in the small basket next to the couch. The basket also contained a children’s book and toys.

An AR-15 semi-automatic rifle loaded with 30 rounds was discovered leaning against a piece of furniture in the master bedroom.

A loaded Taurus .22-caliber pistol was discovered in an unsecured drawer in the master bedroom.

A small amount of suspected marijuana was discovered in a glass candle jar lid on a shelf near the couch and storage basket.

Suboxone and several unknown pills were also discovered within the residence, and drug paraphernalia, which included a marijuana grinder and a wooden box with a metal cigarette style smoking device discovered in a backpack with the master bedroom.

Both Zawoiski and McFarland face charges of involuntary manslaughter; endangering welfare of children - parent/guardian/other commits offense; marijuana - small amount personal use; use/possession of drug paraphernalia; and recklessly endangering another person.

They were taken to Carbon County Correctional Facility in lieu of 10 percent of $50,000 bail. A preliminary hearing is June 10.
