Christmas lights turned on and a few last gunshots rang out in the woods last night as darkness crept over Upper Frederick Township in a rural, hilly stretch of Montgomery County.

Gunshots, in the height of deer-hunting season, aren't unusual here, even if they seem a tad too late and a little bit too close to home.

Neighbors on Snyder Road said they never thought anything was wrong Saturday night, until the police arrived.

Police say a teen was shot and killed and his adoptive father wounded during an argument outside a home on a steep, winding street.

Investigators are trying to determine whether the shootings were justified.

"I heard a shot, but I didn't think anything of it," said a neighbor, who asked not be identified.

State Police say Zachary Levin, 19, and Joshua Levin, 34, of Barto, Berks County, were shot outside 1705 Snyder Road, just up a gravel driveway from that neighbor's home.

A woman in the home was arguing with the alleged shooter and called the Levins to pick her up, police said.

The men began arguing outside the home and First Assistant Montgomery County District Attorney Kevin Steele said the Levins appeared to have brought baseball bats to the house.

Zachary Levin, a student at Boyertown Area Senior High School, was found dead in the driveway, police said.

Joshua Levin is being treated for gunshot wounds.

The alleged shooter has not been identified, but police say he called 9-1-1, remained on the scene and surrendered peacefully when officers arrived. That man was questioned yesterday, Steele said, but was released pending the outcome of the investigation.

No one answered the door at the home yesterday, although a pickup truck was parked out back. Neighbors said the man had lived in the home, about 40 miles from Philadelphia, only for a few months and hadn't caused any problems.
