“I walked down the yard to address him and he never looked at me he just walked calmly toward his car calmly and drove away,” said Mary Johnston, who lives on the block.

Johnston says she was brought to her front lawn after hearing gunshots.

“I heard some shots and screaming,” she said. “I thought it was just some kids playing around and realized it sounded more serious.”

When she came outside she found herself face-to-face with the man she now believes shot her neighbor.

“I went down the yard to investigate and saw the suspect leaving the house,” Johnston said.

Police say that around 12:30 p.m. 30-year-old Greg Feldman, of Harleysville, approached that home and knocked. Feldman then shot the 48-year-old woman twice in her chest when she opened the door, according to police.

According to Steele, Feldman was known to the woman and her family.

“So this is not an unknown assailant and we know that there was a relationship, familiar relationship in the past and we need to find him as soon as we can,” said Steele.

Since learning more about what happened, Johnston reflects on the man she saw walking away from the scene.

“Just calm and determined. It looked like he was carrying something. It looked like his arm was bent and he was carrying something bulky underneath his sweat jacket,” she said. “He didn’t seem to be in any rush or anything. That would have been a red flag for me.”

Police say the suspect was last seen driving a 2016 black Mazda sedan with Pennsylvania tags KFC4605.

He’s considered armed and dangerous. Anyone with any information is asked to call police by dialing 911.

The woman was transported to Grand View Hospital in Sellersville. There was no word on her condition.

Authorities say until Feldman is in police custody they will continue to have a heightened security presence at the hospital. That means all hospital visitors will need to enter through the main lobby entrance only, and check in with staff. All other hospital services are following a normal business schedule.
