West Chester Native, CHOP Nurse ID'd As Victim Of Main Line Killing

WEST CHESTER, PA — The woman who was shot and killed in Tredyffrin over the weekend has been identified as a West Chester native, a nurse at the Children's Hospital of Philadelphia, and a mother of three.

Megan Karyl Nieberle, 53, of Berwyn, was killed by Steve Jahn, 44, a man who had refused mental health treatment just hours before the killing, authorities said.

Nieberle was mourned in her obituary as a person of profound "warmth, humor, and loyalty."

She had worked for 27 years at CHOP, "where she touched the lives of countless patients, families, and colleagues," the obituary notes. She'd recently been appointed Nurse Manager of Surgical Services at CHOP's King of Prussia location.

Nieberle was born and raised in West Chester, and ultimately went on to graduate from Henderson High School and Millersville University. She was married to her husband, Gary, for 25 years. They shared three children whom they loved deeply: Ryann, Jamie, and Finnegan.

Beyond her work and her passion for her children and their sports, she loved the outdoors, time at the beach in Sea Isle City, hiking in Valley Forge Park, and exploring with her dogs Cooper and Jackson, the obit adds.

Investigators are still piecing together the stunning and horrific series of events on March 7 that led to the loss of widely loved and respected member of the community.

Jahn, who legally owned his firearms and had obtained a concealed carry permit, called 911 himself hours before the incident. Police said they attempted to escort him to Paoli Hospital to voluntarily commit himself, but he refused treatment when he arrived.

Jahn then drove back and forth throughout Tredyffrin, Easttown and Radnor over the next two hours, the affidavit says. The shooting occurred as Nieberle was driving on Contention Lane near Old State Road.

Memorial and funeral services for Nieberle are set for Sunday, March 29 at The Desmond Hotel in Malvern, beginning at 1 p.m.
