Del. woman kills husband's alleged mistress before shooting self

A Delaware woman traveled to Pennsylvania to fatally shoot another woman, who was believed to be having an affair with her husband, before killing herself, police said Tuesday.

Jennair Gerardot broke into Meredith Chapman’s home in Radnor Township, Pa., waited for her and fatally shot her as soon as she walked in Monday night, police said at a press conference.

Gerardot then shot and killed herself. Their bodies were found in the back of the home, police said.

Cops said Gerardot knew her husband was having an affair with Chapman, 33, and that the slaying was a “calculated, planned attack.”

Detectives are investigating emails and text messages showing Gerardot planned the killing, police said. Authorities also found a bag possibly belonging to Chapman that contained a wig and clothing.

Gerardot’s husband was in the area and believed he was meeting Chapman for dinner, but he became concerned when she didn’t show up, police said.

Chapman was assistant vice president at Villanova University and also worked at the University of Delaware where she graduated from, according to her LinkedIn page. She also unsuccessfully ran for Senate in 2016.
