The calls for help came from a family member making a welfare check.
The 911 dispatcher that night said, "Caller just got to the mother in-law's house, found her with a reusable shopping bag on her head."
"I was horrified when the police came," neighbor Ginny Franke said.
Usually a quiet rural road, Franke had no idea this violence was unfolding next door.
"I was really scared. It really upsets me that something this close to home happened," Franke said.
Her husband Rich Franke thinks whoever committed this crime knew about the victim.
"Somebody knew this lady was living alone," Rick Franke said.
This is the latest violent home invasion in Chester County in what has been a string of seven since June.
Chester Co. Home invasions since Oct 2016: Chester Springs (Oct, Nov); Uwchlan TWP (Jan); Parkesburg (Feb); East Brandywine (Sunday) @6abc— Christie Ileto (@Christie_Ileto) February 28, 2017
Five of the incidents occurred in the last five months.
While some of those incidents may be connected, police say it does not yet appear this incident is connected.
However, an investigation into all of them continues.
