The suspect, whose name was not immediately released, apparently had a grudge of some sort against the Mennonite religion and allegedly took his anger out on the three women, police in Lancaster County said.
The suspect allegedly broke into the Clay Township home Friday, tied up and assaulted the three women, ages 84-90, who were still hospitalized Sunday.
"They suffered multiple electrical shocks, were incapacitated and left," said North Lancaster County Regional Police Chief David Steffan. "They were unable to move for a long period of time. That could have led to bad things like blood clots and positional asphyxia."
The Intelligencer Journal in Lancaster/New Era, said the victims had apparently by shocked by "an incapacitation device," possible a cattle prod, and repeatedly beaten.
The man told the women he had a "rage" against Mennonites and read Bible verses while ransacking the home, police said.
