Linda Degnan told a judge Wednesday that Danielle and Jennifer Pamula talked to her at the store last December, concerned that they might have to leave their father's home.
“We’re going to kill him,” Degnan quoted Danielle as saying. “We will be here in March and he will not.”
Then Jennifer reportedly added: “He’s going to get his.”
The twins are accused of carrying out their plot well before March.
Danielle, 38, claimed she discovered her dad was dead after awaking from a nap.
Jennifer claimed she took an overdose of medicine before her father reportedly became hostile.
“I had to do it,” Jennifer told police while covered in blood and vomit. She reportedly left a recorded confession on her phone.
