A variation on that theme:
A proton walks into a bar and sees a beautiful neutron sitting there.
He goes up to her and says: "I think we've met before."
She says: "I don't remember. Are you sure?"
He says: "I'm positive."

That's actually what the article says. The neighbor testified that she THOUGHT the person knocking was a neighbor boy, but it was actually Michelle Kehoe.

Hinde testified a woman or as she first thought, a neighbor boy, knocked on her door early Oct. 27, and the boy was laying against the door as she opened it. The boy was covered in blood and she called 911. As she was calling, the boy crawled into her house and laid down in the fetal position on her kitchen floor.

Hinde said she realized at this point it wasnt the neighbor boy. The person had a difficult time communicating with her. She couldnt breathe very well and was writing information on paper. She wrote down a phone number and told Hinde her name, Michelle Kehoe, so Hinde called the number and told them Kehoe was hurt.
