A man has been charged with abusing his mother's corpse and leaving it in a car outside a home in the north-eastern US.
According to charging documents, Kevin Ahn's estranged sister is the one who called police on Monday after she saw Ahn, 31, "acting weird" outside apartment blocks near Manheim in the state of Pennsylvania.
She reported he was "talking in numbers" and speaking gibberish. She told police she saw him enter their mother's Toyota RAV4, write on a piece of paper and exit the vehicle.

The woman approached and read the handwritten note, which had been placed on the dashboard. Police said the note read, in part, "Mom is in car. I'm sorry. Please give her a funeral. My brain is fried. My mom lied, she gave me fake money from the N.A. so did my employees. I lost my mind. Forgive me. Please call my sister."
When the sister asked Ahn about the note, he got back into the car and drove away.
Ahn returned about 30 minutes later, and his sister and her husband went outside to confront him.
Police said the sister told them she then saw what appeared to be a human leg hidden underneath clothing and household items in the backseat of the SUV.
She tried to question Ahn, but he ran away. Police found him running in nearby streets a short time later, according to the Lancaster County District Attorney's Office.
Police and EMS searched the car and found the deceased woman, who has been identified as Hyun Ahn, 61.
According to police, the woman had a purple face, marks on her neck and hemorrhaging in her eyes.
The DA's office said in a statement Ahn is accused of abusing the corpse of his mother.
