Sitanan Satsaksit was on the phone to her brother early in the evening on 4 June when he told her to hold the line. Wanchalearm, also known as Tar, was handing over a few dollars for meatballs at a stall opposite his home in the Cambodian capital, Phnom Penh.
Then Sitanan heard noise coming from the other end of the line.
“I heard a loud bang. At first I thought he had a car accident as he shouted ‘I can’t breathe, I can’t breathe,'” she tells the BBC.
